Important information about COVID-19 released
There is an immunity to corona virus? If Yes, how long will this last? And how the prospect of an anti-body test in the near future? These and other questions trying to clarify a current scientific Review.
The researchers at the Imperial College London have discussed in your article, in particular, the immune responses to SARS-CoV-2 and the risk of Re-infection. The results of the public Review were published in the English journal “the Journal of General Virology” (JGV).
Knowledge about SARS-CoV-2 summarized
In the Review of the available scientific knowledge in a number of key areas have been summarized in connection with SARS-CoV-2, and other corona viruses in order to develop strategies for virus control. Of the leading virologists in the UK is the author of the article discussed, in particular, the immune responses to SARS-CoV-2, and other corona viruses.
SARS-CoV-2 as a typical seasonal Coronavirus?
The professors, Paul Kellam, and Wendy Barclay from Imperial College London examined what is so far on the immunity against coronaviruses, including SARS, MERS, and the four strains of seasonal corona virus known. The researchers come to the conclusion that SARS-CoV-2 could be the fifth seasonal Coronavirus, and in the next few years, epidemics of the Virus are repeated may occur.
Beware of predictions
SARS-CoV-2 is a new Virus in humans, and many of the basic properties have yet to be identified. In the absence of such data may only be trying to meet on the basis of the knowledge of the two epidemic corona virus in humans (SARS, MERS) and the four seasonal human corona virus-specific predictions. The return should be taken care of circuits, but they can be a good starting point.
Seasonal corona virus with a similar development?
It is not really known what happens on the way of a new Coronavirus to an endemic seasonal infections, but it could be that four seasonal corona virus, as they are skipped the first Time from animal to human, and showed a similar Transmission and pathogenesis, such as SARS-CoV-2, according to the research team.
Increasing immunity is likely to lead to less disease
In the course of time, when the immunity of the population spread against the seasonal Coronavirus, the number of serious diseases are probably. Nevertheless, the seasonal Coronavirus can cause in some people is still a inflammation of the lungs, reports the researchers.
How long the antibody lasts in the case of corona virus protection?
A number of factors, including, for example, the Severity of the disease, affect how long the antibody persists for protection against both SARS as well as MERS. Studies have shown that the antibody is a decrease in protection with time. In the case of seasonal corona virus, where the disease is mild, there have even been reports of Re-infection after 80 days, explain the researchers.
SARS-CoV-2-immunity needs to be further investigated
It is important, as much as possible about the SARS-CoV-2-immunity to find out. For example, how strong the immune response is and how long it lasts. In addition, it should be identified whether or not people with mild or asymptomatic infections to develop a strong or weak immune response, and what are the measurable properties of immunity, protection from infection predictions.
Understand how to do it with COVID-19 more
Through this Knowledge can better be assessed, such as the SARS-CoV-2 infection with the time to develop. Vaccines, however, are not necessarily comparable with past infections. So it is likely that some of the vaccine would be a candidate in a better position, long-lasting to induce immunity, says the research group.
How reliable is the existing anti-body tests?
In the article, the currently available antibody tests for SARS-CoV-2 to be discussed. The differences between these Tests, their accuracy and their limitations are explained. The Knowledge of the degree of immunity against SARS-CoV-2 in the population could be the key to controlling the spread of the disease and to the understanding of the General risk of infection. The current report will give a current and well-researched Overview of the understanding of the immune responses to these viruses, stress the researchers. (as)
