FAQs & Myths for Coronavirus

Q001: What is a novel coronavirus?

A001: A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

Q002: What is coronavirus disease 2019 (COVID-19)?

A002: Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. There are many types of human coronaviruses, including some that commonly cause mild upper-respiratory tract illnesses. COVID-19 is a new disease, caused by a novel (or new) coronavirus that has not previously been seen in humans. Current symptoms reported for patients with COVID-19 have included mild to severe respiratory illness with fever, cough, and difficulty breathing.

Q003: Can people in the U.S. get COVID-19?

A003: Yes. There have been cases of COVID-19 in the U.S. related to international travel, person-to-person spread, and reported community spread in parts of the United States. This is a rapidly evolving situation and CDC updates the risk assessment as needed

Q004: Are there any vaccines or other medical products to prevent COVID-19?

A004: At this time there is no vaccine to prevent coronavirus disease 2019 (COVID-19). The FDA is working with vaccine developers and other researchers and manufacturers to help expedite the development and availability of medical products such as vaccines, antibodies, and drugs to prevent COVID-19.

Q005: Are antibiotics effective in preventing or treating COVID-19?

A005: No. Antibiotics do not work against viruses; they only work on bacterial infections. Antibiotics do not prevent or treat coronavirus disease (COVID-19), because COVID-19 is caused by a virus, not bacteria.

Q006: Are there any FDA-approved drug products or medicines to treat COVID-19?

A006: At this time, there are no FDA-approved drug products to treat COVID-19. The FDA is working with drug manufacturers and investigational new drug sponsors to expedite the development and availability of COVID-19 treatments. Read more about FDA’s actions to address the novel coronavirus with medical countermeasures.

Q007. Will Miracle Mineral Solution (MMS) cure COVID-19?

A007: No. Miracle Mineral Solution does not cure COVID-19 and has not been approved by the FDA for any use. The solution, when mixed, develops into a dangerous bleach which has caused serious and potentially life-threatening side effects. For more information, see: FDA warns consumers about the dangerous and potentially life threatening side effects of Miracle Mineral Solution and Danger: Don’t Drink Miracle Mineral Solution or Similar Products.

Q008: Is there a test for COVID-19?

A008: During public health emergencies declared under section 564 of the FD&C Act, the FDA is able to issue an Emergency Use Authorizations (EUAs) when certain criteria are met that allows for the use and distribution of potentially life-saving medical products to diagnose, treat, or prevent the disease, which can include diagnostic tests. Accordingly, the FDA has issued EUAs authorizing the use of diagnostic tests to detect the virus, called SARS-CoV-2, that causes COVID-19.

The FDA has also issued new policies and guidance to achieve more rapid testing capacity in the U.S.

Because the virus that causes COVID-19 is new, currently there is no FDA-approved or cleared test to diagnose or detect COVID-19.

Q009: When will other diagnostic tests for COVID-19 be authorized?

A009: More than 100 companies have requested and received the FDA-developed EUA template for diagnostics for this outbreak. This template will help to expedite the development and authorization of other diagnostic products under EUAs. The templates for these diagnostic testing EUA submissions are now available on our website. If you need additional information, please refer to the FAQs on Diagnostic Testing for SARS-CoV-2.

Q010: What is the difference between a facemask and an N95 respirator?

A010: See CDC’s infographic: Understanding the Difference: Surgical Masks and N95 Respirators. More information on personal protective equipment, including surgical masks (facemasks) and N95 respirators, is available on the FDA’s website.

Q011: Will there be food shortages?

A011: There are no nationwide shortages of food, although in some cases the inventory of certain foods at your grocery store might be temporarily low before stores can restock. Food production and manufacturing are widely dispersed throughout the U.S. and there are currently no wide-spread disruptions reported in the supply chain.

FDA is closely monitoring the food supply chain for any shortages in collaboration with industry and our federal and state partners. We are in regular contact with food manufacturers and grocery stores.

