COVID 19: America in the last month or two. Several countries in the Northern Hemisphere, including China and Britain, have seen a wave of cases of viral infections in the respiratory system. Under this, respiratory syncytial virus (RSC), flu and Kovid-19 infections were found in people of all ages.
Apart from this, bacterial infections like Strep-A were also seen in children. Sometimes these infections can also be very serious. The UK has seen a significant increase in the number of patients admitted to hospital during winter, putting further pressure on the health service. This situation has led some to question whether COVID-19 damages our immune systems and increases the risk of other infectious diseases, such as the flu, in people who have already been infected.
Another idea to explain the increase in viral respiratory tract infections is that children ‘escaped’ common childhood infections during the coronavirus pandemic, which made them more vulnerable to these infections due to ‘immune deficiency’. Have made them more sensitive, that means they can easily get sick from these viruses. But how reliable is this explanation?
Covid and immunity system?
Sheena Cruickshank, Professor of Biomedical Sciences at the University of Manchester, said that the immune system develops to deal with different types of infection agents. The immune system has a variety of weapons that work together to not only eliminate infectious agents (viruses, bacteria, etc.), but also to remember these agents for a more rapid and effective response to subsequent infections. keep Similarly, a virus called SARS-CoV-2 infects Kovid-19; it dodges the immune system like other viruses.
Who is more at risk?
SARS-CoV-2, like many other viruses, does not affect all people equally. We have known for some time that certain groups (including the elderly and people with other diseases, including diabetes and obesity) are more likely to become seriously ill if infected with COVID-19.
this weakness corona virus The immune system’s response to K is linked to an abnormal response that results in inflammation. Here we see that there is a decrease in the number of lymphocytes and there is a change in the immune cells known as phagocytes. Despite this, the immune system of these people with a weak immune system becomes normal in two to four months, but some people, especially those suffering from severe Kovid-19 or those who are suffering from other diseases, have some changes six months after infection. Can last till
What is long covid?
Evidence suggests that the most pronounced and persistent differences in immune cells following COVID-19 infection are seen in those who develop chronic COVID. However, till now no data has been found regarding reduced immunity in patients with long covid. While an overactive immune response can actually do harm, the changes seen in the immune cells of patients with chronic COVID seem consistent with a vigorous immune response. This may explain the post-infection complications and symptoms in people with chronic COVID.
What is Immune Debt?
Immune debt is a hypothesis under which it is believed that the development of immunity has collapsed due to lack of exposure to the outside world during ‘lockdown’, especially in children. Under this, it is believed that our immune system forgets the ‘knowledge’ of the past and due to this the person becomes more vulnerable in terms of protection against infection.
