A new version of COVID-19 is one of the most infectious diseases the world has ever seen, an expert says and says almost everyone is going to catch it. Professor Adrian Esterman, an epidemiologist and biostatistician, says that the variant is six times more transmissible than the original strain of Covid.
Prof Esterman, a former World Health Organization scientist, was speaking in England as cases of Covid rose by 48% in a week, doubling in China the worst level the country has reported since the start of the pandemic and tripling Australia’s share. seen from According to the report of The Mail, this jump is believed to be inspired by the new variant BA.2.
James Wood, a public health mathematician at the University of NSW, said: “We think [the first] Omicron is very similar to Delta and Ba.2 is then another 25-30 percent more contagious.”

According to the Mail, even people who have been triple vaccinated are at risk of contracting the new strain. They say that BA.2’s R number – the rate at which it can spread – is 12, compared to 2.5 for the original virus. Professor Esterman said this level of infectivity makes the new strain ‘very close to measles, the most infectious disease we know of’.
Prof Esterman says that BA.2 causes less severe disease than previous strains. But he said that all types of Kovid are dangerous.
He said: “The problem is that it causes more severe illness in vulnerable people than influenza, and it has the potential to cause real harm to young people as well. Many young, healthy and fit people die from COVID.” There have been cases. I can’t remember that ever happening with influenza.”
He added: “Covid-19 can attack every part of the body, from clots to the heart and brain. There have been cases of a multi-system inflammatory condition, even in young children.”
Prof Estermann said: “It is true that epidemics become less contagious over time, but this happens in 100 years, not in one year.”
