**6. Spread of the virus**

With highly changeable symptoms, COVID-19 ranges from none to fatal ailments. The virus of this illness is said to travel through the air from person to person nearby. Once an infected person coughs, breathes, or speaks, the virus is released and attacks the person next to him. It is also very likely to spread through surfaces already contaminated by virus-affected patients. The duration of this virus is at least 14 days, and it has the potential to spread asymptomatically as well (**Figure 3**).
