Share the article

Coronavirus has taken over the world. Lockdowns are in place in nearly every part of the globe, but the relentless march of the virus continues unchecked. If we have to know how to stop it, we should first know how it spreads.

COVID 19 infection

COVID19 is caused by a new virus the SARS-CoV-2. It causes respiratory tract infection, an infection of the upper respiratory tract (sinuses, nose and throat) or lower respiratory tract windpipe and lungs.

Most common symptoms of COVID 19 include:

  • Fever
  • Dry Cough
  • Fatigue
  • Sore throat
  • Difficulty in breathing
  • Loss of appetite

COVID 19 spreads in many ways

COVID 19 is one of the fastest spreading infections. It spreads from person to person easily in the following ways.

Through respiratory droplets

When an infected person coughs, sneezes or talks, droplets carrying the virus are sprayed into the air from their nose or mouth. If you are within 6 feet of that person, you will inhale theses and get infected.

Aerosolised transmission

Latest research shows that the virus can linger in the air in an aerosolized form for nearly three hours. When you breathe this air, you will be infected.

Surface transmission

When a person with the virus coughs or sneezes on a surface and you touch the surface and touch your face, nose or mouth, you will be infected.

Fecal spread

The virus is present in the stool of infected persons. When they use the bathroom and do not wash their hands properly they can transmit the infection to people they touch.

Asymptomatic and presymptomatic spread 

Many people who infected with the virus do not show any signs or symptoms of the disease. They are said to be asymptomatic. In other infected people, the symptoms may take a while to develop, but will develop into disease. They are said to be in the presymptomatic stage.

Both Asymptomatic and Presymptomatic people can spread the infection.

Easy methods of COVID 19 prevention

  1. Wear a mask when you step out of your home
  2. Stay at least 6 feet away from people when you go out
  3. Wash your hands with soap and water for 20 seconds
  4. Avoid unnecessary travel
  5. Stay home, stay safe

If you suspect you have COVID infection, call the national or state helpline, or call your doctor for guidance.
