MIAMI ā The new COVID-19 sub-variants, BA. 4 and BA.5 are behind the latest new surge in South Florida.
The new variants originate from South Arica and are now in South Florida.
The Premier Medical Laboratory Services, said they found three cases in Miami-Dade.
āThey are much more transmissible and infectious in individuals than all the previous strains that weāve seen,ā FIU Infectious Disease Expert Dr. Aileen Marty said.
Dr. Marty said the difference is that now more people have significant immunity, but over time, that immunity drops and opens up the door to the new sub-variants which seem to have less difficulty entering our cells.
āBA.4 and BA.5 replicate more efficiently within our cells so we produce more virus. therefore weāre shedding a lot of viral material that other people can be infected with,ā Dr. Marty said.
This is the reason why the positive COVID-19 numbers are going up.
In Miami-Dade the positivity rate is 22 percent and in Broward itās almost 23 percent.
However if youāre vaccinated and boosted youāre likely not going to end up in the hospital.
ā76 percent of the cases in our hospitals right now are people who have never been vaccinated,ā Dr. Marty said.
Back on May 23, the Jackson Health Care System had 84 COVID-19 patients, now that number has gone up to 137.
āWeāre again seeing an increase but the severity is not so, so bad,ā Jackson Memorial Chief Medical Director Dr. Hany Atallah said.
Both doctors agree, people must be vigilant when it comes to COVID-19 and strongly suggest getting vaccinated.
