COVID-19 is a severe infectious disease caused by coronavirus (SARS-CoV-2). It is a virus present in animals that are rarely transmitted from animals to humans and then spread person to person.
A person infected with the COVID-19 virus, experiences mild to moderate respiratory problems and sometimes recovers without requiring any special treatment. Older generations and people who have medical problems like cardiovascular disease, diabetes, chronic respiratory disease and cancer show severe symptoms of Coronavirus/COVID-19 causing danger to life.
Currently, there are no vaccines invented or treatments for COVID-19. However, there are researches being done and trials executed to find an exact vaccine.
Causes of Coronavirus/COVID-19:
A infectious virus transferred from animal to human causes coronavirus disease 2019 (COVID-19). Currently we do not know how contagious the virus is. The research has shown that it spreads from person to person if they are in close contact with the infected person (within about 6 feet, or 2 meters).
When a person with COVID-19 coughs or sneezes or talks, the respiratory droplets release into the air inhaling of which the virus spreads into another person. The virus stays on an object for a certain period, if a person touches that object and then his or her mouth, nose or eyes, the virus enters the body. 
Symptoms of Coronavirus:
Symptoms of Coronavirus/COVID-19 range from mild to severe and sometimes asymptomatic. It takes 2-14 days after exposure to the virus, for symptoms to develop.
A person with a weak immune system may develop serious symptoms, like pneumonia. Presently, most confirmed cases are in adults, but some children have been infected.
Most common symptoms of Coronavirus/COVID-19 include:
- A low-grade fever that gradually increases in temperature over time
- A feeling of fatigue and tiredness
- Having a dry cough that gets more severe over time
Other symptoms of Coronavirus/COVID-19 that is seen in few include:
- Shortness of breath
- Aches and pains in the body joints
- Sore throat
- Nasal congestion

These symptoms may become more severe in some people. Also, it is mandatory to call medical services if you or your family have any of the following symptoms:
- Trouble breathing
- Blue lips or face
- Persistent pain or pressure in the chest

COVID-19 Vs The Flu (Influenza):
The COVID-19 and the flu, both are respiratory illnesses that spread from person to person. COVID-19 is caused by the SARS-CoV-2 virus, and the flu is caused by influenza A and B viruses.
Both COVID-19 and flu spread with common scenarios like close contact with infected people and inhaling the droplets spread in air when an infected person coughs. People infected with the flu will experience symptoms within 1 to 4 days while the symptoms for COVID-19 develop between 1 to 14 days.
The symptoms of Coronavirus/COVID-19 and flu range from mild to severe and both can cause pneumonia. COVID-19 is more deadly when compared to that of the flu. Flu is old enough and there are multiple treatments available.
COVID-19 was discovered recently and hence there are no antiviral drugs present yet. Although researches are being done to trial them on infected people. Recovery depends on the strength of the immune system.
- Wash your hands frequently: Wash your hands with an alcohol-based hand wash or with soap and water, regularly and thoroughly. This is necessary because it kills viruses that may be on your hands. Also use sanitizer frequently.
- Social distancing is necessary: Keep about 3 meters distance between yourself and anyone who is coughing or sneezing. When someone coughs or sneezes, small liquid droplets spread into the air from their nose or mouth which may contain virus. And there are chances for you also to get infected.
- Avoid touching your face: Your hands touch many surfaces when you are outside and can pick up viruses. If you touch your face with an unwashed hand, transfer of virus into your body could happen via your eyes, nose or mouth making you sick.
- Practice respiratory hygiene: Make sure you and your family follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately. Use a surgical or any virus protective face mask to cover your mouth and nose while you are outside.
- If you have fever, cough and difficulty breathing, contact your doctor immediately: In case you feel unwell, stay home, do not risk.

Your doctor may also consider testing if you’re at higher risk of serious illness. As a test for COVID-19, a doctor uses a long swab to take a nasal sample. The sample is then sent to a lab for testing.
If you’re coughing, your saliva may be sent for testing. The test results will be available to you in a day or so depending on the available amenities present in your area.

1. I have a cough regularly as I have Asthma. How do I know I am not infected with COVID-19?
A. The cough that is recent and continuous is a clear symptom. This means coughing a lot for more than an hour. If you usually have a cough, it may be worse than usual in case you’re infected with COVID-19.
And if your body temperature increases gradually then you are likely to have COVID-19. It takes five days on average to start showing the symptoms, but some people will get them much later of upto 14 days.
2. A severe symptom of COVID-19 is shortness of breath. What does that mean?
A. Unexpectedly feeling out of breath or difficulty in breathing is how a person experiences shortness of breath. Several other examples of temporary shortness of breath exist that are not the apt symptom.
For example, if you feel very anxious, it’s common to get short of breath which goes away when you calm down. However, recently if you are facing problems with breathing, it is time to call your doctor.
Meanwhile, it’s important to remember that if shortness of breath is your only symptom, without a cough or fever, then it’s something other than COVID-19 that you are infected.
3. Lately I have lost my sense of smell. Have I contracted COVID-19? What should I do?
A. Although lost sense of smell is not listed under the common or severe symptoms of COVID-19, It could be a rare symptom because viral infections are one of the causes of loss of sense of smell, and COVID-19 is caused by a virus.
Studies are being done to get more definitive answers for when a person starts developing loss of smell after he is infected with COVID-19 and how to distinguish loss of smell caused by COVID-19 from that caused by allergies, other viruses.
4. Once I have been exposed to the COVID-19 virus, how long does it take for my body to show the common symptoms?
A. Up until today the research says that on an average, the time from exposure of a person to COVID-19 to the symptom seen (incubation period) is about 5 to 6 days.
However there have been cases wherein an infected person has taken around 13 days to show the symptoms. This has led for all the countries to recommend people to quarantine themselves for 14 days and monitor for symptoms if doubted to be exposed to the virus.
