Early analysis means that should you catch COVID-19 greater than as soon as, you usually tend to face severe well being points.

Virus re-infections are on the rise in Australia following the expansion of two Omicron sub-variants, BA.4 and BA.5, that are anticipated to quickly grow to be essentially the most dominant strains of COVID-19. .

It was hoped that the well being dangers related to the COVID-19 contract would lower with subsequent infections.

However Nancy Baxter from the College of Inhabitants and International Well being on the College of Melbourne mentioned early analysis, based mostly on knowledge collected from the U.S. Division of Veterans Affairs database, confirmed that this didn’t was not the case.

Analysis, which has but to be peer-reviewed, exhibits that whereas there are some advantages to immunity from the virus contract, the prospect of unfavorable well being impacts will increase with every successive an infection.

“You proceed to danger issues like your respiratory issues, shortness of breath, coronary heart issues, long-term covid and … you’ve gotten the next danger of demise than you’d anticipate to have,” he mentioned. Professor Baxter.

“Which implies that the extra you get it, the extra seemingly it’s that sooner or later you should have skilled a extremely unfavorable consequence of getting COVID-19.”

As well as, the advantages to immunity from the virus contract diminish over time, making re-infections more and more seemingly.

“For the primary month and possibly extending to the primary few months after you had Omicron, you’ve gotten some safety in opposition to getting it, however then it declines shortly,” Professor Baxter mentioned.

Whereas the research included greater than 5.5 million folks, solely 10 p.c (566,020) have been girls, leaving potential for inaccurate illustration in a extra balanced inhabitants.

Dr Deepti Gurdarasani from Queen Mary College of London agreed that whereas analysis has some caveats, its findings have important implications for the best way we take into consideration COVID-19 re-infections.

“It’s clear that the narrative of‘ re-infection is benign ’or‘ delicate ’doesn’t actually matter,” she mentioned on Twitter.


Hole in Australian knowledge

In Victoria, greater than 20,000 reinfections have been recorded by knowledge comparability processes.

In New South Wales, that determine is greater than 11,300, nearly half of which occurred after the Omicron variant was launched final November.

However Professor Baxter mentioned these numbers have been a major understatement.

“The figures now we have usually are not massive as a result of the re-infection isn’t being correctly recorded, significantly as a result of it’s not permitting you to register a second COVID-19 an infection should you had it inside 4 months.”

COVID-19 infections under reported

The official variety of COVID-19 infections day by day is about 30,000, which is properly under the height in early 2022 of greater than 100,000.

However Professor Baxter warned that the official figures have been additionally a major understatement.

“We don’t assume they’re being recorded with the identical type of stage of accuracy they might have previously,” she mentioned.

“We all know that PCR exams are more durable to get, … not everyone seems to be recording their fast antigen exams neither is everybody doing COVID-19 testing.”

With the decline in masks put on and neighborhood immunity from the declining January peak, Professor Baxter mentioned she expects infections and deaths to proceed to rise.

“We had a interval of about six weeks the place the numbers have been regularly declining. We are actually seeing a reverse of that pattern the place the numbers are rising once more,” she mentioned.

Professor Baxter reiterated different epidemiologists who known as for a larger deal with masks put on and air filtration to scale back transmission.
