Expert warns: “Delta is not the end of the story” | Digital Trends Spanish

While some parts of the planet seem to show a slight improvement in the face of the coronavirus pandemic, others have been complicated by the spread of the Delta variant.

New Zealand, for example, which until recently appeared as an example in the management of the health crisis, has had to reinforce measures in the wake of this dangerous strain.

The appearance of this variant has changed the current scenario of pandemic management worldwide. The problem is that Delta is far from the latest threat from the coronavirus, as experts warn.

In an article published in The Conversation, Hamish McCallum, director of the Center for Health and Food Safety at Griffith University in Australia, stated that “Delta is not the end of the SARS-CoV-2 story.”

The expert in infectious diseases and pathogens also explains what could happen with this variant in the future and with the appearance of other new mutations.

“Evolution is the result of random mutations (or errors) in the viral genome when it replicates. We can expect evolution to favor virus strains that result in a steeper epidemic curve, producing more cases more quickly. “

According to the scientist, this could lead to two predictions. For one thing, the virus is anticipated to become more transmittable. “An infected person is likely to infect more people,” he says.

On the other hand, the time that elapses between someone being infected and transmitting it to others may be reduced. According to the expert, for this reason the Delta variant is thought to be spreading throughout the world, replacing the original Wuhan strain.

“The Wuhan strain had an R-value of 2-3, but the R-value of Delta is about 5-6. Therefore, someone infected with Delta is likely to infect at least twice as many people as the original Wuhan strain, ”McCallum adds.
