Can a person get corona infected more than once?


It’s been almost more than one year where the whole world is fighting against the novel coronavirus with various preventive steps, including wearing a double-layered mask, social distancing, and lockdown. Especially, the second wave of the corona has made us struggle for everything to prevent the spread of the virus.

As per the people who believe in mathematical models, India may see exponential growth in cases far beyond what it saw in the first wave. The battle against COVID-19 could be made much easier if those infected develop sufficient immunity via antibody production. In cases of reinfection are confirmed, the fight to control the disease will be much more difficult. This fight starts with online doctor consultation for covid positive given at home containing the spread of coronavirus.

How our immune system fights against the Coronavirus –

The human body’s reaction to infection is divided into two stages. An innate immune response first, in which chemicals and white blood cells are released to combat and kill a virus. The second is an adaptive immune response, which generates targeted antibodies that can bind to a virus and stop it, among other things. If the latter is powerful enough, it can produce a long-lasting response to the infection, providing the subject with long-term defense.

Those that have the most severe infections have the most powerful immune responses. Since most people who contract COVID-19 have mild to no symptoms, they may have a weak immune response the next time the virus enters their system, according to studies.

Even if immunity is established, it is uncertain how long it would last since COVID-19 has not been around long enough, even though other viruses, the common cold, have a short-lived immunity. Antibodies to more serious coronaviruses, such as SARS or MERS, have been found in people years after being infected.

Understand the reinfection of covid 19 –

Reinfection means that a person has been infected once, cleared the infection, and then been infected again. According to preliminary data, the COVID Immunoglobulin G (IgG) antibody is usually tested positive after 2-3 weeks of infection in the case of disease. However, in some instances, the antibody tests negative, indicating that the individual did not gain immunity due to the condition.

Another explanation is that the antibodies are short-lived and rapidly vanish, leaving the patient vulnerable to reinfection. As a result, reinfection cases indicate that antibodies are not formed in every patient, or if they are, they may not survive long enough, allowing the virus to re-enter the body and cause disease. Also, as per the World Health Organisation (WHO), there is currently no proof that patients who have recovered from coronavirus disease have antibodies and wouldn’t get infected from a second infection.

Importance of immunity of being getting infected twice – 

A Patient can be symptomatic or asymptomatic during the second infection. Immunity protects you from infection and reduces the virus’s effect on your body. To make the lockdown effective and result-oriented, it’s essential to know who is at risk of contracting and spreading the infection. The virus’s ability to be contained would be determined by the duration of immunity gained from infection or vaccination. If the vaccine is effective for life or needs annual doses, it will depend on how long the antibodies and immunity against the virus last. But, in case someone gets infected again, online doctor consultation for covid positive patients will help ensure the best quality consultation at home.
