COVID-19: COVID-19 is a new disease, caused by a novel (or new) coronavirus (SARS-CoV-2) that has not previously been seen in humans. There are many types of human coronaviruses including some that commonly cause mild upper-respiratory tract (sinuses, nasal passages, pharynx and larynx) illnesses. In COVID-19, ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ ‘D’ for ‘disease’ and ‘19’ for ‘2019.’
HOW COVID-19 SPREADS
How does COVID-19 spread?
People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets coming from the nose or mouth when a person with COVID-19 coughs or breathes out. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, and then their eyes, nose or mouth. People can also catch COVID-19 if they breath in droplets from a person with COVID-19 who coughs out or breathes out droplets. This is why it is important to stay 3-6 feet or about 1-2 meters away from a person who is sick.
Can COVID-19 be caught from a person who has no symptoms?
People are most likely to spread the disease when they have the symptoms, that is, “symptomatic” or sick. This is because the main way the disease spreads is through droplets expelled by someone who is coughing or sneezing. However, it is possible that some spread can happen before people show symptoms. Social distancing is recommended even for people without symptoms.
Can someone who has been quarantined for COVID-19 spread the illness to others?
Quarantine means separating a person or group of people who have been exposed to a contagious disease but have not developed illness (symptoms) from others who have not been exposed. The purpose of quarantine is to prevent the spread of that disease. A person exposed to similar coronaviruses as the COVID-19 virus usually develops an illness within 10 days of exposure. Because of this, a person who might have been exposed to the virus from another infected person should quarantine themselves for a period of 10 days. During this period, they can develop and/or spread the illness to others. Beyond the quarantine period, the person is considered to be not at risk of developing or spreading the illness.
Can the virus that causes COVID-19 spread through drinking water?
The virus that causes COVID-19 has not been found in drinking water. Conventional water treatment methods that filter and disinfect the water should remove or inactivate the virus that causes COVID-19.

Can COVID-19 be spread through food?
Coronaviruses are generally thought to be spread from person-to-person through respiratory droplets. Right now, there is no evidence to support the spread of COVID-19 through food. Before preparing or eating food it is important to always wash your hands with soap and water for 20 seconds for general food safety. Throughout the day wash your hands after blowing your nose, coughing or sneezing, or going to the bathroom.
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.
In general, because it is hard for COVID-19 to survive on surfaces for long, there is likely very low risk of spread from food products or packages that are shipped over a period of days or weeks at room temperature or refrigerated or frozen temperatures.
Is it safe to receive a package from any area where COVID-19 has been reported?
Yes. It is unlikely that a person with COVID-19 will infect the contents of a package. Since packages are moved and exposed to different conditions and temperatures, it is also unlikely that people will catch COVID-19 from the outside of a package. However, it is advised to wash your hands with soap and water for at least 20 seconds, after touching objects handled by other people.
SYMPTOMS, TESTING, TREATMENT
What are the symptoms of COVID-19?
The main symptoms of COVID-19 are fever, cough, and shortness of breath or difficulty breathing. Other symptoms include repeated shaking with chills, muscle pains, headache, sore throat and new loss of taste or smell.
Those who are ill may also have fatigue (tiredness), nasal congestion (stuffy nose), or diarrhea; however, many people who become infected do not have any symptoms. Most people who get COVID-19 get better without needing special treatment. However, some become very ill. Please talk to your doctor about any other symptoms that are severe or concerning to you.
Are the symptoms of COVID-19 different in children than adults?
No. The symptoms of COVID-19 are similar in children and adults. However, children with confirmed COVID-19 have generally shown mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher risk for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.
Who needs to be tested for COVID-19?
Anyone with symptoms should be tested, wherever possible. People who do not have symptoms but have had close contact with someone who is, or may be, infected may also consider testing – check your local health guidelines and follow their guidance. If you are having symptoms and feel you need to be tested, if at all possible, reach out to a medical provider by phone before seeking care in person.
While a person is waiting for test results, they should remain isolated from others. Where testing capacity is limited, tests should first be done for those at higher risk of infection, such as health workers, and those at higher risk of severe illness such as older people, especially those living in seniors’ residences or long-term care facilities.

