The appearance of new variants of the coronavirus has led to the symptoms of the disease change throughout the development of the pandemic. This is confirmed by scientists and different studies that have been developed since the arrival of Covid-19 in our lives.

Currently, BA.5 is the variant that appears in most cases around the worldresponsible for the seventh wave and which has increased contagion exponentially.
On the other hand, Centaurus (BA.2.75) It was detected in India and other countries and little by little it spreads to the rest of the world, which has led the WHO to classify it as a “variant of concern” as it produces greater contagiousness.
All of them have had different symptoms that have varied over time: some have become more present with the new variant and others have become lighter with the arrival of Omicron, among other aspects. This has been discussed in the latest report prepared in the United Kingdom by scientists from King’s College London, the country’s health system (NHS) and data from the Zoe Covid application.
