A student of the university of Franche-Comté has been diagnosed as a carrier of a pulmonary tuberculosis
He is hospitalized at the university hospital of Besançon, and is now in a state of “stable”, announced this Wednesday the regional Agency of health (ARS) de Bourgogne-Franche-Comté.
“Only the forms of the disease affecting the respiratory tract can be contagious,” warns the Institut de veille sanitaire (InVS). The Koch bacillus, the bacteria responsible for tuberculosis, is spread through “respiratory secretions, especially in the case of cough”. Thus, “the risk of contagion increases with the duration of contact and proximity”, complete the ARS.
The Centre of tb control will contact only the people who have been in close contact with the student for at least 8h between September and November.
These will benefit of a free screening (radiology and classical skin test).10% of infected people develop the maladieLes lungs are the prime target of the bacillus, but it can also infect other organs. However, the infection does not necessarily lead to the occurrence of the disease.
Only 10% of infected persons develop tuberculosis in the years that follow. In France in 2015, 4741 cases of tb have been reported to the authorities. More than 3400 of them were pulmonary cases.
A proportion down virtually constant since the 1970s. However, regional disparities and social persist. The Ile-de-France, Guyana and Mayotte are departments that are most affected by this infectious disease. The precarious populations such as the homeless and migrants from poor countries are the most affected. Overcrowding, malnutrition and unsanitary living conditions promote the “awakening” of the bacillus and the onset of the disease. According to the latest epidemiological data in france, nearly 6 tb cases in 10 are reported in people born abroad. They come mainly from sub-saharan Africa and the North. Patients who do not always have access to the health care system, which hampers access to treatment and follow-up.
However, the good adherence to the long treatment of 6 months is essential for healing.
The poor monitoring of the treatment also promotes the emergence of multidrug-resistant disease. Frequent in the countries of eastern Europe, these multidrug-resistant spread in France. In 2015, 98 drug-resistant strains have been identified, as compared to 50 in 2010. A proliferation which threatens the global objective of eradicating the disease by 2030.
