Cases of Covid-19 They are decreasing all over the world, but the virus does not stop mutating, thus causing new variants that have different effects on our body.
In the United Kingdom, an application called ZOE has been tracking the data that citizens enter into their system since the start of the pandemic, which helps to understand how the disease evolves and its consequences. symptoms.
According to the latest report to which the British newspaper The Independent has had access, the most common symptoms of the disease have changed.
Sore throat (57.3%)
Congested nose (57.8%)
Nasal discharge (55.5%)
Sneezing (52%)
Cough without phlegm (50.7%)
Headache (49.6%)
Cough with phlegm (47.3%)
Hoarse voice (41.4%)
Dolor muscular (24,7%)
Smell alteration (22.32%)
More than half of those infected presented sore throat, congestion, runny nose, sneezing, and coughing; while less than 25% manifested muscle pain or smell abnormalities, something that was very frequent at the beginning of the pandemic.
As explained by ZOE, SARS-CoV-2 is constantly evolving and its symptoms have changed for various reasons. The main ones are vaccines and the appearance of new variants.
Greater transmissibility
In Spain, the Ministry of Health ensures that the Ómicron variant is the dominant one. Refering to new subvariant of Omicron (XBB), their lineages stand at 14.1% as indicated by the latest report made public.
From the ministry they remind that the XBB.1.5 lineage evolutionarily comes from XBB.1 which, in turn, comes from XBB, a recombinant lineage of two descendant lineages of BA.2. This lineage has a capacity to evade the action of antibodies similar to that of XBB.1 and XBB, but it has a greater capacity to bind to the ACE2 receptor, which could be related to a higher transmissibility compared to the lineages from which it comes.
