What Do Antibody Tests For SARS-CoV-2 Tell Us About Immunity?
It has been months, that we are facing the COVID-19 pandemic, and still the Government or the public health officials don't know the exact figures of how many people have come in direct contact with the culprit, SARS-CoV-2. There are in fact several nations where the testing facilities have lagged way behind the spread of the virus. Several research organizations, companies and even the Federal and State Government are racing with one another in search of antibody tests to shine a light on the exact spread of the contagious disease.
While the tests based on polymerase chain reaction, detects a virus's genetical materials, an antibody test can surely give an upper hand by screening the virus attacking antibodies, which are formed mainly just after the initial infection. These antibodies generally have a tendency to stay in the blood of the victim long after the virus is removed. The US FDA gave authorization to such a serological test in the early dates of this month. There are, in fact, a lot of other groups that are making such type of tests and even trying to deploy them.
How These Antibodies Response To The Novel Coronavirus?
There is enough evidence of the COVID-19 patients developing such antibodies in their bodies resisting against the virus, something similar to what a human body does for all infectious pathogens. A recent study made by a group of clinical chemists in the University Of California, states that patients infected by this novel form of coronavirus develop antibodies within about two to fifteen days of showing symptoms. Though this data has been skewed in many severe cases and most of the subjects that are tested have been critically ill and even hospitalized. It isn't clear yet if asymptomatic cases will be developing similar symptoms in future.
In the case of most other viral infections, the amplitude of the antibody response correlates very well with the size of the infection. In simple words, a severe case of disease or infections is way more memorable to the human immune system. Researchers even noticed that the preprint of the coronavirus patients in Wuhan, China has also reported the same positive correlation between the patient's age and the antibody levels, which is a direct relation with the severity of coronavirus symptoms. If it was the case that a mild COVID-19 infection is less capable of producing a detectable antibody response, it could even reduce the helpfulness of the antibody tests in order to detect mild cases.
While each and every country is facing the pandemic with courage, doctors, nurses and the medical team still remains to be in the first line of defence. Current reports state that there is a massive shortage of trained nurses and medical staff in the US.
In order to fulfil the deficit, the Centers for Disease Control and Prevention, and some other American government organizations came up with some brilliant ideas and plans. Their plan includes several instructions for the nursing schools and Institutes of Higher Education of America to fight against this dreaded disease. Erudite online nursing schools, being an elite institution, has come up with many online accelerated nursing programs to help the existing nurses in their fight against the COVID-19 disease.
