American medical experts are puzzled by reports of Covid-19 patients having different side effects or after effects months after they have been diagnosed with the infection.
Dr. Francis Collins, chief of the National Institutes of Health that they are faced with a mystery. Many questions have to be answered and the scientists are proceeding forward as Collins’ institute is designing studies to follow more than 20,000 people who have recovered from COVID-19 but face weird symptoms to date.
The common and uncommon symptoms faced by many include the following:
- Shortness of breath
- Organ damage — lung scarring and heart inflammation
- Blinding headache
- Burning lungs
- Rapid heartbeats
- Dizzy spells
- No taste or smell
- Brain fog
- Nagging smell of something burning
- Ringing in the ears
Researchers are hoping that studies on the long-term effects of COVID-19 may shed light on other diseases such as chronic disease syndrome and Lyme disease.
The working theories that have been proposed for symptoms that are appearing in long haulers are as follows:
- The virus stays in the body at very low levels and causes tissue or organ damage
- The virus overstimulates the immune system which stops the body’s return to its pre-Covid state
- The virus attacks blood vessels which in turn lead to minuscule blood clots that harm the body
Some scientists believe than one or all three of these theories are the probable cause for different symptoms.
However, some experts also say that the lockdown, the change of normal routine and the new normal could have affected some patients.
Others say that some of the “long haulers” may have had detected or undetected underlying conditions that could have caused many of these symptoms.
COVID-19 is a new, twenty-first century disease and scientists have to grapple with a lot and conduct long-term research to find answers to many baffling questions about the coronavirus and not only weird symptoms.
