Tijuana health officials have said that of those migrants in the caravan at the United States’ border with Mexico, about one third is being treated for health concerns. Migrants who came with the caravan are suffering from respiratory infections, tuberculosis, chickenpox, and some other serious health issues, Tijuana’s Health Department warned on Thursday morning.

A spokesman for the Tijuana Health Department 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 several migrants who have contracted serious diseases that are life-threatening. So far, there have been three confirmed cases of tuberculosis and four cases of HIV (human immunodeficiency virus)/AIDS (advanced immunodeficiency syndrome). Lesser illnesses that pose little threat to life include four separate cases of chickenpox, the spokesman said. And at least 101 migrants have lice and multiple instances of skin infections, the department’s data shows, according to a Fox News report.

There’s also a looming threat of a Hepatitis outbreak due to unsanitary conditions in and around the shelter caused by the migrants, the spokesman said.  The location also has only 35 portable bathrooms and a sign reading “No Spitting” had to be put up because coughing and spitting by migrants are rampant in the shelter.

There are thousands of migrants being sheltered at the Benito Juarez Sports Complex near the San Ysidro U.S.-Mexico Port of Entry, despite the place being capable of providing for 1,000 people.

Tijuana’s Mayor, Juan Manuel Gastelum. said Tuesday that the city only has enough money to assist the migrants only for a few more days, with the city saying it’s spending around $30,000 a day. “We won’t compromise the resources of the residents of Tijuana,” Gastelum said during a press conference. “We won’t raise taxes tomorrow to pay for today’s problem.” It’s difficult to say what the lack of funding will mean for the migrants at this time.

Despite the disturbingly disgusting conditions most of the migrants find themselves in today, most are still committed to entering the U.S. A few have “self-deported” and others have been deported by Mexico, but there are thousands remaining determined to cross the border at all costs.
