World's deadliest disease hits New York high school.

Thanks to #Biden's unvetted #illegal migration?

Most tuberculosis cases in the US are imported or due to migration into the country, the CDC says, with the vast majority of cases reported nationally diagnosed in people who were not born in the country.

#Tuberculosis is highly infectious, spread via droplets released in coughs and sneezes that hang in the air for hours after an infectious patient passes.

In some cases, the disease can lie dormant in the body for years, but in others it triggers a quick infection that attacks the lungs.

Symptoms begin as a cough that lasts for three weeks or more and coughing up blood before progressing in untreated cases to respiratory failure, or being unable to breathe, and death.
