One In Three People With Covid 19 Develops Symptoms For Months, And Scientists Are Trying To Understand The Cause And Treatment.
Most people with coronary artery disease have common symptoms of fever, cough, and respiratory problems that improve within a week or two. However, some people, who are estimated to make up 10 to 30 percent of Covid patients, develop persistent symptoms called “long Covids” in conversational conversations.
Why do some people recover so quickly? While the symptoms of others last for months? This question is one of the difficult questions related to Pandemic Covid 19 ‘s. Although there is no definitive answer yet, researchers around the world have suggested several theories on the subject. What lessons have we learned so far about Covid and what does the latest evidence show?
What is a Long Covid?
There is no universally accepted definition for a long Covid; Because it is a new phenomenon. Practically, long covid is a term used to describe a condition in which people experience a range of persistent symptoms after covid.
The most common symptoms we ( Lewis Holmes and Alex Irving, authors of The Conversation website ) hear from people with long Covid at our long Covid clinic in Melbourne are fatigue, shortness of breath, chest pain, palpitations, headache Brain, muscle aches, and sleep disorders.
However, long cavitation can also include a wide variety of symptoms, such as loss of sense of smell and taste, depression, and inability to do work and interact with the community.
In some people, it seems that there is a process that affects all parts of the body.
Another feature for many people is the lack of a link between the severity of early Covid disease and the development of important and lasting symptoms in the healing process.
Most of our patients at the Long Covid Clinic had a milder illness at first, and most of them were younger than the hospitalized and healthy and active before the Covid. Many of our patients are concerned about the existence of permanent infection and injury and are afraid that they will not recover.
So far, we have not found a specific test to explain the post-Covid symptoms. This confirms our view that in most patients, the symptoms of prolonged cavitation are likely to be related to the complex interaction between physical and psychological processes that occurs after the sudden onset of inflammation due to cavitary infection.
What is the prevalence of long Covid?
It is very difficult to determine the proportion of people with Covid who eventually develop persistent symptoms. At this stage, we do not know the exact rate. In an ongoing study on Covid’s safety at the Walter and Eliza Hall Institute in Australia (WEHI), we found that 34% of participants were still involved in prolonged Covid for 45 weeks after diagnosis; However, our study is community-based and is not designed to measure the overall prevalence of this condition in a larger population.
Data on the prevalence of long quadruplets are gradually being disseminated, with different sources reporting different rates.
The rate obtained depends on how the researchers used and followed the study participants.
For example, are the results of the follow-up of patients after discharge from the hospital or based on community-based surveys?
The World Health Organization estimates that the prevalence of long-lived Covid is 10 percent; While a study from the UK obtained a figure of 30%. The proportion of people with this condition probably varies from country to country.
Many doctors still do not know about Covid 19; Therefore, many cases may be diagnosed and not added to the study. In fact, after some of our data was broadcast on a program on ABC Australia, more people with persistent symptoms came to join our study, and some of them did not know if such research was being done or even if it existed.
To determine the approximate rate, we need a thorough demographic study. This means contacting a whole group of people who have had cavities, and examining how many of them are experiencing ongoing problems at a given time, such as a year later. This type of study is difficult to do, But that means we can answer an important question.
How is long Covid treated?
This condition is difficult to treat because of this, and there is still no standard treatment that does not have a definitive clinical trial to determine if a person has it. People with mild symptoms may not need treatment; They just need confirmation and information. Others who have more severe or persistent symptoms need more help.
By providing clinical care with the support of a coordination team of specialists in a variety of fields, Covid Long Multidisciplinary Clinics ensure that patients receive the best available treatment without the endless burden of multiple independent consultations. These clinics use a comprehensive approach and use the best-known strategies to support the patient’s recovery.
For most people, the results are promising. After nine months, half of our patients were close to normal and discharged from the clinic. Meanwhile, there is a group of patients whose progression is slower. They were often young and had previously performed well; But after the illness, their ability to work, exercise, and socialize has weakened.
Their return to work and other activities should be carefully managed and they should not do too much work immediately. The persistent symptoms of these patients must be recognized and supported by the family, the employer, and the multidisciplinary medical team.
What causes long Covid?
We still do not know why some people get long cavities; While others recover within a few weeks of becoming infected. If the long queue was easily associated with the strong queue, it would give us clues; But this is not the case, and we have seen that people with mild illnesses eventually experience long-term symptoms; Just as people in intensive care may do.
Theories put forward about the cause of long Covid
There are several theories about the cause of the long Covid, the most important of which we will mention. According to one theory, prolonged cavitation could be the result of an immune system malfunctioning and overactivity due to infection.
A clue that supports this theory is that some people with prolonged Covid say that their symptoms will improve dramatically after receiving the Covid vaccine. This strongly suggests that the various symptoms of long quadriceps are related to the immune system.
The Covid 19 vaccine may redirect the immune system to its normal pathway by directly activating certain immune cells, such as T cells, which help stimulate antibody production and kill virus-infected cells, or innate immune frontline cells, which modify this immune disorder. , Help improve symptoms.
Another theory is that patients with long cavities have small, stable virus reservoirs that cannot be detected by diagnostic tests, or that small pieces of the virus remain that the body has not been exposed to.
These tanks are not infectious, But they may activate the immune system continuously.
The vaccine may help guide the immune system to the right position and clear the remaining viruses.
Although we still can not say for sure that the vaccine will help everyone, no evidence boosting the immune system with the help of the vaccine may make things worse. Of course, the long Covid may be the result of a combination of the two or different elements.
The bottom line is that we still need more research. There is no cure yet, But we can manage and support the symptoms of those infected and encourage everyone to get the Covid 19 vaccine as soon as it is available.
