According to foreign media reports, US President Biden may be infected with a sub-branch of the BA.5 variant. The specific one has not been clearly announced. Although the vital signs are stable, there is no breathing. Difficult symptoms, but the symptoms of body aches, sore throat, and cough are still relatively obvious. These are the initial symptoms of the new crown. The specific severity depends on subsequent changes. Advanced age is a risk factor, and the age between 80 and 90 is the age with the highest mortality rate. part.
I wrote an article before and mentioned that BA.5 is more infectious and pathogenicity has not weakened. In fact, many people say that the new coronavirus will mutate and become less and less pathogenic. At the time, it overlooked one point, that is, more and more people around the world have been infected with the new crown and vaccinated against the new crown, which itself will reduce the fatality rate of the new crown virus. However, virus mutations sometimes suddenly appear strains with enhanced virulence. This is most evident in influenza viruses. Influenza viruses can be said to have coexisted with humans, but highly pathogenic influenza variants are often prevalent, resulting in death. The rate is also not to be underestimated.
The virus has mutated to BA.5, and the trend of decreasing the fatality rate is not obvious. The specific statistics have not been found yet, but the number of hospitalizations due to infection with the new crown has surged recently in Europe and the United States. The number of patients is also increasing. Although there is a factor of a substantial increase in the number of infections, the possibility of a slight increase in the virulence of BA.5 cannot be ruled out. Biden, as president, will definitely receive far better therapeutic drugs and medical care than ordinary people, but in the end The trend of the disease is still determined by its own physical condition, and the results are difficult to predict.
