BA 5 Is Driving A Wave Of Covid Infections But Not Deaths—Here’s Why

The evasive BA.5 omicron variant is driving up Covid cases and hospitalizations as it spreads rapidly across the United States—but despite deaths remaining lower compared to earlier waves, experts tell Forbes there are still plenty of reasons to remain cautious and warn Americans against letting their guard down too soon. Increasingly transmissible variants of omicron have surged across the U. S. this year. BA.5, the most infectious form of the virus yet, rapidly spread and became the dominant variant in early July. It now accounts for an estimated 78% of cases, according to the Centers for Disease Control and Prevention and community transmission has spiked. Concerns over BA.5, as well as the related BA.4, prompted officials to direct vaccine makers to target the variants in updated shots and the Biden Administration announced new plans to tackle its spread. Officials and experts say it is especially important to ensure strong protection against serious disease by keeping up-to-date on vaccinations, including booster shots. Despite the appeals of public health officials and being available for many months, booster uptake in the U. S. is poor. Fewer than half of fully vaccinated people have received their first booster dose and fewer than 30% of those who have and are eligible for a second have taken up the offer, according to CDC data. More variants. It is inevitable that SARS-CoV-2, the virus that causes Covid-19, will evolve and spawn new variants over time. Another omicron offshoot, BA.2.75—inexplicably and successfully dubbed “Centaurus” by the internet—has already caught the eye of virologists. The variant is spreading rapidly in India, has been detected across Europe and North America and shows signs of evading immunity. Little data is available and it’s not clear whether BA.2.75 causes more severe disease. It’s also not clear whether it would be able to take over from BA.5 “as the ruler of the roost,” Chin-Hong explained, as they haven’t had a chance to directly compete with each other as yet.”A great deal. Data collection and surveillance is poor compared to earlier on in the pandemic. Individual testing is down, genomic surveillance is reduced and evidence suggests cases could be vastly higher than official figures state. Conversely, hospital figures are inflated and reflect routine testing upon admission, which catches many “incidental” infections from people seeking care for other problems. There is a lot to be understood about the newer omicron variants as well, experts say. BA.5, as well as other more recent omicron offshoots like BA.4 and BA.2.75, are relatively new pathogens that are infecting or reinfecting large numbers of people in the community, Turville explained, which makes it hard to provide absolute and definitive answers. “As with most things with SARS CoV-2, it is a large bag of unknowns,” he added.
