Why does COVID last longer?Experts explain the position of research

As you may know, getting infected with COVID is different from the typical cold of staying in bed for a few days and then returning to work without anything. It can hit you flat for weeks or have symptoms that last long after you test for negative again.Researchers are beginning to think of a theory as to why Some COVID cases are long lasting..Until 87% continue to experience some symptoms More than a month after COVID infection, according to an Italian study published in JAMA In July. For some, COVID symptoms last for a long time, months after the initial worrying cough and loss of odor. For others, the symptoms of COVID come and go, even if they feel they have recovered.

“There is new evidence that some people with COVID infections have longer-lasting symptoms than expected.” Dr. Daecheong MD, Johns Hopkins, an assistant professor of physical therapy and rehabilitation in medicine, tells Bustle.

Average time From COVID infection to symptoms According to Harvard Health, it’s about 3-14 days, and Johns Hopkins Health usually has these symptoms. Lasts about 1-2 weeks In mild cases. From start to finish, many people will be on the COVID train for three weeks to a month, but others will feel good just to be bedridden for years or to go to bed due to recurrent symptoms. Become. “Long distance” COVID.. Doctors are just starting to invade when it comes to understanding why the symptoms of COVID decide to continue.

Why COVID cases last so long

There are several theories as to why some COVID cases can cause someone to feel offended for weeks or even months. Generally speaking, Mild COVID symptoms vary widely from person to person —Therefore, the COVID experience can last for years while the roommate stands up and kicks a few days after the positive diagnosis.The World Health Organization said in September that many people, even those with mild illness, Experience “prolonged” symptoms Prolonged recovery makes it less infectious, but still makes you feel terrible.

If you have a bad COVID case, Recovery may take 6 weeks or more, Johns Hopkins Health says.. Nature Reported in September Severe COVID can cause long-term damage to the lungs and other organs.. However, even in mild cases, symptoms can worsen.Studies published in PLoS One I found it in November Persistent fatigue, feeling unable to even get out of bed, It is very common among people who have been infected with COVID and occurs in about 52% of people. This has nothing to do with the severity of the original infection.

It’s not clear why some people have mild COVID symptoms that disappear like clouds on a sunny day, while others feel rotten for weeks.Study of people with mild to moderate COVID infection Clinical microbiology and infectious diseases I found it in october Up to 60% of cases were symptomatic after 2 months They caught it first.The authors suggested that this might have something to do with it Inflammatory reaction.. Inflammation is the body’s response to injuries and threats, so if the body reacts to a COVID infection and a large-scale inflammation recurs, it may take some time for the symptoms to disappear.

“This is actually emerging as a very serious health problem,” says Dr. Chung. “It can be very debilitating.”

COVID long haul researchers have many questions

Long-distance COVID, It is another problem that symptoms continue to appear months after the initial infection and recovery. Nature Reported in September, some people may experience high levels of inflammation in the months following COVID diagnosis, which Long-term symptoms or damage to the immune system with time. However, there is not enough information yet to confirm this.

There are many theories about long COVID. “If you listen carefully to their symptoms, they sound very good. POTS, or Postural Tachycardia Syndrome“There is a suspicion that long-haul carriers may have POTS or other types of autonomic dysfunction.” POTS is a blood circulation disorder that causes dizziness and abnormal heart rate, which is Often diagnosed after a viral illness..Also More common in women than in men..

Dr. John Cerrick, Jacobs Medical College at Buffalo University and a professor of medicine at the Faculty of Biomedical Sciences, many doctors have long COVIDs As a result of an excessive immune response But that has not been confirmed. “One of the obvious things is that the infectious virus is gone, so no specific antiviral treatment is needed.”

COVID too Stay in the “pocket” of your body The BBC reported in October, long after most of it was expelled by your immune system.Studies published in Nature Neuroscience In December Coronavirus peaplomers (small superficial spines) help invade the brain.. If it hangs even a little there, it can cause long-term problems such as brain fog and can interfere with the respiratory center of the brain, which helps control breathing.Studies published in Lancet Some people with COVID in August It actually shows changes in the structure of their brain, This can explain why some symptoms last so long.

Now i have Needs detailed study of long COVID To help doctors understand why some people have long-lasting symptoms and what they can do to do so. COVID-19 patient-led study While conducting a survey of other COVID patients Clinic opened at the University of California, Davis Especially to study the condition.. Many survivors of long COVID Unite to support group Around the world, they will be waiting for a definitive answer about what is really happening.
