explain how corona virus start its journey human body?
Answers
COVID-19 is caused by the SARS-CoV-2 virus, which spreads between people, mainly when an infected person is in close contact with another person.
The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe heavily. These liquid particles are different sizes, ranging from larger ‘respiratory droplets’ to smaller ‘aerosols’.
Other people can catch COVID-19 when the virus gets into their mouth, nose or eyes, which is more likely to happen when people are in direct or close contact (less than 1 metre apart) with an infected person.
Answer:
The virus that cause COVID-19 spreads primarily through droplets generated when an infected person coughs, sneezes or speaks. You can also become infected by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands.
Explanation:
Yes, some coronaviruses can be transmitted from person to person, usually after close contact with an infected patient, for example, in a household workplace, or health care centre.
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.