Q012: Are food products produced in the United States a risk for the spread of COVID-19?

A012: There is no evidence to suggest that food produced in the United States can transmit COVID-19.

Q013: Is the U.S. food supply safe?

A013: Currently there is no evidence of food or food packaging being associated with transmission of COVID-19.

Unlike foodborne gastrointestinal (GI) viruses like norovirus and hepatitis A that often make people ill through contaminated food, SARS-CoV-2, which causes COVID-19, is a virus that causes respiratory illness and not gastrointestinal illness, and foodborne exposure to this virus is not known to be a route of transmission.

It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads. That’s why it’s always critical to follow the 4 key steps of food safety—clean, separate, cook, and chill.

Q014: Should food workers who are ill stay home?

A014: CDC recommends that employees who have symptoms of acute respiratory illness stay home and not come to work until they are free of fever (100.4° F [37.8° C] or greater using an oral thermometer), signs of a fever, and any other symptoms for at least 24 hours, without the use of fever-reducing or other symptom-altering medicines (e.g. cough suppressants). Employees should notify their supervisor and stay home if they are sick. We recommend that businesses review CDC’s interim guidance for businesses and employers for planning and responding to coronavirus disease.

Q015. How can you get tested for the new coronavirus?

A015. You need a doctor’s order to get a COVID-19 swab test. But even if your doctor would like to have you tested, a limited number of tests and overcrowded healthcare facilities have made the criteria for getting tested quite strict. Displaying symptoms like a cough or fever is generally not enough in an otherwise healthy person to warrant a test. Those who are already hospitalized, who have chronic conditions, or have been recently exposed to an infected person or region will take priority.

Regardless of whether or not you think you’re eligible for a test, if you’re concerned about having COVID-19, you should contact your healthcare provider. They can tell you the appropriate next steps based on your history and the area where you live. More tests are being developed, and the goal is to test everybody who needs to be tested.

Q016. Is it true that only someone with COVID-19 symptoms can pass it on?

A016. The World Health Organization (WHO) director-general previously suggested people already displaying COVID-19 symptoms—such as coughing, fever, or shortness of breath—were the biggest drivers of viral transmission. In other words, if you’re not showing symptoms, it’s not likely you can pass the virus on. The Centers for Disease Control and Prevention (CDC) backs this idea, adding that some spread may be possible before people show symptoms, although that’s not the main way the virus spreads.

One example of potential COVID-19 spread prior to symptoms includes the Biogen company meeting in Boston, Massachusetts, which has been pinpointed as the source of most cases in the state. Over 100 employees from all over the world—and now, their close contacts—have tested positive for COVID-19 in the days and weeks after attending the meeting. Supposedly, nobody showed symptoms during the two-day conference in February where it initially spread. An investigation into the conference—as well as a closer look at symptom status—is ongoing.

Globally, researchers are highlighting other examples of COVID-19 transmission that may have occurred before people showed symptoms. While published ahead of peer-review and print, an analysis of data from Singapore suggests 48% of cases resulted from pre-symptomatic transmission. The same study puts that statistic at 62% for cases in Tianjin, China.

Q017. Is COVID-19 going to become seasonal? Can you get it twice in one season?

A017. The 2009 swine flu pandemic occurred because of an outbreak of a new type of influenza A virus: H1N1. But now, H1N1 is considered a normal type of seasonal flu. Since COVID-19 is the result of a new type of coronavirus—SARS-CoV-2—it’s logical to think the same thing might happen, and that it could become less severe in years to come. But experts think it’s too soon to say.

“As of now, it is too early for us to know if this will be a seasonal virus that changes slightly from year to year like influenza does,” Joseph Khabbaza, MD, a pulmonologist at Cleveland Clinic, tells Verywell. “If similar to other respiratory viruses, it is unlikely to get COVID-19 twice in one season.”

Q018. Should you cancel any routine doctor’s appointments unrelated to COVID-19?

