Understanding COVID-19: Origin, symptoms, and precautions

By Shreyaj Jha

Coronaviruses are a large family of viruses that cause illnesses, ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.

Where was COVID-19 first discovered?

The first known infection of SARS-CoV-2 was discovered in Wuhan, China. The original source of viral transmission to humans remains unclear.

Symptoms

Some of the primary symptoms to look for in a COVID-19 infected person are fever, dizziness, breathlessness, headache, dry cough (which may eventually result in phlegm), and, in a few cases, loss of smell and taste. A few cases have also reported diarrhea and fatigue.

Precautions

Some of the immediate precautionary measures that one took was:

Maintaining a safe distance from others (at least 1 meter), even if they don’t appear to be sick.

Wearing a mask in public, especially indoors or when physical distancing is not possible.

Choosing open, well-ventilated spaces over closed ones or opening a window if indoors.

Cleaning your hands often. Use soap and water or an alcohol-based hand rub.

Getting vaccinated when it’s your turn. Follow local guidance about vaccination.

Covering your nose and mouth with a tissue when you cough or sneeze.

Staying home if you feel unwell.
