Check out how you exactly catch Covid-19:
It’s been six months that we are dealing with a coronavirus pandemic and there is still a question that persists: How do people become infected?
It’s not common to contract Covid-19 from a contaminated surface, scientists say. And fleeting encounters with people outdoors are unlikely to spread the coronavirus.
The major form of transmission is the person to person interactions for extended periods. Crowded places, poorly ventilated areas, and places where people talk loudly have the maximum risk. These findings are helping businesses and governments to determine reopening strategies to protect people.
Two major studies show that wide-scale lockdowns have prevented millions of infections and deaths around the world. Now, with more knowledge in hand, cities and states can deploy targeted interventions to keep the virus from taking off again, scientists and public-health experts said.
How do we get Covid-19?
There are three ways of getting Covid-19 virus:
Coughing, talking and breathing creates virus-carrying droplets of various sizes
Enough virus has to make itself over to you to build up around you over time to trigger an infection.
The virus has to make its way into your respiratory tract and use the ACE-2 receptors there to enter cells and replicate.
One major thing in the transmission is that activities like speaking and breathing produce respiratory bits of varying sizes that can disperse along air currents and potentially infect people nearby.
Health agencies have so far identified respiratory-droplet contact as the major mode of Covid-19 transmission. These large fluid droplets can transfer the virus from one person to another if they touch the eyes, nose, or mouth. But they tend to fall to the ground or on other surfaces pretty quickly.
Some experts say the new coronavirus can also be transmitted through aerosols or minuscule droplets that float in the air longer. These aerosols can be directly inhaled.
That is why we need to cover our mouth and nose with a mask. And proper ventilation is required. Regular cleaning is also recommended.
Stay safe, stay protected.
