Can A Person Get COVID-19 Twice? Here’s What We Know

The World Health Organization says we don’t have evidence to understand why people may experience reactivation after recovery.

Countries worldwide have been fighting against the novel coronavirus using preventive measures such as social distancing and lockdowns. However, after India was in lockdown for almost half a year, it gradually implemented certain relaxations to resume economic activities.

For all the growing research on the novel coronavirus, one question that may concern people is whether they can get COVID-19 twice.

This article looks at the study to determine whether a person can get COVID-19 more than once.

I have already shared a post related to this topic Vaccines Covid 19: Is It Safe To Take? I hope you read this post.

Healthcare professional believes that people who recover from COVID-19 should develop almost robust immunity for at least a few months.

Public health authorities and Researchers still do not know how the human immune system responds to COVID-19 and whether or not people develop long-term immunity after recovering from COVID-19.

It is hard to say these individuals tested positive as a result of a second infection. While the possibility exists, detectable levels of the virus remain in the human body even after symptoms resolve.

The natural immune system fights off foreign pathogens, such as bacteria and viruses. Specific immune cells, called B-lymphocytes or B-cells, identify proteins called antigens on the surface of invading cells.

When a B cell detects an antigen, it causes the production of proteins, called antibodies, that bind to antigens.

When B cells produce an antibody, they can continue making the antibody if the same antigen appears in the future. It is called adaptive immunity.

Immunity offers protection that extends beyond the personal level. For example, when individuals have developed an adequate antibody response, benefits such as “herd immunity” become possible.

Herd immunity occurs when a percentage of a population develops immunity to an infectious disease.

What are the symptoms of reinfection?

The patient from Hong Kong experienced a sore throat, cough, fever, and headache during his first infection, and he was asymptomatic during his second infection. On the contrary, a 24-year-old man in the US developed breathing problems and pneumonia after getting re-infected with COVID-19, despite having mild symptoms during his infection.

What the research says

Herd immunity is not a safe option at the moment. But, researchers are trying to understand how the immune system reacts to COVID.

The participants developed antibodies within 15 days after the onset of symptoms. However, 10 participants had antibodies levels. The researchers reported that elderly and middle-aged patients develop higher concentrations of antibodies than younger individuals.

What should you do once you have recovered from Covid-19?

Recovery after COVID-19 does not mean that you are immune to the disease. You should avoid maintaining hand hygiene, wearing masks, and ensuring social distancing after COVID-19 recovery.

COVID-19 is an almost new disease, and there is insufficient data to understand the kind of long-term immunity that patients develop after recovering from the infection.

Researchers do not know how the immune system reacts to coronavirus or whether people who recover from COVID-19 develop long-term immunity.

The experts suggest that people take preventative measures, such as physical distancing and self-quarantining, if necessary.

Is it right to take care of your health first? Yes! It is.
