How Many People Have Gotten Covid Twice

I Think Or Know I Had Covid

Can You Get COVID-19 Twice? Infectious Disease Experts Weigh In | NBC10 Philadelphia

You can be around others after:

  • 10 days since symptoms first appeared and
  • 24 hours with no fever without the use of fever-reducing medications and
  • Other symptoms of COVID-19 are improving*

*Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation

Note that these recommendations do not apply to people with severe COVID-19 or with weakened immune systems .

The First Time I Got Covid

The first time I got COVID, hipster that I am, was right when it started trending. It was in March 2020, the first week of lockdown. Back then, we were so young and dumb. There were barely any COVID tests available to the general public . Losing your sense of taste and smell was just a rumored symptom.

Lucien, who uses he/they pronouns, got it for the first time in February 2021. They attribute this to their large apartment building where few people wear masks.

As I lay on my couch and felt like I couldnt move, my partner at the time zipped around me, making jokes and playing music, full of nervous energy. I had a splitting headache that I thought was a migraine. I suggested I may have The Novel Coronavirus, but my partner convinced me it was just anxiety about the world ending. Fair enough. But then I accidentally smashed a bottle of perfume on my bathroom floor and it smelled like nothing.

Lucien also had a high fever and contemplated going to the hospital that first time, but they opted to just eat a bunch of Tylenol and try to sleep it off. Luckily, that worked.

A couple months later, my sense of smell had returned and I tested positive for antibodies. My live-in partner, for whatever reason, did not.

Does Omicron Mean Boosters Are More Important

Early data suggests that boosters should help fight against omicron, because antibodies increase significantly after getting them.

Offit said a lot will depend on upcoming data that will determine whether omicron is more or less virulent, and comparisons of patients who have received only two doses versus two doses and a booster.

My prediction is that what youll find is that there really isnt any difference in protection against serious illness, but that there would be a difference in protection against mild illness, he said. And then the question is: Is that what we want? Do we want to try and protect against mild illness in young, otherwise healthy people?

How Much Natural Immunity Do I Have From Being Sick

Prior infection with COVID-19 reduces your chances of getting sick by about 80% after six months, according to a study published in The Lancet in March. For people over age 65, the protection is 47%. The same study points to research from the UK that found that natural immunity lasts at least six months after infection.

However, the amount of natural immunity someone has varies person to person, Weissenbach noted. “Every individual is different,” he said. “If you’re dealing with someone who has underlying health conditions or is immunocompromised, the concept of natural immunity can be quite a bit weaker.” Factors like how much immunity a person’s body mounted during the first infection, how much of the virus you were exposed to and the time between COVID-19 infections can all play a role.

In the University of Chicago Medicine Q& A, Pisano said that while it’s possible for someone to have a higher antibody response to COVID-19 after getting sick than they would from getting the vaccine, there isn’t enough data to compare how infection severity or antibody responses affect coronavirus immunity.

“We don’t have clear data on how antibody responses from a mild infection compared to a severe infection, or how protective those antibody responses are,” Pisano said.

Can You Get the Coronavirus Twice? Scientists Struggle to ...

By now, we know that anyone can get COVID-19 the vaccinated and unvaccinated, those who have had it already and those who havent. In the same vein, anyone can get COVID-19 again.

Its important to note that were still learning a lot about reinfections and whos at risk for those reinfections, Dr. Esper says. But doctors do know that some people are at higher risk of reinfection for COVID-19 than others.

How To Protect Yourself From Getting Covid

Being infected once is not a hall pass to ignore safety protocols like masking, hand washing and physical distancing. Even if reinfection doesnt cause you to become sick, you could still become a transmitter of the virus and infect others.

The number one way to protect yourself and your family from this virus is to be vaccinated, but its not a silver bullet, Dr. Esper says. We have to keep everything on the table and do everything that we can. That includes wearing masks, social distancing, good ventilation, hand washing and everything else weve been doing for the last year and a half.

Will The Common Cold Give Me Immunity To Coronavirus


The jury is still out on the field of “cross-reactivity” but there may be some infections that look similar enough to the virus that causes Covid that people may gain some protection.

Laboratory tests show the T cells some people made to fight Sars or common cold coronaviruses can also react against the new coronavirus.

How common this is and how much protection it gives is still unknown.

More Than 90% Of Federal Workers Have Had A Shot By The Covid

Fortunately the family’s worst fears did not unfold. Genoveva was out of town when her great-granddaughter, Maricia, brought the virus home this time, and Maricia herself recovered. The other adults did not develop symptoms they credit the COVID vaccinations they’d been able to get before the delta surge this fall. Research published by the Centers of Disease Control and Prevention concludes that vaccines offer better protection against reinfections than a natural infection. However, if a breakthrough infection occurs after someone’s been vaccinated it will act like a natural “booster” and result in hybrid immunity according to Chin-Hong. He suggests most patients who are not immunocompromised wait three months until after a recent infection before getting a vaccine or a booster.

