Exams free of charge for students and staff will be offered on 11 April in the secondary San Ysidro, with follow-up on 15 may, in addition to examinations can be ordered through the normal health providers.

So far of 2012 have been 35 cases of tuberculosis in San Diego, while that in 2011 there were 263, reported the HHSA.

Tuberculosis, a disease that was believed eradicated in the United States.UU. and whose world day is held on Saturday, 24 March, impacts in particular in the border area with Mexico, where is located San Ysidro, because more than 50 million crossings per year favor infectious diseases.

Since 2000 occurs an average of more than 300 new cases of tuberculosis each year in the County, of which about 40 per cent are of people born in Mexico, according to the HHSA.

The incidence of tuberculosis in San Diego represents double the average in the United States.UU., what’s puts it as the highest in the nation, and in the case of Tijuana this is 2.8 times the Mexican national average.

Tuberculosis is a chronic, contagious disease that can stay inactive for years after the initial infection, and whose active cases symptoms include night sweats, persistent cough, fever, and loss of weight without apparent reason.

The World Health Organization (who) estimated that 2 billion people, or the third part of the global population, are infected with the bacillus of Koch. Of them, one of every 10 will develop the active and contagious form of the disease at some point in their lives and they lives an average of 10 to 15 people per year if they are not treated properly.