A018. Healthcare providers have mixed opinions on keeping routine appointments right now, and it may depend on where you live. As for Dr. Khabbaza? He recommends rescheduling or trying telemedicine.

“We would recommend, for the time being, cancelling all non-essential in-person doctor's appointments,” he says. “Many health systems are now providing free virtual visits to take the place of the office visits, allowing you to see your doctor from home. If virtual options are not available with your doctor, check with them to see if they feel it is appropriate for you to push back your appointment. This advice holds especially true for those older than 60, but I would advise anyone to avoid healthcare facilities unless truly needed.”

Q019. What does “flattening the curve” mean?

A019. Either the phrase “flattening the curve” or an image of the curve itself might be familiar. The origin of this graph is pretty complex; a population health analyst named Drew A. Harris, DPM, MPH, pulled information from a CDC paper, The Economist, and his own experience as a pandemic preparedness instructor to create it. But the concept behind it is relatively simple.

Without the proper protections in place, our society will see a sudden spike in COVID-19 cases that is way too high for our healthcare systems to facilitate. As a result, not everyone will get adequate treatment, and more people will die. The alternative? Put protective measures in place—like social distancing—that prevent that spike from happening. COVID-19 will spread more slowly, allowing doctors, researchers, and other healthcare professionals enough time and resources to react. The duration of the virus in the community will be longer, but it will be more manageable.

Q020. What does it mean to "shelter in place?”

A020. Sheltering in place is a safety precaution that is sometimes used in conjunction with natural disasters or other emergencies. Generally, people are asked to remain in an indoor location until it is safe to go outside. If you and your loved ones are asked to "shelter in place" in connection with COVID-19, this means that you should stay home unless you need to go outside for an essential reason, such as to get food or seek medical aid. If you have an essential job, you may be asked to still commute to work.

You should not congregate in groups, and you should stay at least six feet away from others outside your home. Your local government's instructions will provide more detailed information. Some communities in the U.S., including San Francisco, have asked community members to shelter in place as a way to limit the amount of possible COVID-19 infections. Staying put indoors helps communities stay safe as a whole.

Q021. Can kids get COVID-19?

A020. While children can get the new coronavirus, both the WHO and the CDC report they’re much less likely to contract it than adults. If they do, symptoms will be the same, but will likely be milder, and could potentially include diarrhea and vomiting.

Adults should be less concerned about catching COVID-19 from a child than they should be about potentially spreading it to a child. According to the WHO, “preliminary data from household transmission studies in China suggest that children are infected from adults, rather than vice versa.”

Q022. Can pets infect humans with COVID-19?

A022. COVID-19 is part of a larger group of coronaviruses. Some viruses in this group can cause illness in animals, including livestock, camels, and bats. While it's rare, those infections can spread to humans, as was the case with older coronaviruses SARS and MERS. Is animal to human transmission also possible with COVID-19?

While it's possible (but unconfirmed) that COVID-19 originally spread from an animal to a human, the CDC has no evidence that livestock, wild animals, or pets are causing its spread in the U.S. at this time. It is being passed person-to-person, and there are no reported cases in pets or other animals.1

Cats and dogs can get their own strains of coronavirus: feline coronavirus and canine coronavirus. However, these are short-lived intestinal infections with no link to COVID-19 and no risk to humans.

While they can't put you at risk for COVID-19, cats and dogs can carry many germs. Wash your hand for at least 20 seconds after handling animals and their waste.

Q023. Is food delivery safe right now?

A023. While we can’t be the judge of whether or not your favorite local restaurant is taking all necessary sanitary precautions, we can ask a doctor for their opinion.

“Having food delivered is felt to be safe at this time, but an emphasis on disinfecting and avoiding close contact with people remains,” Dr. Khabbaza says. He offers three tips for food delivery:

  • Ask to have the food delivered to your doorstep rather than directly handed to you

  • Wipe down any food container with a disinfectant

  • Wash your hands immediately after accepting the delivery and handling the container

Q024. Can mosquitos transmit COVID-19?

