Some people are asymptomatic. This means they have the coronavirus but their bodies are able to control the infection in a few days and they have mild or no symptoms.

Those who are at a higher risk of serious illness or death if they get infected by the coronavirus are usually called at-risk or vulnerable.

This includes people over 70 and those with underlying medical problems like heart disease, high blood pressure, diabetes, chronic respiratory disease, cancer and recent organ transplants.

They should stay at home and avoid other people. Those with weak immune systems are also more at risk of serious illness.

Stress, a poor diet, not being able to absorb certain nutrients, drinking too much alcohol, tiredness, and a lack of rest can all weaken your immune system. You may be more easily exposed to the coronavirus when you are in this state. Don’t assume you are not at risk of a serious infection.

Treatments for rheumatoid arthritis, lupus, multiple sclerosis, inflammatory bowel disease also lead to a weaker immune system.

If you are close to vulnerable or at-risk individuals then always be responsible and take all precautions to avoid catching and spreading the virus.
