Since the start of the pandemic in early 2020, the Department of Health has recorded 439 re-infections, which are counted if a person is re-infected with the virus 60 days after the first infection. The figures come as a woman from Melbourne revealed this week that she had contracted Covid for the second time in less than four months. Alexandra Duffin, 28, has been hospitalized twice after contracting the more virulent Delta strain in October of last year. Her taste had just started to return a few days before she tested positive for the highly transmissible variant of Omicron in a PCR test this week. “I feel a lot more crowded this time around, but I’m trying to be positive. I managed to get through it the first time around, and even though I was so sick, if I can do it, I can do it again, “Ms. Duffin told The Herald Sun.” I really want more people to know that. Ms. Duffin, who said she ‘felt like Superman’ in the months after her first diagnosis , has since amassed more than two million likes and 70,000 subscribers on the video-sharing app TikTok by telling its rare story.People previously infected with Covid are much less likely to contract the virus for up to six months, but a person is not considered immune or doubly vaccinated after having already contracted it. Deakin University president of epidemiology, Catherine Bennett, said there was nothing to prevent the Victorians from being infected with Covid on several occasions, especially if they have already caught the variant e Delta. “We have both variants in circulation right now in Victoria, so someone could literally get a Delta infection this week and still be susceptible to Omicron in two weeks,” Professor Bennett said. “The immune response to Delta won’t not protecting you from Omicron. Neither previous infection nor vaccination will protect people from infection at this time. “Former World Health Organization epidemiologist Adrian Esterman said the real number of people re-infected in Victoria may never be known. “We have this vast pool of infected people in Australia at the moment that we don’t know anything about, so it is very, very difficult to say who will be re-infected,” he said. he said. Professor Esterman said state and federal authorities should look to other countries such as the UK – where around 15% of daily cases are repeat infections – as an example of reinfection rate to be expected in Victoria in the coming months. recovered from Delta, 80 of them will descend with Omicron, ”he said. “People think, ‘Oh look, I got it. You know, I am protected. Therefore, I do not bother. And that’s exactly what happens when people start to think they can’t be re-infected. that the new exposure was less than 30 days since the first symptom of the case – or test positive if asymptomatic. During this 30-day period, recovered cases may continue to frequent high-risk settings, do not need to be discharged if re- exposed, and will not be required to participate in surveillance testing in part of their employment or studies if they are re-exposed.
