The disease came to Normandy



Normandy combines controlled areas for cattle tuberculosis. In January, seven new cases emerged in this region. In detail, six people were identified, including Calvados & # 39;; Western France November 8th. All contaminated flocks were slaughtered this summer. "This is a strain of beef tuberculosis that was thought to have been abolished twenty-five years ago, adan said Etienne Gavart, director of the GDS (sanitary defense group) of Calvados.

Extension of the struggle area

Prior to Normandy, the animal health (ESA) epidemiological surveillance platform had outbreaks of tuberculosis in France in 64 regions, including 58 (91%) in the new Aquitaine. Cases were found at Charente, Charente-Maritime, Corrèze, Côte d'Or, Dordogne, Haute-Corse, Haute-Vienne, Gironde, Landes, Lot-et-Garonne. and Pyrénées Atlantiqueséte.

Now, facing the rise of this disease, the government wants to shift to a gear. In addition, a major launch campaign started in early November and will end next April. It should test 51 000 animals of 850 farms in Calvados and 50 000 animals in the Orne 700 farm. Even though no cases have been identified yet, measures will also be taken in the Channel, where 35,000 animals will be identified from 419 farms.

Animal tuberculosis causes 2% of human cases

In the southwest, particularly affected, wildlife surveillance, the probable disease reservoir, began in France in 1011. Because Hexagonal tends to continue to benefit from the status of ”officially without beef tuberculosis Çünkü. bovine "We must not exceed 200 positive cases per year. We have a face. It is far away from the 60's, the 25% of the herd is affected …" says Yeil Gavart Western Francto.

However, there is no need to worry about human infection, but only 2% of human tuberculosis cases in France come from animal tuberculosis. Bacterial-caused infection in cattle Mycobacterium bovis by inhalation, often invisible. Indeed, with a very long evolution, clinical symptoms appear too late, and they explain ANSES on their website. The general condition of the animal may vary: it will therefore show signs of delicacy or a decrease in production. However, most of the time, after death, it is seen that the disease is identified during autopsy or medical examination.

About a third of the world's population is infected without knowing it

In humans, tuberculosis usually attacks the lungs, sometimes kidneys, ganglia and bones. There are three forms of tuberculosis: pulmonary, spreading, or shafts combining 70% of cases, bones, kidneys, lymph nodes, meninges, or extra pulmonary and two affecting the central nervous system. others.

Currently, about 1/3 of the world's population is infected with bacteria, most of which are not affected by the immune system infection. Therefore, no symptoms are seen in people with a latent infection and are not contagious. On the other hand, if the immune system weakens, bacteria can multiply and cause disease. However, this is rarely seen because only 5% to 10% of the infected people in the world are sick according to the World Health Organization.

Secondly, mostly in poor countries, tuberculosis develops in regions with malnutrition, poor hygiene, overcrowding and lack of medical follow-up. In addition, patients are usually treated too late, which will cost them their lives. In 2017, 1.6 million people died of tuberculosis. Therefore, at the end of September, the United Nations gathered in New York to collect $ 1.3 billion in hopes of eliminating concern by 2030 and easing drug intake at a lower cost. .
