Omicron 5, those taking Covid a second time with BA.5 ‘could have more serious complications’: US study

Worldwide, the latest sub-variant of OmicronBA.5, soon becomes the dominant strain virus SARS-CoV-2. The “New Covid”a Just No. 1 in the US: In the last week of June, BA.5 accounted for more than half of all new cases of Covid-19, according to new estimates from the US Centers for Disease Control and Prevention (CDC). ). This is an increase of 10 percentage points from the previous week. For several reasons, including a lack of protection and mutations in the virus, BA.5 may now be difficult to control.

The strength of BA.5 (and its brother BA.4, which makes up about 16% of new cases in the United States, have the same elevated protein mutation as BA.5, but it doesn’t seem to spread that quickly) is their ability to It infects and re-infects almost anyone. This highly contagious strain can evade the immunity that people have built up, both from vaccination and from a previous infection. Like Nature reports, laboratory studies show that even people with so-called Hybrid immunity Vaccination and previous infection with Omicron BA.1 strain are less able to prevent reinfection than BA.4 or BA.5 strain. Experts believe this is largely due to changes in the virus’s spike proteins. current Vaccines And Covid-19 boosters target the original strain of the virus rather than any of the variants, so vaccination doesn’t provide the same protection as before against infection. Fortunately, vaccines still provide adequate protection against the worst outcomes of the disease.

re-infection

Since taking over BA.4 and BA.5, We’ve seen some cases of infection againDr. Wesley Long, an experimental pathologist at Houston Methodist Hospital, told CNN, I’ve seen some re-infections in people with BA.2 in the past few months. This virus combines increased transmission of the virus and increased immune evasion with fewer protection orders across the country, and the risk of infection is high. Conditions are also ripe for the emergence of new variants, as the risk of mutations increases as the virus spreads. In addition, recent research (which has not yet been reviewed) has found that people who were infected again with Covid-19 were at greater risk of hospitalization and death than people who were infected once. They were also more likely to develop new and lasting health problems, including lung and heart problems, fatigue, digestive and kidney disorders, diabetes, and neurological problems.

Vaccines

Vaccine makers are trying to keep up with the virus. On June 30, the US Food and Drug Administration (FDA) said the new fall booster vaccines You should aim for BA.4 and BA.5. But as companies develop new vaccines to deal with microns specifically, it remains unclear how effective they will be in tackling the newer sub-variants or, if the virus continues to evolve rapidly, anything developed now will become obsolete when it becomes available. The good news is that from what experts can tell so far, the BA.5 variant does not cause a more serious form of infection (although scientists are still gathering new data on this), reported symptoms have not changed much and rates of infection and death Hospitalizations in the United States are lower than those in the winter Omicron wave. (This may change, however, as there appears to have been a slight increase recently in hospitalizations, according to the CDC.) Meanwhile, experts recommend that people over 50 years old do not delay taking their boosters, because the risk of infection is now high.