What should I do if I think I am sick?
If you think you have been exposed to COVID-19, you should stay home and stay away from others as much as possible. If you are sick and develop a fever and symptoms, such as cough or difficulty breathing, call your healthcare provider for medical advice. Many people will be able to recover at home; however, be sure to get care if you think it is an emergency. If you seek care, call ahead to make sure they know you may have COVID-19 so that healthcare workers can protect themselves.
HOW TO PROTECT MYSELF AND MY FAMILY
What steps can my family take to reduce our risk of getting COVID-19?
Practice everyday preventive actions to help reduce your risk of getting sick and remind everyone in your home to do the same. These actions are especially important for older adults and people who have chronic medical conditions:
- Avoid close contact with people who are sick.
- Stay home when you are sick, except to get medical care.
- Wear a face cover or mask.
- Cover your coughs and sneezes with the inside of your elbow or a tissue and throw the tissue in the trash. Then wash your hands.
- Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before cooking or eating.
- If you do not have soap and water, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
- Clean and disinfect surfaces and objects that people touch a lot (e.g. phones, other electronics, tables, countertops, light switches, doorknobs, and cabinet handles).
- Get vaccinated.
Is there a vaccine for COVID-19?
Two vaccines that have been granted emergency use authorization by the Central Drugs Standard Control Organization (CDSCO) in India are Covishield® (AstraZeneca’s vaccine manufactured by Serum Institute of India) and Covaxin® (manufactured by Bharat Biotech Limited).
Please visit our Vaccine FAQs page for more information.
Should I use a facemask or face cover to prevent COVID-19?
You should cover your mouth and nose with a cloth face cover when you are out in public, for example while going to the grocery store. This is to protect others and yourself from the risk of getting COVID-19, since one could spread the virus to others even if they do not feel sick.\
The face cover should cover the mouth and nose completely. Face covers must not be shared, and each person should have their own face covers. It is useful to have two sets of such face covers so one can be washed while the other is used.
Cloth face covers should not be used by people who have trouble breathing, or children under age 2 years, or people who are unable to remove the mask without help.
The cloth face cover is not a substitute for social distancing. You should continue to keep 6 feet between yourself and others. Hand washing is still very important, and hands should be washed before wearing the face cover.
A triple layered medical/ surgical face mask is specially recommended for people who have COVID-19 and/or are showing symptoms and their caregivers.
Please watch this video by the WHO to learn how to properly fit your mask:
- The following document has information on how to make your own face cover (page 5-12), how to wear a face mask (page 9 and 12), how to clean, disinfect and store your face covers (page 13-14): https://www.mohfw.gov.in/pdf/Advisory&ManualonuseofHomemadeProtectiveCoverforFace&Mouth.pdf
What does it mean to practice ‘social distancing’?
- Keeping your distance from others (6 feet or 2 meters away).
- Not taking public transportation, taxis, or ride-shares during this period.
- Avoiding crowded places (for example: shopping centers, schools, workplaces, movie theaters, and places of worship such as temples, churches, synagogues, and mosques).
How should I clean and disinfect my home in order to protect myself and my family from COVID-19?
On a regular basis, clean and disinfect frequently touched surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.
After cleaning and disinfecting, clean your hands with an alcohol-based hand sanitizer or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

Who is at risk for serious complications from COVID-19?
People of all ages can become infected with COVID-19, but some people are at higher risk of getting very sick from this illness. This includes:
- Older adults
- People who have underlying chronic medical conditions like heart disease, diabetes, lung disease
This does not, however, mean that other groups won’t fall sick or are immune from it. Everyone is at risk; some more than others.
Are people with disabilities at higher risk for COVID-19 infection or severe illness?
Most people with disabilities are not inherently at higher risk for becoming infected with or having severe illness from COVID-19. Some people with physical limitations or other disabilities might be at a higher risk of infection because of their underlying medical condition.
You should talk with your healthcare provider if you have a question about your health or how your health condition is being managed.
