The general diseases humans and animals suffer from can be divided broadly into bacterial infections and viral diseases. As the name suggests, viral diseases are caused by microbes known as viruses and tend to be of a highly infectious nature.
What are the Most Common Ways in Which Viral Diseases Spread?
As said earlier, viral diseases are some of the most contagious diseases around. However, not all viral diseases spread the same way. Some of the most common ways in which viruses multiply and spread from person to person are -
- Breathing in contaminated airborne droplets.
- Drinking liquids or eating food contaminated by viruses or used by a patient suffering from viral diseases.
- Having a sexual relationship with a person suffering from sexually transmittable viral diseases.
- Indirect transmission of the virus through ticks, mice, and mosquitoes.
- Coming in contact with body fluids of a virus-infected person or touching surfaces contaminated by the virus.

Sars coV-2 or Coronavirus or COVID-19
Coronavirus is a highly contagious disease caused by a virus named SARS coV-2. The disease is spread by droplets passed on from the infectious person when they speak, sneeze, cough, or even breathe. The COVID-19 disease started in Wuhan, China, in late 2019 and has engulfed the globe ever since in the form of a raging pandemic.
The persons infected with coronavirus generally suffer from mild to moderate symptoms that can well be tackled at home under strict isolation. However, those who become seriously ill might require intensive care at the hospital, including an artificial respiratory support system.
Ever since this viral disease was discovered, the WHO has been asking people to wear N95 or surgical masks outdoors, maintain a two-meter distance from others, and restrict outdoor movement as much as possible.
