- ensuring good air ventilation to reduce chances of getting the virus
The person giving care should make sure they limit contact, as much as possible, with the individual they are caring for.

Coronavirus typically spreads via small water droplets that a person with the virus produces when they talk, cough, or sneeze. When another person inhales these droplets, the SARS-CoV-2 virus can enter the body.
Droplets in the air can also land on surfaces and objects. People who touch these contaminated surfaces are at risk of infection if they then touch their eyes, nose, or mouth before washing their hands.
Some people may transmit the virus despite being asymptomatic. However, researchers do not know
