Epidemiological Profile: What is Rift Valley Fever?
Rift Valley Fever (RVF) is a highly critical, mosquito-borne viral zoonosis that affects both animals and humans. It is caused by the Rift Valley Fever virus (RVFV), classified as a member of the Phenuiviridae family (genus Phlebovirus). First recognized in 1931 during veterinary investigations in Kenya’s Rift Valley, the virus is highly endemic across East, West and Southern Africa.
In livestock herds, particularly cattle, sheep, goats, and camels, RVF manifests as severe epidemics characterized by “abortion storms”—the sudden miscarriage of up to 100% of pregnant animals in a herd—alongside extreme mortality rates in newborn livestock. In adult animals, symptoms can remain mild but cause profound reproductive and physical damage.
Human Vector Vector Transmission Insight
While mosquitoes (primarily Aedes and Culex species) are the environmental vectors that maintain the transmission cycle, the overwhelming majority of human infections are caused by direct physical exposure to the blood, fluids, or organs of infected animals during slaughtering, veterinary procedures, or birthing.

Official Outbreak Response Timeline
The epidemiological curve of the 2026 outbreak in the Southern Region of Malawi is mapped out below. Active clinical surveillance remains underway across the Blantyre Agricultural Development Division (ADD).
Initial Clinical Alerts
Smallholder dairy and beef cattle farmers in the **Thumbwe Extension Planning Area (EPA)** of Chiradzulu begin reporting highly elevated rates of cattle deaths and localized abortion storms in pregnant cows.
Official Lab Confirmation
The Ministry of Agriculture, Irrigation and Water Development officially confirms a localized outbreak of Rift Valley Fever in herds in both Chiradzulu and Mulanje districts.
Statutory Control Orders
Pursuant to powers under the Control and Diseases of Animals Act, authorities announce livestock slaughter bans, hold livestock market permits, and prohibit veterinary post-mortems of suspect cases.
Goat Transmission Confirmed
Surveillance teams confirm localized virus transmission to small ruminants (goats), with at least 3 goat mortalities verified. Cross-departmental One Health sensitisations are launched.
Current Status: Containment Active
Joint taskforces involving Agriculture, Police, and Human Health actors maintain active quarantines. Zero human infections have been confirmed to date due to strict intervention.
Vulnerability Analysis: Why Malawi?
Rift Valley Fever is not entirely new to Malawi. Cross-sectional seroprevalence studies completed between 2020 and 2022 by joint Malawian and international veterinary teams confirmed that RVFV was already silently circulating across multiple ecological zones.
Epidemiological assessments published in peer-reviewed science highlighted specific factors driving high vulnerability in our local communities:
- Rainfall Thresholds: Districts receiving greater than 1,000 mm of annual rainfall are highly prone to seasonal vector populations. Water pooling creates ideal breeding grounds for both Aedes and Culex vector species.
- Mixed-Herd Composition: The presence of mixed cattle, goat, and sheep herds dramatically spikes the vulnerability of virus spread, exhibiting transmission odds up to 10 times higher than single-species grazing.
- Substantial Knowledge Gap: A detailed Knowledge, Attitudes, and Practices (KAP) survey spanning eight rural districts in Malawi demonstrated that only 8.25% of livestock farmers had sufficient awareness about RVF transmission, symptoms, and self-protection models.
Seasonal Peak Warning: The transition period between May and July, which coincides with the conclusion of our long wet season, is identified as the prime seasonal peak for RVF vectors. Vector numbers rise substantially along wetland catchments and dambos.
Official Toll-Free Hotline
Report Suspected RVF
If you observe cattle or goats experiencing high fever, sudden miscarriages (abortion storms), or unusual weakness, immediately notify clinical officers.

Statutory Directives & Interventions
The Government of Malawi has mobilized a joint agricultural-health quarantine network. The following actions have immediate statutory force under the Control and Diseases of Animals Act.
Livestock Slaughter Bans
Complete ban on informal and formal slaughter of susceptible species (cows, goats, sheep) in Chiradzulu and Mulanje. This avoids dangerous exposure to highly infectious animal blood.
Animal Movement Restrictions
Suspension of all movement permits for livestock originating from the Blantyre ADD catchment. Inter-district shipping of hides, raw meat, and manure is heavily restricted.
One Health Field Education
Joint veterinary, medical, and community police units are deployed across markets, EPAs, and school assemblies to build local awareness of safe milk pasteurization and self-protective gear.
Surveillance & Diagnosis
Ongoing blood serum collection and molecular analyses of suspected cases. PHIM laboratories are working with regional centers to secure robust diagnostic assets.
How to Protect Yourself and Your Herd
Direct preventative measures for communities and individual dairy farmers
Strictly Avoid Sick or Dead Carcasses
Do not touch, open, or attempt to butcher carcasses of cattle or goats that have died under unexplained circumstances. Inform veterinary agents immediately.
Pasteurize or Boil All Milk
Never consume raw (unboiled) milk from livestock. Boiling kills the active Rift Valley Fever virus instantly and eliminates contamination hazards.
Vector Control & Insecticides
Use topical mosquito repellents, sleep under long-lasting insecticide-treated bed nets, and dress in light-colored, long-sleeved clothing to block mosquito bites.
Secure Veterinary Protective Equipment
Farmers assisting with livestock birthing or dealing with miscarriages must wear protective clothing, rubber gloves, and simple face masks to shield against aerosol droplets.
