What’s COVID-19?

Coronaviruses are a large family of viruses which may cause illness in animals  or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

 

Symptoms of COVID-19








The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell.






















Route of transmission

Through air: mostly with the forms of droplets spread from man to man. Through touching: hand-mucosa (eyelid, nasal cavity, oral cavity).

Through wild animal: directly contact with wildlife.


Incubation period for COVID-19

The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days.
