What multiple covid infection do to your body ?

 Making the small cuts on the large tree for numerous times leads the tree down. Then won't anything happen to our body if it keeps on getting and recovering from the covid???

Well , absolutely these multiple covid infection must have certain long term or short term consequences on the body. And after the outbreak of the more infectious Omicron variant these reinfection rates are even rising . Let's see what happens to our body when we suffer from multiple covid infections.

A study showed that each new infection added to the body can increase the risk of dying from any causes (not necessarily from the covid). Actually body don't remain normal to the resistance to foreign particles when it encounters multiple covid infection. It get weaken.

It may also provide boost to the fatal disorders of the heart , blood and brain related disorders , as well as it provides the diseases like diabetes, chronic fatigue and long term covid to show their actions with ease (to know more about long COVID read my blog :- https://theomenigma.blogspot.com)

These health risks are mostly associated with the older population than the active or the young group of population and reason for this is not known yet. As the older population are not exposed to the outer world like the other group of the population the. Also the risk of reinfections and the consequences of the reinfections both are higher for this age group? And it is also unclear that how long it takes for out immunity to get resistant to the further more infections. And these all facts make this disease a topic of ENIGMA.

Risks of reinfection differ with disease. For some diseases, including measles, yellow fever, and rubella, there is little need to worry about contracting them again because one case of the illness or immunization confers lifetime immunity. This usually stops you from becoming sick again or causes a very mild infection that you are unlikely to detect. Then there are illnesses for which a person's immunity weakens over time, making them more vulnerable to re-infection. The severity of that reinfection depends on a variety of variables, such as underlying diseases, health changes that may have put stress on the person's immune system, the timing of vaccination, and changes to the virus itself. Consider the flu as an example.

 The immune system is confused by the flu virus's numerous mutations; each fresh infection mimics the first-time flu attack. Therefore, according to Al-Aly, "your body can't respond, 'Oh I've seen you before, I know how to deal with you. Laith J. Abu-Raddad, an infectious disease epidemiologist at Weill Cornell Medicine-Qatar, claims that reinfections are often less severe than initial infections. "The immune system has been prepared, so it makes perfect sense. Although we may have symptoms, the response is so quick that it eventually stops the replication. One exception is dengue sickness. It results in a unique event where antibodies made as a result of a prior infection accidentally aid the virus in invading host cells, working against you. There is no proof that SARS-CoV-2 is responsible for this, and if it were, hospital admissions would probably be through the roof right now. But according to scientists, it's crucial to rule that out as a potential route the virus could travel.

It is now known that COVID-19 immunity, both acquired naturally and by vaccination, does weaken over time. It has been highly contested, nevertheless, how serious those reinfections are. Al-findings, Aly's which was published in June, caused a stir on social media since it appeared to imply that reinfections are more severe than first infections. Al-Aly claims that this was a misunderstanding of his findings, nevertheless. He claims that even if most reinfections are milder, they should still be treated seriously.

Al-Aly argues that the fact that there is some risk involved is important. He compares it to a home fire's aftermath. You cannot tell your spouse, "Let's set the home on fire again, I now know how to put out fire," he advises. "Perhaps your immune system can handle it. Yet, do you know what's superior? Abu-Raddad concurs: "Not to develop an illness in the first place. His own study, which was earlier this month published in the New England Journal of Medicine, demonstrates that those who have had a vaccination and have already contracted an infection are 97 percent less likely to experience a serious, critical, or deadly reinfection. The risk is thus "very, extremely tiny."

But he adds that the cumulative risk of COVID-19 injury rises with each additional infection. Osterholm asserts that additional research along the lines of Al-would Aly's contribute to the understanding of how COVID-19 risks may be increased by reinfections. For instance, he cites the possibility that an infection could result in blood vessel inflammation over time, which could result in the formation of blood clots, which could increase the risk of heart attacks or strokes.He states, "That's an example of something we just really need to get a much better handle on.

Scientists are particularly concerned about whether each new infection increases the likelihood of developing chronic COVID, a mysterious disease that has a lengthy array of inconsistent symptoms and can persist for months or years after an initial infection. Although the etiology of COVID is still unknown, researchers want to know if immunization offers any protection against it.

The evidence is conflicting thus far. According to a September 2021 study published in The Lancet, those who had gotten two doses of the COVID-19 vaccination were half as likely to experience prolonged COVID symptoms as those who had not received the vaccine, indicating that the immunizations may offer some protection. Al-Aly co-authored a study in May 2022 that was published in Nature Medicine and reveals that vaccination only reduces the incidence of long-lasting COVID symptoms by 15%.

Al-most Aly's recent research, however, indicates that those with many illnesses are more likely to have lengthy COVID than those who just had one infection. According to Abu-Raddad, this doesn't always indicate the second infection is worse than the first; it could simply mean that each new infection presents a fresh chance for protracted COVID to manifest itself. However, before considering whether reinfections are a factor, researchers must first understand what causes long-term COVID, according to Benjamin Krishna, a postdoctoral researcher at the University of Cambridge with expertise in virology and immunology.

Some experts hypothesize that viral particles that persist in the body long after the acute phase of the illness has passed are what cause protracted COVID. Others propose that it's brought on by an autoimmune condition that already exists or perhaps by an immune system that didn't adequately recover from a previous disease. Krishna states that he would be astonished if a second infection contributed to the development of protracted COVID. Instead, he believes it to be more like rolling the dice. Every time you roll, there's a possibility you'll develop a chronic tiredness illness, he claims.

Before drawing any judgments regarding the seriousness of COVID-19 reinfections, researchers require further information. The next phase, according to Al-Aly, is to determine whether the dominant variations at the moment—BA.4 and BA.5—are more likely than others to result in severe COVID-19 reinfections. Although the VA database is not flawless, he contends that its substantial scale offers a benefit for sorting through the numerous variables at work: He will be able to examine reinfection in subgroups of patients who only had, example, the Delta variant vs the Omicron variants, thanks to the millions of medical records that are currently on file. Will BA.4 and BA.5 actually evade vaccination? Do they increase the chance of extended COVID in the same way? We all want to know the answers to these unanswered questions, he claims.

Additionally, Abu-Raddad would want to see more research on the clinical characteristics of reinfections. However, this would be a significant undertaking. You would need to undertake a thorough assessment of each individual after each infection to establish whether reinfections produce compound damage to the body. In the end, scientists will require additional time. Krishna notes that even while the pandemic may seem to have been ongoing for two and a half years, that is still a relatively short period of time to examine how antibodies react to a virus. We might discover that reinfections are far worse in another year and a half, or we might reach a point where we are immune for life.

Osterholm points out that a variant or sub-variant could appear and create a completely different equation. He cautions, "Every time we've tried to outsmart this virus, it's made us doubt ourselves." But he remains certain that researchers will be able to better understand it. In the interim, specialists advise people to take a number of prudent precautions, such as masking and avoiding circumstances where there is a high chance of exposure, in addition to getting vaccinated or receiving a booster shot if they are eligible. "We are playing a very dangerous game every time we expose ourselves to reinfection," adds Abu-Raddad. "That particular illness could end up being the one that is particularly dangerous,"
