“#What we know about COVID-19 reinfection from other diseases<\/strong>”<\/p>\n

\n Cases of COVID-19 patients being reinfected have cropped up around the world but experts say it\u2019s unclear whether the virus will be like the vast majority of diseases and not return more severe on its second go-round.<\/p>\n

\u201cSo far these cases app<\/a>ear to be very rare but they\u2019re also not very surprising,\u201d said David Hirschwerk, an infectious disease expert at Hofstra University\u2019s Zucker School of Medicine.<\/p>\n

Hirschwerk said that health experts know from other seasonal coronaviruses that people can become reinfected despite having developed a degree of immunity the first time.<\/p>\n

\u201c[Immunity] certainly doesn\u2019t last for someone\u2019s entire lifespan,\u201d Hirschwerk told The Post.<\/p>\n

So far, there have only been a handful of cases of reinfection documented out of the more than 37 million people across the world who have contracted the virus.<\/p>\n

\u201cI\u2019ve been puzzled that we haven\u2019t heard about more of them, but to prove it\u2019s a true reinfection is kind of a high bar,\u201d said Dr. Nicole Iovine, an infectious disease expert at the UF Health.<\/p>\n

There may have been people who experienced symptoms again months later, but they didn\u2019t seek treatment or their doctors don\u2019t have clinical specimens to prove it was a second infection, Iovine said.<\/p>\n

\u201cYou need the isolates from the patient so you can sequence or fingerprint them to see that they are a truly different strain,\u201d she said.<\/p>\n

So as a result, it still remains unknown whether reinfection cases will be far and few in between.<\/p>\n

Dr. William Schaffner, a professor of infectious disease at the Vanderbilt University Medical Center, said there are some viruses where cases of reinfection are so rare that they often appears in medical journals.<\/p>\n

\u201cWe know that reinfections sometimes occur with some viruses, they\u2019re general<\/a>ly pretty rare,\u201d Schaffner said.<\/p>\n

He said, for example, people can become sick again with measles and chickenpox but \u201cit\u2019s not a common event.\u201d<\/p>\n

\u201cOne of the things that\u2019s true about measles is that the antibodies created are that is the dominant way the body fights off the virus and remain with you for life,\u201d he said.<\/p>\n

Both measles and chickenpox do not mutate quickly, therefore immunity is often lifelong in most cases.<\/p>\n

Experts said COVID-19 has been fairly stable genetically but it\u2019s still too soon to say where on the spectrum it falls between measles and influenza, which could have four strains circulating at any given time.<\/p>\n

\u201c[Flu] is such an ingenious virus that you don\u2019t really have lasting immunity year to year because it\u2019s able to mutate so significantly,\u201d said Sandra Kesh, infectious disease specialist at WestMed Medical Group.<\/p>\n

Experts could only cite one example of a disease that has a worse clinical outcome during reinfection \u2014 dengue fever, which if caught again kicks in an adverse immune response that can be fatal.<\/p>\n

Most diseases either don\u2019t return, or have similar or more mild symptoms.<\/p>\n

But there have been two documented COVID-19 reinfections where the patients have seen worse outcomes the second time.<\/p>\n

A 25-year-old Nevada man\u2019s second case was \u201csymptomatically more severe,\u201d while an 89-year-old Dutch woman who had a rare form of cancer died when she fought the virus again.<\/p>\n

But experts said there\u2019s not enough evidence that a second bout would be more severe.<\/p>\n

\u201cThe second infection tends to be milder or some cases symptomatic with the exception of the Nevada man and the Dutch patient, who was a unique situation,\u201d Kesh said.<\/p>\n

\u201cWe are talking about a very compromised host, and that\u2019s not a surprising outcome given that she was on chemo, she had cancer and her advanced age.\u201d<\/p>\n

Kesh said more research is needed tracking reinfections, but what she sees so far has been promising.<\/p>\n

\u201cIt is reassuring that second infections are milder or asymptomatic or similar to the first infection,\u201d she said.<\/p>\n

But she added that \u201cthe next couple of years will be a process of learning\u201d<\/p>\n

\u201cWhat we learn about the genetic dexterity of this virus and the immune response that is generated and whether the immune response is enough to come back for a different strain of COVID really remains to be answered,\u201d she said.\n <\/p><\/div>\n
