Migrants who came with the caravan are suffering from respiratory infections, tuberculosis, chickenpox and other serious health issues, Tijuana’s Health Department warned on Thursday morning.

The spokesman told Fox News that out of 6,000 migrants currently residing in the city, over a third of them (2,267) are being treated for health-related issues.

There are three confirmed cases of tuberculosis, four cases of HIV/AIDS and four separate cases of chickenpox, the spokesman said.

At least 101 migrants have lice and multiple instances of skin infections, the department’s data shows.
