Machine translated from French An extremely rare virus in the Northern Hemisphere because it is endemic to West Africa, there are no vaccines yet to counter Lassa fever. On May 2, 2024, because he was suffering from Lassa fever, a man was admitted to the Bégin military hospital in Saint-Mandé in Val-de-Marne (94). If his condition was quickly stabilized and the symptoms treated, an investigation is currently underway to notify all the people with whom he may have recently come into contact.
As soon as they are known to health services, they will be placed under surveillance in order to intervene as quickly as possible when symptoms appear.
What is Lassa fever?
If we refer to the definition given by the WHO, Lassa fever is one of the hemorrhagic fevers. So, it is a type of disease that can lead to death due to the resulting bleeding symptoms.
Endemic to West Africa, the Pasteur Institute estimates, in its disease sheet dedicated to it, that between 100,000 and 300,000 people are infected each year in this region of the world.
