Although more than two years have passed since the advent of Corona and the achievements of scientists in producing vaccines and providing treatment, but this emerging virus has many secrets and mysteries that have so far left unanswered questions.
The first question is how the virus evolved. When the Delta variant appeared, it acted as an effective distributor, to the point that some speculated that the virus was approaching its maximum transmission potential. The omicron then appeared, one of the most transmissible mutations we have ever seen, according to the Middle East newspaper.
The Omicron was different from the alpha and delta types that dominated the world, ignoring the expectations of experts who thought it would be of any concern to their descendants. .
“While we all have Omicron and BA, “We are watching. 2 minor mutations, another development may be on the way.” “We do not know him yet.”
From this question of how the corona develops, to another question raised in this report, “What is the shape of the infection waves in the future,” what we have seen so far shows that by increasing people’s immunity to the virus, through vaccination or infection Or both, we are less likely to become infected.
If an injury occurs, it is not serious and will not lead to death. This prompted scientists to wait for the virus to calm down, but at the same time confirmed that the virus has not become a native virus like the flu, so its appearance is seasonal and the wonders are still in place.
Other questions that need to be answered are: “How worried should you be if you have not been infected before?”
Research has shown that people who become infected with the virus and then receive the vaccine have good immunity, that is, they produce higher levels of the immune cytokine called “interleukin 10”, and it is not clear whether the same effect occurs in them. Or not. People who have been vaccinated or not, and then become infected with Superinfection (virus infection despite vaccination).
Regarding the fourth question, which Virginia Tech announced last March about an $ 8 million project to get the exact answer, how exactly does the virus spread from person to person? Studies have shown that infected surfaces are rarely responsible for transmitting the virus, as it is transmitted mainly through streams of invisible respiratory particles emitted by each person while talking, singing, sneezing, coughing and breathing.
The virus can survive even in the smallest particles called aerosols, which can stay indoors for hours and be inhaled in the deepest recesses of a person’s lungs. But exactly how much COVID-19 in airborne particles can cause infection? This question has remained unanswered so far.
In a study published in January, Vincent Munster, head of the viral ecology department at the National Institute of Allergy and Infectious Diseases in the United States, and his research team showed for the first time that the smallest aerosols, less than 5 microns in size, are emitted by hamsters. , Contained enough virus to infect hamsters. Others are not hamsters at 6 feet after just one hour, and that question still needs to be answered.
In addition, with the advent of new types of viruses, the fifth question arises: Will we receive a new and better generation of vaccines? Although there are still reassuring messages about the effectiveness of current vaccines, at least in protecting against severe diseases, the reality is that work needs to be done on vaccines that offer much broader immunity to the new Covid-19 strains.
The World Health Organization tracks more than 150 different vaccines for Covid-19 at various stages of testing, but their path to market may not be quick or easy unless we are convinced of the importance of this process.
The sixth and final question is: What are the causes of what is called the long-term Covid-19? Almost everything remains a mystery about the long-running mystery of the Quaid symptoms, but scientists have finally come up with what might be called “bread crumbs” to find the root cause of the symptoms.
Scientists in many specialties treat a set of symptoms that remain in one-third of people after infection. Virologists specialize in HIV coronavirus, neurologists try to explain the cognitive and physical abnormalities seen in rehabilitation clinics, and immunologists examine inflammatory and autoimmune responses.
Scientists have also put forward three possibilities that may be responsible for the long Covid-19, and they have not yet decided on the correct possibility of describing what is happening. One of these possibilities is related to what is known as “autoimmunity”. The body begins to attack after infection.
The second possibility is “chronic inflammation”, which means a continuous and superior response to infection, and finally there is the possibility of “viral persistence”, due to which the virus is still lurking in hidden reservoirs after the body. Resistant to acute infection.
