Coronavirus reinfection: Scientists say there is no need to panic right now

Doctor warns against herd immunity by infection

Doctor warns against herd immunity by infection

Forty-eight days after testing positive for SARS-CoV-2 in April 2020 and after testing negative consecutively twice, a Washoe County, Nevada patient tested positive again, in June. Some countries are considering it as a strategy to combat COVID-19.

Researchers say the first known case of United States coronavirus is a 25-year-old man from Reno, Nevada, who first tested positive in April after developing a mild illness and then later fell ill in May.

Just a few weeks later, on May 31, the man reported symptoms including all the symptoms he had before as well as a fever and feeling dizzy. It will collaborate closely with ISARIC-4C, an internationally-leading project already underway to examine the immune profile of hospitalised patients with COVID-19, and is supported by the British Society for Immunology.

Because the genetic make-up of the strains are different enough, this represents a true reinfection.

To solidify confidence in the case, Pandori and the research team partnered with the Washoe County Sheriff's Office Biology Unit to conduct identity testing on the specimens and lab samples evaluated in the study to verify the specimens were from the same person.

"Since we do not yet know how frequent reinfections are, it is hard to say what these findings mean for the success of a vaccination campaign", Ranst, a clinical biologist at the academic hospital UZ Leuven in Belgium, told PTI, addressing worries that reinfection might also impact the vaccination programme. "Before we have broader studies illuminating these questions, we can't conclude what a single case of reinfection means for longevity and robustness of COVID-19 immunity and relevance for a future vaccine".

Mark Pandori, director of the Nevada State Public Health Laboratory, said that this finding does not reinfection is likely to occur again. It may also have implications for herd immunity'. He said that even scientists do not know anything regarding the interactions of immunity along with reinfection in such patients, at a time when there are only three such cases in the world.

She acknowledged that reinfection could have happened a few times with COVID-19, but the Monday report out of Hong Kong marked the first documented case.

Kids, young people have less severe Covid-19 than adults
However, the findings also show that children of Black ethnicity were disproportionately severely affected by covid-19 infection. Three children had asthma and three had epilepsy, but no other comorbid conditions or immunodeficiencies were reported .

Following the report from Hong Kong - the case was reported in the media on Monday but the research paper was published on Wednesday - two similar reports emerged, one each from Belgium and the Netherlands.

'If reinfection is possible on such a short timeline, there may be implications for the efficacy of vaccines developed to fight the disease.

Professor Tracy Hussell, Theme Lead for UK-CIC, from The University of Manchester said: "The immune system is one of the most complicated systems in the human body but understanding how it reacts during and after infection with SARS-CoV-2 is critical to our ability to control this pandemic".

"This investment by the NIHR and UKRI will help immunology experts to discover how our immune systems respond to SARS-CoV-2, including our T cell response".

Jha says the case of the Hong Kong patient is 'completely consistent with that'.

Not much evidence exists about the immune response in patients who've been infected with coronavirus.

Can infection with other mild coronaviruses (which cause the common cold) protect you from catching COVID-19 or will it make you more ill?
