Enduring effects of COVID
Medical research has become well aware that all viral infections can lead to chronic illnesses involving many vital organs and systems.
In this article 2 main residual effects of COVID-19 were investigated.
The obvious place to check for long-term harm is in the lungs, because COVID-19 begins as a respiratory infection and can be for those at risk the main cause of death.
The lungs’ main purpose is transferring oxygen into the blood and removing carbon dioxide. Secretions from the body’s attempt to fight infection prevents oxygen transfer. The continued shortness of breath, one of the main symptoms post COVID-19, ensured 13.5% of sufferers were still using oxygen at home, at 2 months post COVID-19.
Evidence from people infected with other coronaviruses suggests that the damage will linger for some months.
COVID-19 often strikes the lungs first, but it is not simply a respiratory disease, and in many people, the lungs are not the worst-affected organ.
In part, that’s because cells in many different locations harbour the ACE2 receptor that is the virus’s major target, but also because the infection can harm the immune system, which pervades the whole body.
Some people who have recovered from COVID-19 could be left with a weakened immune system.
The virus can also have the opposite effect, causing parts of the immune system to become overactive and trigger harmful inflammation throughout the body. There is widespread inflammation and organ problems.
