Who is likely to be infected with coronavirus ?
Most people infected with the COVID-19 virus will experience mild to moderate respiratory symptoms and recover without needing special treatment. However, older people, and those with underlying medical conditions like cardiovascular disease, diabetes, chronic respirat ory disease, and cancer are more likely to develop serious symptoms when infected with the virus.
How coronavirus spread ?
Data from epidemiology and virologic studies provide evidence that COVID-19 is primarily transmitted from symptomatic people to others who are in close contact through respiratory droplets, by direct contact with infected persons, or by contact with contaminated objects and surfaces.
When an infected person coughs, sneezes, speaks or breathes the droplets from them form in a wide range of sizes, but the tiniest ones, called aerosols, can easily slip through the openings between certain cloth fibers. In other words, respiratory droplets can be of various sizes and are commonly classified as aerosols (made of droplets that are <5 μm) and droplets that are greater than 5 μm. The fate of these droplets largely depends on environmental factors such as humidity, temperature, etc. While the larger droplets settle due to gravity and do not travel distances more than 1–2 m, aerosols remain suspended in the air for longer durations due to their small size and play a key role in spreading infection.
