Question 2What specific feature of COVID infections allows it to spread silently from person to person?1 point

The specific feature of COVID-19 that allows it to spread silently from person to person is asymptomatic transmission. This means that people who are infected with the virus but do not show any symptoms can still spread the virus to others. Here are the steps explaining this:

1. A person gets infected with the COVID-19 virus.
2. This person does not show any symptoms of the disease, hence is referred to as an asymptomatic carrier.
3. The asymptomatic carrier interacts with others, breathing out tiny droplets containing the virus.
4. These droplets can be inhaled by people nearby, or they can land on surfaces that others touch and then touch their face, thereby getting the virus into their system.
5. The people who get infected this way may or may not show symptoms, but can also spread the virus further.

This feature makes it difficult to control the spread of the virus, as people who don't know they are infected can unknowingly infect others.
