The Center for Control and Prevention of American Disease Warning Delta is causing more seriously and spreads easily as chickenpox.

Dr. Rochelle Walensky, Director of the American Disease Control and Prevention Center (CDC), confirming the document leaked on July 29 is correct.

I think people don't misunderstand us too.

Dr. Rochelle Walensky, Director of the American Disease Control and Prevention Center (CDC), during the National Assembly meeting on Washington.

CDC plans to announce documents on July 30 to strengthen Walensky's controversial decision in changing instructions with people who have vaccinated.

We need to apply extreme measures to control the translation, she said, giving or data in the report was not surprising because it was serious synthetic data.

Documents of CDC said Delta strains have the ability to spread similar to chickenpox, with average each infected person will spread for 8 or 9 others.

There are not many diseases with ROs up to 8 or 9, Walensky said.

Important points are contrary to other viruses, who have been vaccinated, whether or not there is a sick or not, if they are infected with the virus, they are still able to spread the same infected people, Dr. Walter Orenstein, head

But the vaccinated person will be safer, because the vaccine helps prevent more than 90% of severe cases, although it may be less effective in preventing infection or spread.

Documents extracting three reports for or transforming Delta can cause serious illness, acknowledging awareness about this war has changed, recommending the vaccine who should wear a mask.

Delta strains made the number of cases in the US increased, especially in small vaccinated areas.

The number of cases we recorded is now higher than any number that has recorded last summer, Walensky said.

CDC's documentation shows a new communication challenge when the number of cases continues to outbreaks, as it is necessary to propagate the community health message, emphasizing vaccination is the best defensive defense against Delta.

US President Joe Biden on July 29 announced a number of new measures to achieve a more immunized American goal, including requiring all federal employees to get vaccinated or disciplined.

This is a tragedy with Americans.
