According to estimates from the Centers for Disease Control and Prevention, the BA.5 omicron subvariant is now the dominant coronaviruses strain in the US, as cases rise and drug companies work to reformulate.
The intensive care unit has a nurse in it.
70% of coronaviruses infections for the week ending July 2 were caused by BA.5 and the closely related omicron substrain.
The BA.2.12.1 variant accounted for 27% of Covid-19 cases last week.
The news comes a week after the Food and Drug Administration recommended that pharmaceutical companies update their coronaviruses vaccine booster shots by the fall in preparation for a winter surge.
In the week ending July 4, the United States averaged 94,345 new infections per day, more than triple the 30,558 daily cases reported as of April 10.
In the seven-day period ending July 3, Covid-19 hospital admissions averaged 4,376 per day, more than double the average of 1,428 per day in early April.
According to the CDC, over 16% of U.S. coronaviruses tests came back positive on average last week.
Omicron substrain BA.2 remained the dominant variant for several weeks after the strains became dominant in South Africa. Data suggests that BA.5 is even better at evading the immune system than the other two substrains because they have different spikes in their virus that help them evade the immune system. The United Kingdom has seen a spike in cases of the coronaviruses BA.4 and BA.5. Two weeks ago, the dominant Covid-19 substrains in the US were BA.4 and BA.5.
There was a continued increase in Covid-19 cases. The director of the Center for Virology and Vaccine Research at Boston's Beth Israel Deaconess Medical Center told the Wall Street that there has been a rise in the number of new subvariants that are more contagious than previous strains.
When you should get your next shot is when the FDA recommends covid boosters.
There is a lot of confusion about the newest, most contagious omicron subvariants.
