The arrival of the new variants of COVID-19 BA.4 and BA.5already predominant in almost the entire world, has caused an increase in infections of coronavirus, although mostly with mild symptoms. These new strains are subvariants of omicronwith a higher level of propagation and more difficult to detect, they have even been called the variants ‘Houdini’.
BA.4 and BA. 5 have also brought with them new symptoms. Likewise, a study by the French Public Health indicated that the symptoms are reduced seven days to four days with respect to the previous lineages of the virus. ‘The Lancet’ has already highlighted in one of the published reports that the symptoms associated with COVID-19 last three days less in people infected with omicron.
Given the increase in infections and the appearance of new symptoms of coronavirus, new vaccines are already underway and are expected to be ready for this fall, coinciding with the vaccination period with the fourth dose of the vaccine. What are the current symptoms of the coronavirus with the new variants that are already dominant?
