THERE ARE SEVERAL CASE REPORT OF REINFECTION FROM SOUTH KOREA AND OTHER COUNTRIES

What so ever the chance.. IMPROVE YOUR IMMUNITY, BUT DONT TRUST IT.

The chances of COVID-19 reinfection are always there because the acquired protective immunity against SARS-CoV-2 is short lived.

The following study indicates that a previous history of SARS-CoV-2 infection is associated with an 84% lower risk of infection, with median protective effect observed 7 months following primary infection.

Nice question

Experience has shown that there is every likelihood that there will be re-infection of covid-19 as observed in most cases of similar infections. Experience, they say is the best teacher.

@Narimen looks like there is still neither consensus nor clinical evidence in this matter right now.

Please check the recent paper also

Sure, interesting opinions comming up

I personally know 4 people who were infected with the virus. All individuals had bilateral pneumonia. After 7-8 months, they became ill again and tested positive for COVID-19.

I think that the lungs cannot recover in such a short period of time and that it is quite fatal.

All people have major problems with fatigue that does not go away.

reinfection is documented already, even though uncommon.

I have few cases of reinfections even after 2 doses of vaccine

So reinfection is a sure thing! That effectively means covid is going to strike again in massive numbers when the people who have developed some resistance run out of immunity phase.

THERE ARE SO MANY REASONS

Shayaq Ul Abeer Rasool

1. Quite a few re-infection cases have been scientifically documented

2. Animals can get COVID-19 from humans. Can animals be re-infected with the virus.

It was found that antibodies due to natural infection persist for about 3 months in 12% and for about 6 months in 88% of infected individuals. So that reinfection may occur after about 6 months of the first infection.

The chances of reinfection, i.e. re-infection with the SARS-CoV-2 coronavirus after an early recovery from a new infection and possibly from Covid-19 disease, are correlated with the periodic emergence of new, more infectious varieties of this virus. The new, mutated variants of Coronavirus that arise every few months are so different that the antibodies produced in the human body (naturally after infection or by administering a Coronavirus vaccine) no longer recognize this new variant of Coronavirus and then reinfection and possibly also a specific phase / scale of usually more or less mild, asymptomatic or weakly symptomatic development of Covid-19 disease.

@Dariusz true there are many cases of reinfections now possibly by new mutants.

The chances of SARS-CoV-2 reinfection is common within 3-6 months from the first infection.

Emerging of new variants or strains of SARS-CoV-2 will increase the chances of reinfection.

What decides if the covid reinfection will be more severe or not? Is their some biomarker or a diagnostic test to detect that

Confirmed cases of SARS-CoV-2 reinfection after recovery from COVID-19

Have a look at the evidence in my answer in this link:

https://www.researchgate.net/post/Are_there_really_cases_of_re-infection_with_the_coronavirus

COVID-19 vaccinated people are more protected from SARS-coV-2 infection compared with reinfection in those who have had recovery from COVID-19 illness

In a study on Qatar airline passengers getting re-infection in non-infected versus SARS-CoV-2 reinfection in those who have had previous COVID-19 infection versus those who had been vaccinated, it was found that the vaccinated people were less likely to be infected versus people who got reinfection after recovery from COVID-19.

Also, take a look at this link.

There are great individual variations.

The increasing number of variants of COVID-19 increases the risk of reinfection.

The possibility of reinfection after recovery is not unexpected because of uncertainty about long term immunity following SARS-CoV-2 infection.

I think the chance is 50 to 50. You can get infected. Depends on many factors that cannot always be foreseen. And there are too many new stamps. And vaccines are not "imprisoned" for everything.

I got reinfected with COVID-19 even though I was vaccinated but the symptoms were not that severe. I got the delta variant second time around. And now I have taken the booster shot too. So lets see if there is a third time too ?

Taken together, studies point to a 1% risk for reinfection after an episode of COVID-19. Although, the mechanisms underlying certain factors associated with reinfection need further investigation. https://www.jwatch.org/na54095/2021/09/30/elucidating-reinfection-after-covid-19

That depends on how your environment is.

Very insightful answers indeed! Is new covid wave any different from earlier ones?

A difficult question, as too many parameters should be taken into consideration. The highest risk is between the first and second immunization, when antibodies (if any) are immature. Then, all depends on the amount of neutralizing antibodies. Depending on immune status of the patient, the vaccine, and antibody titer, reinfection might occur in ~1-3% of immunized persons. Keeping in mind a high genetic plastisity of the virus, these numbers can grow significantly, as a consequence of appearence of new virus mutations.

Omicron variant (B.1.1.529) is linked to much higher rate of SARS-CoV-2 reinfection in South Africa.

It seems new variants change the game altogether. More mutations at critical spots can increase reinfection and make vaccination redundant.

حسب الحالات التي ظهرت في الواقع ان الإصابة بالفيروس متوقعة حتى بعد أخذ اللقاح والسبب ربما يكمن في عدم فعالية اللقاح الكاملة في توفير المناعة الكافية فضلا عن أن الفايروس يحتوى الى أشكال جديدة لم تكن في الحسبان عند إنتاج اللقاح

SARS-CoV-2 reinfection is uncommon and mild, particularly in vaccinated people.

Basically it will be affected by several factors such as the matching antibodies from vaccine, the immunological status of individuals, the presence of co-infection with other pathogens and RBS variability of the new variants in compare to the vaccine based on.

SignificantLu high

People who have been infected with SARS-CoV-2 can expect to become reinfected within one or two years, unless they take precautions such as getting vaccinated and wearing masks.
