MADISON (WKOW) The Wisconsin Department of Health Services said the BA2 Omicron sub-variant is now responsible for the majority of new COVID-19 cases in the United States.
The number of cases is slowly increasing, but we have not seen a major increase in the US since January.
China’s largest city, Shanghai, is the epicenter of the recent Omicron rise, and doctors report that several factors have affected this outbreak, as has a vaccine type. China primarily uses Sinopharm and Sinovac vaccines.
“They are not nearly as effective as the mRNA vaccines, and they are the ones they have used exclusively in China,” said Dr. Ottenbaker | SSM Health Wisconsin VP of Outpatient Clinical Programs.
Sinopharm and Sinovac vaccines use an attenuated or inactivated form of COVID-19 to trigger immunity, which UW Health Infectious Diseases Specialist Dr. James Conway says has one major drawback.
“They really do not like these new variants very much, which is why they have had to turn around very quickly to either try to get their fingers on some of the genetic vaccines,” said Dr. Conway.
Pfizer and Moderna are the genetic vaccines used primarily in the United States, which doctors said can be adjusted to protect against coronavirus variants.
“The great thing about these genetically engineered vaccines, the mRNA and DNA vaccines we have, is that they can actually be updated pretty quickly,” said Dr. Conway.
Doctors also reported that China’s strict ‘Zero Covid’ strategy, which is mass testing, contact tracking and isolation of those infected, does not adapt as the virus changes.
America’s COVID strategies, such as masking and testing, have been far less restrictive than China’s ‘Zero’ policies, which doctors say have proved costly.
“It resulted in us having more cases during the whole pandemic, maybe a higher percentage of people you know get really sick and die of Covid. I think we could see an increase in cases, at this point in the pandemic , with vaccination rates where they are, “said Dr. Jeff Pothoff, UW Health Chief Quality Officer.
New cases of COVID-19 are on the rise in Wisconsin.
However, the CDC still lists all counties in the state as having a low level of society.