“Each exposure we have, whether it’s from the infection or whether it’s from the vaccine, improves our ability to combat an infection the next time around,” says Dr. Julie Parsonnet, a professor of medicine and infectious diseases at Stanford University.

But Parsonnet also notes there are a lot of variables at play. First, immunity wanes. Second, the virus can mutate. Third, no vaccine provides 100% protection, and the shots may not be equally protective for everyone.

“Our neighborhood has three, four generations living in the same house,” Genoveva says.

Can you get coronavirus twice?

A man receives a COVID-19 test at Los Angeles International Airport on Dec. 22, 2020, in Los Angeles.

Its very rare for someone to get infected with the coronavirus causing the disease COVID-19 a second time, but the few confirmed cases of reinfection tell us that immunity to the virus isnt guaranteed and that vaccination could become a regular part of our medical care going forward.

There are about 60 confirmed cases of reinfection globally. Thats far less than 1% of the 112 million coronavirus cases reported around the world. BNO News, a Dutch news site, is tracking reinfections at a global level its identified 57 confirmed cases of reinfection along with roughly 11,700 suspected or probable reinfections.

Reinfection is thought to occur when protective antibodies wane in people who have previously contracted the virus or in people who contracted the virus without developing antibodies.

I dont think anyone had the expectation that if you had COVID and got over it that you could never get it again.

Dr. Bruce Polsky, NYU Langone

For some infectious-disease doctors, this isnt a surprise.

I think everyone anticipated that there would be reinfections at some distant point after the initial infection, said Dr. Bruce Polsky, an infectious-disease physician at NYU Langone Hospital on Long Island. I dont think anyone had the expectation that if you had COVID and got over it that you could never get it again.

Previous Positives Vaccine Not Enough To Stop Johnston County Man From Getting Covid A 3rd Time

SMITHFIELD, N.C. At one point, many people thought catching COVID-19 would protect you from getting it again. But as the virus continues to mutate, thats not necessarily the case. One Johnston County man said hes been sick with COVID-19 not once, not twice, but three times.

Cody Purish has the routine down. He stays in his room, away from his family, hoping not to infect anyone else with COVID-19.

Its been nearly a year since he first caught the coronavirus last January. He got it for the second time in August 2021. At that time, he was partially vaccinated. Now hes fully vaccinated, so when he came down with a sore throat and runny nose, he didnt really consider COVID-19 at first.

I thought it was cold or sinus infection, maybe the flu, he thought. With COVID-19 so prevalent in the community, he got a test just in case.

He said it came back positive.

Youd think being fully vaccinated youd be somewhat immune from this by now after having it two times, but I guess not, Purish said.

We know that all immunity wanes, explained Jessica Dixon, an infection prevention specialist at WakeMed. You cannot expect a history of infection to protect you for very long. We generally say you are not going to get reinfected within 90 days. Beyond that, its like all bets are off and theres so much with this that is changing as these variants emerge.

Are You Only At Risk Of Reinfection Due To New Variants Of Covid

New variants are a big concern for reinfection. Scientists are finding new variants that your immune system might not recognize. Worse, many of the new variants are more infectious than the initial COVID-19 virus. So there are definitely reasons to be concerned about new variants.

The question of whether you can be reinfected by the same strain of COVID-19, and how likely it is, is up in the air. COVID-19 is a coronavirus, and other types of coronaviruses that infect humans exist, usually causing mild cold-like illnesses. These other types of coronaviruses circulate throughout the population. Once you get infected, you are only immune for a year or two. After that, you can be reinfected.

Its not clear if the COVID-19 virus will be the same it will take time for us to know for sure. Its possible that we will see more cases of reinfection as time passes, because the protective immune response people get after the first infection with COVID-19 might disappear.

You May Be Able To Shorten Your Quarantine

Your local public health authorities make the final decisions about how long quarantine should last, based on local conditions and needs. Follow the recommendations of your local public health department if you need to quarantine. Options they will consider include stopping quarantine

  • After day 10 without testing
  • After day 7 after receiving a negative test result


In areas using options to reduce quarantine times, people who are asymptomatic can use a negative test result collected on day five after exposure to exit quarantine on day seven , with additional self-monitoring. The day of exposure is considered day zero .

The First Big Study On Covid

Can you get the COVID

The possibility of coronavirus reinfection has been a concernsince the first reports of people getting sick again began popping up in 2020 while many around the globe were still in isolation. But there has been relatively little data up until this point on how widespread a phenomenon this is.

