Immunity or immune system against the coronavirus (covid-19)

Immunity or immune system against the coronavirus (covid-19)

A few countries are beginning to ease the restrictions and return to work. but plans for reopening are based on limited information and vaccine predictions. It is still unclear if covid-19 patients are found to have a long-term immune system (Immunity) and the tests used to determine infection remain intact.

Do recovered patients develop immunity?

Infection Trigger Email Responses to the Human Body- Production of antibodies able to fight off germs. the immune system (immunity) reminds itself of the germs once they are exposed to it, so the body is ready to fight it in the future.

The body may develop lifelong infections in other diseases such as poultry, but temporary communities in flu-like diseases are the common cold. it is resistant to several infections but the body cannot form any vaccine, as in the case of HIV. It is not yet entirely clear when SARS-CoV-2 causing covid-19 falls within this framework of resistance. The duration of insecurity depends on how much the immune system (immunity) remains in the body and how effective it is in contracting the disease.

Studies conducted on Sar, another type of coronavirus, revealed that the antibodies lasted about 2 years but there was no guarantee against re-infection.

Early studies suggest that access to new coronavirus grants is at least a yearly defense. Studies say that after covid-19 infection most people develop an immune response system (immunity) that will provide some protection over a period of at least a year when its effectiveness may be reduced.

If the virus is unable to understand and the existing antibody cannot function properly it is a presumption that the virus is not mutated. If we get infected now and come back next February, this person will be protected.

How do you decide not to become infected?

Serological tests are used to determine the amount of antibodies present in blood samples, which may give an indication of future infection risk. At the very least, the presence of antibodies to a specific disease confirms that a person is infected with the weather or has shown no signs.

Commercial assessments are available in the market, even though many regulators around the world do not trust their accuracy. Even very high quality tests can show false positives, pointing out the missing antibodies and false positives that ignore the existing immune system (immunity). Inaccuracy in testing is a problem given that many countries issue vaccine certificates using these test results.

What are the limitations of testing for antibodies?

While serological tests detect the presence of antibodies, they do not tell us what level of the immune system is sufficient to prevent infection or how long the antibodies will last and the presence of antibodies does not guarantee that one cannot transmit the virus to others. Disputes do not all immune systems are created equal.

Only so-called neutrals reduce or prevent infection by binding the virus. Some types of antibodies recognize the pathogen but are not bound to it. Some experts have warned against using tests of antibodies to determine policies until they know of a portion of covid-19 Survivors producing inactive antibodies.

Why some of us might have better protection (immunity) against the coronavirus (covid-19) than others

Can sex hormones hold the key to treating coronavirus?

Data from around the world show that women are less likely than men to get covid-19 cases and are much more likely to recover. Some experts believe that hormones produced in large quantities are female estrogen and may be an explanation.

While estrogen affects the ACE2 protein, which is used by coronavirus to attack cells, progesterone is known to have anti-inflammatory properties that also suppress the immune system (immunity). This is made easier by pregnant women who have been tested for HIV even though they have not been vaccinated.

Because of this, scientists in the US who are undergoing hormone testing can help treat patients. Hormones are safe to use for a short period of time but can cause side effects that may be uncomfortable for men, possibly breast tenderness and hot flashes.

However, experts say there is not enough evidence to support hormone therapy yet. Data shows that older women with lower levels of hormones are more likely than older men to recover. women are at lower risk and will be exposed to other aspects of the virus and behavior.

The types of genes that will help protect against Coronavirus

ACE RECEPTORS - this virus becomes infected by binding ACE2 to the surface of the cell. However, the presence of ACE1 is known to reduce the expression of ACE2. The result is a few ACE2 receptors and thus reduces the chance of infection. Data shows that in countries where people have low levels of ACE1, especially in Europe, there is an increased morbidity and mortality. Recent studies have also found that males have more ACE2 receptors and are more prone to infection.

HUMAN LEUKOCYTE ANTIGENS - The genes responsible for the antigen leukocyte antigen, which are the proteins that block the human immune system (immunity), have come in two separate studies suggesting that these differences are easily found in coronavirus and others. Researchers say the identification of a leukocyte antigen variant can help predict the risk of infection and determine who will benefit most from vaccination.

A French investigator examines the role of smoking

Hypothesis - A famous French neurologist has said that the nicotine found in cigarettes is likely to keep the disease attached to the receptors of cells also targeted to the coronavirus. The virus cannot enter the cell and cannot spread through the body if nicotine blocks it. And nicotine can reduce the body's immune system (immunity), known as the cytokine storm that is seen in severe covid-19 conditions.

Numbers - The first finding is based on a study of nearby covid-19 patients. Only 5% of them smoke. Analyzing the data, the doctors concluded that there were 80% fewer smokers among covid-19 patients than the average French population of the same age and sex. In fact a census from a Paris hospital shows that 11,000 patients were admitted with covid-19, 8.5% by smokers in case of electronic cigarettes with 25% of the population in France.

Concern - The idea itself that nicotine may play a role in the prevention of this virus should be tested at a hospital in Paris and reported at the end of last month. At that time a French health official warned that smoking kills 75000 people in France a year. Doctors also point out whether or not the weather is clear, nicotine is a shield and is a virus. Smokers who catch the disease have more serious symptoms due to the toxic effect of cigarette smoke on the lungs.
