In 60 days, a single infected person can infect 14m people
The mainland edition of the Diário de Notícias reports that the new variant of SARS-CoV-2, Omicron, detected just over a month ago in South Africa is already considered to have the fastest propagation in history.
According to US specialists, this virus ‘conquered’ the planet in just one month. It’s stronger than the Measles virus. One person infected with Measles causes 15 infections in 12 days, one infected with Omicron 216. In 60 days, it is estimated that a single person infected with this variant can infect 14 million people.
Dr. Roby Bhattacharyya, a specialist in infectious diseases at Massachusetts General Hospital, USA, has no doubts: Omicron is the known virus that has the fastest spread in all of history. Within a month, after its identification in a region of South Africa, this new variant of SARS-CoV-2, which came to dethrone the Delta variant, is already dominant in countries all over the world and with more cases than ever. “It’s an incredibly fast spread,” says Roby Bhattacharyya in today’s issue of Spanish newspaper El País.
To support his thesis, the researcher compares the path taken by Ómicron with that of other viruses equally strong in terms of dissemination, such as measles. Bhattacharyya even says that this is the most logical opponent, as it is known as one of the most contagious in the entire history of viruses.
He explains: “A person infected with the Measles virus infects another 15, if they are not vaccinated, Ómicron infects six”, he says, but the key to the faster spread of the Ómicron virus in relation to the measles virus has to do with with the contamination time. That is, in the case of measles, the contamination interval is 12 to 15 days from the time the first person is infected until the others are infected, in the case of Omicron this interval is only four to five days, which the doctor considers “explosive”, underlining:
“A case of measles will give rise to 15 more cases in 12 days, at least. A case of Omicron gives rise to another six in four days, which means that in eight days it gives rise to 36 cases and in 12 days to 216”, summarizes Bhattacharyya.
There were another 1043 cases recorded in Madeira yesterday – details on the link below as usual.
