Probably one of the most dreaded questions that a lot of people have asked is, ‘Can I get coronavirus twice’? But, the most awaited answer shows that the results can surely be positive twice, even after the hospital has dispatched you with a congratulations sign in a note.
As coronavirus spreads across the globe, there surfaced a question of the possible immunity of the said patient? This question is important for understanding who can safely go back to work, in addition to understanding just how long the worst consequences of this pandemic are most likely to continue. The answer isn’t fully understood since the virus is new. But so far, scientists say it appears like SARS-CoV-2 likely causes resistance as with other coronaviruses. That means that the body will likely retain a memory of this virus to get at least a few years and ought to be protected from reinfection, at least in the short term.
As India is slowly topping the charts, the government has decided to implement a full-blown lockdown, and now everything is opening up in phases. The lockdown has affected millions of sectors from all around the world, especially in India where it was implemented before handily and without any discretion. Experts have said that implementing another lockdown in India is now not possible since people are recovering and slowly getting back on their feet. If another lockdown is implemented in the whole nation then everyone will fall back to their feet.
So, what do the reports say?
This raises concerns regarding our capacity to build immunity at the least natural means, in addition to heightening concerns.
“The results call for caution concerning antibody-based ‘immunity passports,’ herd immunity, and possibly vaccine durability,” a recent correspondence in the New England Journal of Medicine said, even though the column noted additional study is required. But antibodies aren’t the be-all and end-all of immunity, experts say. And it is still early days at the study of SARS-CoV-2.
“The sickest people tend to have greater antibodies circulating in the bloodstream compared to people with no or mild signs,” explained Chris DiPasquale, director of assay growth at Babson Diagnostics, a Texas company doing COVID-19 serology (antibody) tests.
Can the vaccine trials be affected by it?
Yes, experts have commented on this situation and have said that the vaccine trails which are ready to launch can be hard to produce if the protein spike of the coronavirus changes rapidly inside the host cell.
“We don’t know when this coronavirus pandemic will come to an end. According to our estimate, we are seeing a rising number of cases every day and a growing concern of health over the general public. With the change in the strain of the virus and how one person is getting infected twice, we might have to check out various samples and trials of a vaccine before we come to a conclusion”, Kumar Sahu from Apollo University has commented on the situation.
It becomes hard to know which antibody has developed
A person’s immune system involves an intricate array of production cell actions, and also responses that are associated to conquer a disease. When someone experiences a virus, then B cells, helped by “helper” T cells, then create neutralizing antibodies that attack and destroy future instances of the virus before someone becomes sick.
The antibody tests are rapidly failing every day and this can be a growing concern over individuals who are printing vials of vaccine to contain the spread of the virus.
That cell has two tasks to do before it expires when its first cell is attacked by a virus in the body, said a professor of Medicine, Benjamin Tenoever. The cell that is infected needs to issue a call for reinforcements, sending a cascade of chemical signals which will activate an army of immune cells to come battle with the virus out.” Plus it must issue a warning to other cells to strengthen themselves known as interferons.
They trigger manner to be entered by those cells, once interferons land on neighboring cells. The cells block the transport of proteins and other molecules across their interiors slow down their metabolism, also slow down the procedure by which instructions act as other molecules and proteins, transcription.
There is a low level of virus
It’s not unusual for germs to persist at elevated levels within the body after somebody recovers from an illness,” said a virologist at Michigan Tech University, Ebenezer Tumban.
As an instance, the Zika virus and Ebola virus have been known to stay around for weeks after patients recuperate, Johnson noted. The Tamiflu they took might have pushed on the number of copies within their bodies down to only a few, ” he explained.
The viruses might have started copying at a minimal level following the treatment finished, Tumban explained. There wouldn’t have been a lot of this virus hence no indicators were believed by the patients. However, the number of copies could have gotten enough to the exam to grab them.
