CDC says vaccinated people can spread delta

The CDC conducted a study on a COVID-19 outbreak in Massachusetts, revealing that vaccinated individuals infected with the Delta variant have similar viral loads to unvaccinated people, influencing mask-wearing guidelines. A Chinese study found Delta patients have significantly higher viral loads and shorter incubation periods. A CDC report indicates Delta is more transmissible and causes more severe illness, but vaccines remain effective in preventing serious disease.

What was a key finding of the CDC study regarding vaccinated individuals infected with the Delta variant?

• They have lower viral loads than unvaccinated individuals.

• They cannot transmit the virus to others.

• They have similar viral loads to unvaccinated individuals.

• They do not need to wear masks indoors.

According to the CDC, what change was made to mask-wearing guidelines for vaccinated people?

• Masks are optional in all settings.

• Masks are no longer required indoors.

• Masks are only required outdoors.

• Masks are recommended indoors in areas with significant virus spread.

What did the Chinese study find about the viral loads of Delta variant patients compared to the original COVID-19 strain?

• Delta variant patients have lower viral loads.

• Delta variant patients have similar viral loads.

• Delta variant patients have no viral loads.

• Delta variant patients have viral loads 1000 times greater.

How does the transmissibility of the Delta variant compare to the original COVID-19 variant according to the CDC report?

• It is not transmissible at all.

• It is up to three times more transmissible.

• It is equally transmissible.

• It is less transmissible.

What is the main reassurance provided by the CDC regarding vaccines and the Delta variant?

• Vaccines prevent over 90% of serious disease.

• Vaccines are ineffective against the Delta variant.

• Vaccines cause more severe illness.

• Vaccines are only effective for a short period.