A024. According to the WHO, there is no evidence that mosquitos can pass on COVID-19.1 It's a respiratory disease, not a blood-borne disease, and is currently known to spread through droplets discharged by coughing, sneezing, and runny noses.

Q025. Are swimming pools safe?

A025. The CDC says there is no evidence that COVID-19 can be spread through pools and hot tubs.1 Normal care and maintenance, like using chlorine or bromine, should inactivate or remove any viruses.

Q026. What is the Difference Between Quarantine and Isolation ?

A026. While you might see the words “quarantine” and “isolation” used interchangeably, they actually refer to two separate processes. Both isolation and quarantine can help limit the spread of disease, but the process used depends on whether someone is actively sick or not.

Isolation -
Someone who is already sick with a communicable disease is separated from healthy people.

Quarantine -
Someone who is not yet sick—but has been exposed to a contagious disease— is separated from healthy people

Q027: How long COVID-19 can live on common surfaces?


  • Air - 3 hours

  • Copper - 4 hours

  • Cardboard - 24 hours

  • Stainless Steel - 2-3 days

  • Polypropylene plastic - 3 days

Q028:  What to do in the initial symptom of corona ?

A028: Whenever symptoms like fever, cold, red eyes appear, the first thing to do is to isolate the person as well as in case of cough and fever, seek immediate corona test and consult a doctor.

Q029. What to do during home isolation ?

A029. Take the medicine on time , exercise the lungs , keep track of the temperature and oxygen level , the fever does not go down despite taking the medicine , if the score on CT scan increases, take precaution that the virus is active.

Q030. How is a lung infection detected ?

A030 Checking the oxygen level and pulse rate in the body , then walking for 6 minutes and immediately checking the oxygen and pulse rate and if it is reduced by 5 digits, there is a possibility of pneumonia in the lungs.

. What is CT SCAN ?


FACTs For Coronavirus

FACT-001: The new coronavirus CANNOT be transmitted through mosquito bites.

To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes. The new coronavirus is a respiratory virus which spreads primarily through droplets be transmitted through generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water. Also, avoid close contact with anyone who is coughing and sneezing.

FACT-002: Does the new coronavirus affect older people, or are younger people also susceptible?

People of all ages can be infected by the new coronavirus (nCoV-2019). Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus. WHO advise people of all age to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.

FACT-003: Are antibiotics effective in preventing and treating the new coronavirus?

No, antibiotics do not work against viruses, only bacteria. The new coronavirus (2019-nCOV) is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment. However, if you are hospitalized for the 2019-nCoV, you may receive antibiotics since bacterial co-infection is possible.

FACT-004: Taking a hot bath does not prevent the new coronavirus disease

Taking a hot bath will not prevent you from catching COVID-19. Your normal body temperature remains around 36.5°C to 37°C, regardless of the temperature of your bath or shower. Actually, taking a hot bath with extremely hot water can be harmful, as it can burn you.The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.

FACT-005: Cold weather and snow CANNOT kill the new coronavirus

There is no reason to believe that cold weather can kill the new coronavirus or other diseases. The normal human body temperature remains around 36.5°C and 37°C, regardless of the external temperature or weather. The most effective way to protect yourself against the new coronavirus is by frequently cleaning your hands with alcohol-based hand rub or washing them with soap and water.

FACT-006: COVID-19 can be transmitted in areas with hot and humid climates

The COVID-19 virus can be transmitted in any climate, including areas with hot and humid weather. The best way to protect yourself against COVID-19 is by maintaining physical distance of at least 1 metre from others and frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.

FACT-007: Being able to hold your breath for 10 seconds or more without coughing or feeling discomfort DOES NOT mean you are free from the coronavirus disease (COVID-19) or any other lung disease.

