Can The Delta variant loads even in vaccinated?
A study by the U.S. Center for Disease Control and Prevention (CDC) found that the Delta variant of Covid causes a similar viral load in vaccinated and non-vaccinated individuals.
The study is based on 469 Covid
cases found among Massachusetts residents who traveled to Barnstable County for
a summer vacation between July 3 and 17, 2021. Of these, 346 (74%) were fully
vaccinated. Delta variants were found in 90% of the samples taken from 133
patients.
Cycle threshold (CT) values were
similar in samples of patients who were vaccinated and those who were not. The
CT value is a measure of how quickly the SARSCOV-2 virus can be detected in a
sample during RTPCR testing. It calculates the frequency at which the viral RNA
in the sample must be amplified in order to reach a detectable level. The
similar CT value in both groups indicates that the viral load is similar.
People with high viral loads are
also more likely to spread the disease to others. Covid is different from other
variants in people who have been vaccinated against the Delta virus. In the
light of the study, CDC Director Rochelle Valensky pointed out that it can
spread.
The findings of this study prompted the CDC to revise its guidelines on mask use. The CDC initially suggested that vaccinated people should not wear masks in public places, and later recommended that everyone wear the mask in public places such as schools and offices.
