What is the cause of SARS disease ?
Answers
- SARS is caused by a coronavirus (SARS-CoV) that exists in bats and palm civets in Southern China.
- This infection can be spread easily from close person-to-person contact (such as living in the same household) via respiratory droplets that come in contact with skin or mucous membranes (eyes, mouth, or nose).
Answer:
SARS was a zoonotic disease, meaning it was of animal origin but passed on to humans.
The Centers for Disease Control and Prevention (CDC) note that 75%Trusted Source of emerging infectious diseases come from animals, including rabies and Ebola. Most zoonotic diseases originate in wild animals rather than pets or domestic animals.
Some animals can carry a virus without becoming sick because their bodies are accustomed to the virus. This fact means they are likely to have immunity.
Viruses can change, however. If a virus changes through contact with another type of animal, it can become unpredictable and possibly dangerous.
When a new virus first emerges, people do not have immunity. In time, the immune system develops antibodies for the new virus, and these antibodies equip it to fight the resulting disease.
When swine flu (H1N1) first appeared in 2009, for example, there were concerns that a pandemic could develop. Now, it is one of the seasonal flu strains that pharmacists include in the annual flu vaccine. Many people also have immunity to H1N1.
In 2019, a new coronavirus, which scientists identified as SARS-CoV-2, began making people sick in China. This is the virus causing the current COVID-19 pandemic
