January 14, 2026 | by Dr. Kenneth A.O

Lassa Fever, Malaria, and Typhoid

Hidden dangers often hide in plain sight in Nigeria’s health landscape. Fever, fatigue, and body aches may signal Lassa fever, malaria, or typhoid, three infections that share overlapping symptoms but demand very different treatments. Misidentifying one for the other can delay care and increase the risk of complications. Early recognition, correct diagnosis, and timely medical intervention are essential for survival and recovery.

This guide explores how to tell the difference between Lassa fever, malaria, and typhoid quickly; highlights risk factors; discusses treatment options; offers practical dietary support; and provides one-week meal plans tailored for Nigeria, Africa, and global audiences. Whether you are a parent, healthcare worker, or traveler, this guide equips you to respond appropriately and reduce risks for yourself and your loved ones.

What Are Lassa Fever, Malaria, and Typhoid?

Lassa Fever

Lassa fever is an acute viral hemorrhagic illness caused by the Lassa virus, endemic in Nigeria and other West African countries. According to the Nigerian Center for Disease Control (NCDC), thousands of cases are reported annually, particularly during the dry season when rodent activity increases

Key points about Lassa fever:

  • Transmitted via exposure to rodent urine or droppings, and sometimes human-to-human contact
  • High-risk areas include rural communities and poorly stored food supplies
  • Symptoms can escalate quickly, requiring prompt medical attention

Malaria

 Lassa fever, malaria, and typhoid

Malaria is a parasitic infection transmitted by Anopheles mosquitoes, predominantly caused by Plasmodium falciparum in Nigeria. Malaria remains one of the leading causes of hospitalization and death in children and adults in West Africa.

Key points about malaria:

  • Symptoms range from mild fever to severe anemia and cerebral malaria
  • Endemic in most parts of Nigeria and Africa
  • Prevention includes mosquito nets, insect repellents, and environmental control. WHO

Typhoid Fever

Typhoid fever is caused by Salmonella Typhi bacteria and is spread through contaminated water, food, and poor sanitation practices. It is more common in urban and peri-urban areas where safe water is limited.

Key points about typhoid:

  • Gradual onset of high fever
  • Abdominal pain, constipation or diarrhea, and sometimes a characteristic rose-colored rash
  • Early antibiotic treatment is essential to prevent complications. WHO

Key Differences in Symptoms

Although Lassa fever, malaria, and typhoid all present with fever, they have distinct features. Understanding these differences can guide when to seek urgent care.

Common Symptoms

Lassa fever, Malaria and Typhoid

All three infections may present with:

  • Fever and chills
  • Fatigue and weakness
  • Headache
  • General malaise

Lassa Fever Symptoms

  • Swelling of the face
  • Bleeding gums or nosebleeds
  • Severe vomiting and diarrhea
  • Abdominal pain
  • Hearing loss in some cases

Expert insight: “Patients often overlook early Lassa fever symptoms, which can progress to bleeding and organ involvement. Early diagnosis is crucial,” – Prof. Chikwe Ihekweazu, NCDC

Malaria Symptoms

  • High fever with chills
  • Sweating episodes after fever spikes
  • Nausea and vomiting
  • Severe anemia or dark urine in advanced cases

Typhoid Symptoms

  • Gradual onset of fever
  • Constipation or diarrhea
  • Abdominal tenderness
  • Rose-colored spots on the torso The Lancet

Risk Factors and Transmission

Cause of Lassa fever is the Lassa virus transmitted by the Mastomys rat

Lassa Fever

  • Exposure to Mastomys rats or their droppings
  • Poor hygiene and food storage
  • Close contact with infected individuals

Malaria

  • Mosquito bites, especially in endemic zones
  • Lack of mosquito nets, repellents, or indoor spraying
  • Stagnant water around homes

Typhoid Fever

  • Drinking or consuming food contaminated with Salmonella Typhi
  • Poor sanitation and handwashing
  • Consumption of street food or raw vegetables

Immediate medical attention is required if you experience:

  • Persistent high fever lasting more than 48 hours

  • Treatment: Artemisinin-based combination therapy (ACT), hospitalization for severe malaria

Typhoid Fever

  • Diagnosis: Blood or stool culture
  • Treatment: Antibiotics (Ciprofloxacin, Azithromycin)
  • Supportive care: Hydration and rest
