TB a hidden threat in the wake of natural disaster

Tracing evacuees exposed to  an 87-year-old woman with active TB at a small, poorly ventilated shelter, the researchers found 20% tested positive to latent tuberculosis infection.

It was not only people in developing countries who were at risk when displaced, the researchers said.

“Displaced populations in industrialised countries may also be vulnerable to communicable diseases after natural disasters,” they wrote.