The first large-scale investigation to tackle that question was published in The Lancet this week, and it found that the vast majority of people who have had COVID-19 are indeed protected from catching it again for at least six months. However, people ages 65 and older are far more likely than younger individuals to experience repeat infection.

The researchers analyzed data from Denmarks national COVID-19 testing program, which has offered free PCR testing to roughly 4 million people living in the country. Overall, they found that a very small percentage of the population 0.65% experienced reinfection.

For those 65 and under, getting the coronavirus once provided roughly 80% protection against reinfection. But for people 65 and older, it provided only about 47% protection against getting COVID-19 again, further highlighting how dangerous this disease can be for older adults.

Given what is at stake, the results emphasize how important it is that people adhere to measures implemented to keep themselves and others safe.

Immunocompromised People Are At Risk Of Reinfection Too

People with immune problems are at a higher risk for COVID-19 reinfection than the general public, which is why the U.S. Food and Drug Administration has authorized booster shots of Pfizer-BioNTechs and Modernas COVID-19 vaccines for immunocompromised individuals.

We always knew that people with immune problems were more likely to have less of a response to the vaccine and more likely to get a second infection after they got the vaccine, Dr. Esper says. Booster shots are designed to help reduce that likelihood.

Cdc Backs Expansion Of Covid Boosters For All Adults

Computer models in a recent study suggest that people who have been infected by the virus can expect a reinfection within a year or two if they do not wear a mask or receive a vaccination. The findings show that the risk of a second bout rises over time. A person has a 5% chance of catching the virus four months after an initial infection, but a 50% chance 17 months later.

“The second time it was scarier because I’m vaccinated,” says Vanessa referring to the family’s second bout with the virus in October 2021. “Her dad’s vaccinated. We’re protected in that sense, but she’s not.”

Her 8-year-old daughter was still too young to qualify for a vaccine. This fall the little girl lay in bed wheezing. Vanessa tripled down on Maricia’s asthma medication and the parents quarantined themselves inside, too. Vanessa shuddered at the prospect of telling her mother and grandma about a second round of positive test results.

Why Do Some People Test Positive Again

There are reports from different countries of people hospitalised with COVID-19 who tested negative when they were discharged, before testing positive again.

However, a study from China found those who retested positive didnt get any sicker. This suggests these people were intermittently shedding the virus and were at the tail end of their original illness, rather than getting a new COVID-19 infection.

The nasal and throat swab test being used to detect the virus also cant say whether the virus is alive or not therefore, they could have just been shedding dead virus. This could explain why their close contacts didnt become sick or test positive.

Is Getting Reinfected With Covid

TRUST INDEX: Can you get COVID-19 twice?

As of August, Weissenbach said COVID-19 reinfection cases make up less than 1% of all COVID-19 cases. But tracking reinfection accurately is difficult because of decentralized testing, lack of communication between labs and a limited number of US labs that save COVID-19 testing samples, he said. In order to confirm reinfection, scientists need to compare the genetic material of previous and current tests.

Another factor that might lead to underreported reinfection cases is that many second instances of COVID-19 are mild, which leads people to not realize they’re infected again, virologist Theodora Hatziioannou told Healthline.

Recovering from COVID-19 can require bedrest.

Is Reinfection More Likely With The Delta Variant

The delta variant is much more transmissible than past variants and experts think it might be causing more severe disease. According to a CDC presentation, reinfection rates with the delta variant might be higher than reinfection with the previously dominant alpha variant.

Weissenbach said that reinfection with viruses, including the coronavirus, is expected at some level. “Much like the flu virus mutates every year, we’re seeing different mutations among the circulating variants of COVID-19,” he said. So far, no variant has found a way around our vaccines, as they all continue to protect against severe disease and death caused by the coronavirus.

But the ever-evolving virus will continue to mutate and form new variants so long as a significant portion of the population remains unvaccinated or without immunity. As it does, experts fear there could be a variant that strips away protection from the initial vaccines.

Bottom line: “It’s worth re-emphasizing that the vaccines are safe and effective at providing a protective immune response against the virus,” Weissenbach said. “Inherently that benefit would minimize any risk of either initial infection or potential reinfection.”

You May Still Be Able To Spread It

Remember, just because you feel fine doesnt mean youre in the clear and reinfection may not present the same as your first bout of COVID-19.

Your previous infection may prevent you from getting sick, but that doesnt necessarily mean that you cant become infected and spread it to others, Dr. Esper says. You might think youre safe because your antibodies are there, but if youre still able to spread it to others for a short period of time, youre still a risk to others.
