Danger! Beware of these 4 conditions that may occur to your parents after COVID-19

On the first day after infection, there may be nothing unusual in your parents' bodies. At this time, the virus has just invaded the respiratory tract and is still secretly multiplying, preparing to cause trouble.

On the second day after infection, many young people will start to have a fever, which means that the immune system has officially started a war with the virus. However, middle-aged and elderly people like parents may not have a fever and still have no obvious symptoms. They will only have more hidden symptoms, such as lethargy, loss of appetite, chest tightness and shortness of breath, etc.

On the third day after infection, the virus may have quietly invaded the lungs, causing a decrease in blood oxygen levels and tissue hypoxia. Silent hypoxia in middle-aged and elderly people may appear calm on the surface, but the blood oxygen level may have dropped below 70%, which is very dangerous.

On the fifth day after infection, the disease should normally be in its final stages, but for middle-aged and elderly people, especially those with underlying diseases, the symptoms may be more serious. If they are found to have obvious symptoms of shortness of breath around 5 days after infection, it is best to go to the hospital for a lung CT scan to see if the lung infection is serious.

Of course, it is not just after testing positive, what is more important is daily protection and nutritional supplementation is also very important.
