About Lassa fever
- It is a zoonotic disease endemic to parts of west Africa.
- Causes : It is caused by the Lassa virus, a member of the Arenaviridae family.
- Transmission : It’s transmitted through the urine and droppings of infected multimammate rats found in most tropical and subtropical countries in Africa.
- They are able to contaminate anything they come in contact with.
- The Lassa virus spreads through human to human contact with tissue, blood, body fluids, secretions or excretions.
- This includes coughing, sneezing, kissing, sexual intercourse and breastfeeding. In hospitals the disease is spread through contaminated equipment.
- Fatality rate : The fatality rate for hospitalised patients is generally high and can reach 80 per cent at times.
- Vaccines and Treatment : There is currently no vaccine approved to prevent the disease.
- Antiviral drug ribavirin is often used to treat Lassa fever although the usage is not a licensed treatment.
- Other procedures used are supportive care including hydration, oxygenation, and treatment of specific complications arising due to the disease. Preventive vaccines are currently under research and development.
