It kills about 5000 people every year. Why does Lhasa fever break out every year in Nigeria?

Because the host of this disease is rodents, there is Lhasa fever every year.

Africa has been plagued by many disasters. Some time ago, the biggest locust plague broke out in East Africa, which was decades ago. Today, the disaster continues, and East Africa will face a serious food crisis in the future. Nigeria in West Africa is in dire straits. The first is an unknown mysterious disease. Three weeks ago, Benue, Nigeria reported a new disease. Symptoms of the patient include vomiting, inflammation and diarrhea, and severe cases can die within 48 hours. Preliminary reports say four people were killed. As of February 8th, more than 100 people have been sick and 15 people have died. The Nigerian Centers for Disease Control and Prevention has launched an emergency operation. This unknown disease is suspected to be a new virus, but the test denies this statement. It is not a disease like Ebola hemorrhagic fever.

The authorities have collected samples of local water, sand, fish and plants for inspection abroad. Health officials suspect that this unknown disease may be related to fishing chemicals used by local residents, and an investigation is under way. The mysterious disease just broke out, and the Lhasa fever epidemic on the other side, a serious epidemic in West Africa, was first discovered in Lhasa village, borno state, Nigeria, hence its name. Lassa virus natural reservoir is a rodent, which can spread between humans and primates. It is a very dangerous pathogen and a biosafety level 4 virus.

The incubation period of the virus is usually 3-2 1 day. Most patients have mild symptoms, mainly fever, vomiting, diarrhea, pharyngitis and other symptoms. In severe cases, multiple organ dysfunction and failure can lead to death. The epidemic in Nigeria began in early June, 5438, 2020+10. By February 9th, there were 472 confirmed cases, 708 suspicious cases/kloc-0 and 70 deaths, with a mortality rate of 14.8%. Among the infected people, young people aged 2 1 to 30 are the main ones. In addition, the male-female ratio of the confirmed cases is 1: 1.2. It is reported that the outbreak of Lhasa fever in Nigeria may be caused by rodent infection. Lassa fever can be transmitted through saliva, urine and feces when mice come into contact with people. In the past few years, the Lhasa fever epidemic was the worst in Nigeria, and the number of infected people is still increasing. This is considered as a public health emergency.