The most common symptoms of COVID-19 are dry cough, tiredness and fever. Some people may develop more severe forms of the disease, such as pneumonia. The best way to confirm if you have the virus producing COVID-19 disease is with a laboratory test. You cannot confirm it with this breathing exercise, which can even be dangerous.

FACT-008: Exposing yourself to the sun or to temperatures higher than 25C degrees DOES NOT prevent nor cure COVID-19

You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19. To protect yourself, make sure you clean your hands frequently and thoroughly and avoid touching your eyes, mouth and nose.

FACT-009: 5G mobile networks DO NOT spread COVID-19

Viruses cannot travel on radio waves/mobile networks. COVID-19 is spreading in many countries  that do not have 5G mobile networks. COVID-19 is spread through respiratory droplets when an infected person coughs, sneezes or speaks. People can also be infected by touching a contaminated surface and then their eyes, mouth or nose.

FACT-010: Drinking methanol, ethanol or bleach DOES NOT prevent or cure COVID-19 and can be extremely dangerous

Methanol, ethanol, and bleach are poisons. Drinking them can lead to disability and death. Methanol, ethanol and bleach are sometimes used in cleaning products to kill the virus on surfaces — however you should never drink them. They will not kill the virus in your body and they will harm your internal organs. To protect yourself against COVID-19, disinfect objects and surfaces, especially the ones you touch regularly. You can use diluted bleach or alcohol for that. Make sure you clean your hands frequently and thoroughly and avoid touching your eyes, mouth and nose.

FACT-011: Do vaccines against pneumonia protect you against the new coronavirus?

Methanol, ethanol, and bleach are poisons. Drinking them can lead to disability and death. Methanol, ethanol and bleach are sometimes used in cleaning products to kill the virus on surfaces — however you should never drink them. They will not kill the virus in your body and they will harm your internal organs. To protect yourself against COVID-19, disinfect objects and surfaces, especially the ones you touch regularly. You can use diluted bleach or alcohol for that. Make sure you clean your hands frequently and thoroughly and avoid touching your eyes, mouth and nose.

FACT-012: Spraying or introducing bleach or another disinfectant into your body WILL NOT protect you against COVID-19 and can be dangerous

Do not under any circumstance spray or introduce bleach or any other disinfectant into your body. These substances can be poisonous if ingested and cause irritation and damage to your skin and eyes. Bleach and disinfectant should be used carefully to disinfect surfaces only.  Remember to keep chlorine (bleach) and other disinfectants out of the reach of children.

FACT-013: COVID-19 IS NOT transmitted through houseflies

To date, there is no evidence or information to suggest that the COVID-19 virus is transmitted through houseflies. The virus that causes COVID-19 spreads primarily through droplets generated when an infected person coughs, sneezes or speaks. You can also become infected by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands. To protect yourself, keep at least 1-metre distance from others and disinfect frequently-touched surfaces. Clean your hands thoroughly and often and avoid touching your eyes, mouth and nose.

FACT-014: Adding pepper to your soup or other meals DOES NOT prevent or cure COVID-19

Hot peppers in your food, though very tasty, cannot prevent or cure COVID-19. The best way to protect yourself against the new coronavirus is to keep at least 1 metre away from others and to wash your hands frequently and thoroughly. It is also beneficial for your general health to maintain a balanced diet, stay well hydrated, exercise regularly and sleep well.

FACT-015: Thermal scanners CANNOT detect COVID-19

Thermal scanners are effective in detecting people who have a fever (i.e. have a higher than normal body temperature). They cannot detect people who are infected with COVID-19. There are many causes of fever. Call your healthcare provider if you need assistance or seek immediate medical care if you have fever and live in an area with malaria or dengue.

FACT-016: Drinking alcohol does not protect you against COVID-19 and can be dangerous

The harmful use of alcohol increases your risk of health problems.

FACT-017: Most people who get COVID-19 recover from it

Most people who get COVID-19 have mild or moderate symptoms and can recover thanks to supportive care. If you have a cough, fever and difficulty breathing seek medical care early - call your health facility by telephone first. If you have fever and live in an area with malaria or dengue seek medical care immediately.

