Cholera outbreak ongoing across southern provinces in Malawi, especially in Nsanje, as of May 30. Use strict food and water precautions.
Event
Malawian health authorities have reported more than 330 cholera cases March 3-May 21 across southern provinces. The most affected province is Nsanje, reporting the majority of cases, followed by Blantyre and Neno. The last cholera outbreak in Malawi occurred in 2019 when only three cases were reported. This represents the complete data available as of May 30.
Context
Cholera is transmitted directly through food or water contaminated with fecal material from an infected person. Most infected people develop no symptoms or only mild diarrhea. However, approximately one in 10 infected people develop severe cholera, which causes symptoms including profuse, watery diarrhea, vomiting, rapid heart rate, low blood pressure, muscle cramps, restlessness, or irritability. Symptoms typically appear 2-3 days after exposure but can develop up to 5 days after exposure. Individuals with severe cholera can develop acute renal failure, severe electrolyte imbalances, and coma. If left untreated, these can lead to shock and rapid death.
Advice
Consult a travel medicine provider before departure regarding cholera vaccination. Practice strict food and water precautions. Seek immediate medical attention if symptoms develop within a week of being in affected areas.
