What is Lassa Fever?
Lassa fever is a viral infection caused by Lassa virus and is passed from rats to humans and humans to humans. These viruses are contained in the excrete of rodents, especially rats.
Lassa fever is a severe haemorrhagic illness.
How does Lassa fever occur?
Humans can become infected through exposure to contaminated food or household items. The food can be contaminated with urine or faeces of infected Mastomys rats.
The infection is endemic in the rodent population in some parts of West Africa. The notable places are:
- Mali, Sierra Leone.
There are, however, no records of other West Africa.
The World Health Organisation also confirmed that person-to-person infection. There is also the possibility of a laboratory transmission.
The health agency revealed the real cause of human-to-human transmission. It said in health settings, the absence of adequate disease prevention and control.
“Diagnosis and prompt treatment are essential. The overall case-fatality rate is one per cent. Among patients who are hospitalised with severe clinical presentation of Lassa fever, case fatality is estimated at around 15 per cent. Early supportive care with rehydration and symptomatic treatment improves survival.
“About 80 per cent of people who become infected with the Lassa virus have no symptoms. One in five infections results in severe disease, where the virus affects several organs such as the liver, spleen, and kidneys.”