FACT-018: COVID-19 is caused by a virus, NOT by bacteria

The virus that causes COVID-19 is in a family of viruses called Coronaviridae. Antibiotics do not work against viruses. Some people who become ill with COVID- 19 can also develop a bacterial infection as a complication. In this case, antibiotics may be recommended by a healthcare provider. There is currently no licensed medication to cure COVID-19. If you have symptoms, call your health care provider or COVID-19 hotline for assistance.

FACT-019: Can eating garlic help prevent infection with the new coronavirus?

Garlic is a healthy food that may have some antimicrobial properties. However, there is no evidence from the current outbreak that eating garlic has protected people from the new coronavirus (2019-nCoV).

FACT-020: Can shoes spread the COVID-19 virus?

The likelihood of COVID-19 being spread on shoes and infecting individuals is very low. As a precautionary measure, particularly in homes where infants and small children crawl or play on floors, consider leaving your shoes at the entrance of your home. This will help prevent contact with dirt or any waste that could be carried on the soles of shoes.

FACT-021: Can people wear masks while exercising?

People should NOT wear masks when exercising as masks may reduce the ability to breathe comfortably. Sweat can make the mask become wet more quickly which makes it difficult to breathe and promotes the growth of microorganisms. The important preventive measure during exercise is to maintain physical distance of at least one meter from others.

FACT-022: COVID- Corticosteroids (dexamethasone and hydrocortisone) are recommended for severe and critically ill COVID-19 patients.

Corticosteroids (dexamethasone and hydrocortisone) are recommended for severe and critically ill 19 patients under medical supervision. A review of 8 randomized studies with more than 7,000 patients found that the systemic treatment (intravenous or oral) reduced mortality for this group. In contrast, WHO does NOT advise the use of corticosteroids for patients with non-severe  COVID-19, because they may increase the risk of complications or adverse effects.

FACT-023: Can regularly rinsing your nose with saline help prevent infection with the new coronavirus?

No. There is no evidence that regularly rinsing the nose with saline has protected people from infection with the new coronavirus. There is some limited evidence that regularly rinsing the nose with saline can help people recover more quickly from the common cold. However, regularly rinsing the nose has not been shown to prevent respiratory infections.

FACT-024: Studies show hydroxychloroquine does not have clinical benefits in treating COVID-19.

Hydroxychloroquine or chloroquine, a treatment for malaria, lupus erythematosus, and rheumatoid arthritis, has been under study as a possible treatment for COVID-19. Current data shows that this drug does not reduce deaths among hospitalised COVID-19 patients, nor help people with moderate disease. The use of hydroxychloroquine and chloroquine is accepted as generally safe for patients with malaria and autoimmune diseases, but its use where not indicated and without  medical supervision can cause serious side effects and should be avoided.

FACT-025: Vitamin and supplements cannot cure COVID-19

Micronutrients, such as vitamins D and C and zinc, are critical for a well-functioning immune system and play a vital role in mineral promoting health and nutritional well-being. There is currently no guidance on the use of micronutrient supplements as a treatment of COVID-19. WHO is coordinating efforts to develop and evaluate medicines to treat COVID-19.

FACT-026: Clinical trials confirm that hydroxychloroquine does not prevent illness or death from COVID-19

Hydroxychloroquine or chloroquine, a common treatment for malaria and certain autoimmune diseases, has been studied as a preventative treatment for COVID-19. Evidence from these studies shows that hydroxychloroquine has little to no impact on illness, hospitalization, or death.

FACT-027: Are hand dryers effective in killing the new coronavirus?

No. Hand dryers are not effective in killing the 2019-nCoV. To protect yourself against the new coronavirus, you should frequently clean your hands with an alcohol-based hand rub or wash them with soap and water. Once your hands are cleaned, you should dry them thoroughly by using paper towels or a warm air dryer.
