Malignant catarrhal fever is a dangerous viral disease that affects cattle, buffalo, and some other animals. Farmers often face big losses when this illness appears in their herds. It spreads quickly, and many animals are unable to survive. To protect livestock, it is essential to understand what malignant catarrhal is, how it spreads, the signs to look for, and the most effective ways to manage it.
This article will explain malignant catarrhal in simple words. You will learn its causes, symptoms, risks, and prevention methods. With the right knowledge, farmers and animal owners can act early and reduce damage.
What Is Malignant Catarrhal Fever?
Malignant catarrhal fever is a viral disease that affects cattle and other animals. It is caused by a type of herpesvirus that usually lives in sheep and wildebeest without harming them. However, when this virus passes to cattle or buffalo, it becomes deadly.
- The disease is not common, but when it strikes, the effects are severe.
- Animals may get sick suddenly and die within a few days.
- Farmers often lose valuable livestock before they can respond.
Malignant catarrhal is not just a health issue. It is also an economic problem. Farmers lose income when their animals die, and the community loses important resources like milk and meat.
Causes of Malignant Catarrhal Fever
The main cause of malignant catarrhal fever is a virus. This virus usually lives harmlessly inside sheep or wildebeest. These animals act as carriers. They do not get sick, but they spread the virus.
Cattle or buffalo become infected when they come into contact with:
- Sheep, especially during lambing season
- Wildebeest, especially when calves are born
- Saliva, nasal fluids, or even droplets from infected animals
The disease does not spread from cow to cow directly. Instead, it spreads from the carrier species to cattle. This makes controlling contact between different animals very important.
Symptoms Seen in Infected Animals
The signs of malignant catarrhal fever are very strong and appear quickly. Farmers must know these symptoms so they can act fast.
Common symptoms include:
- High fever that does not go away
- Runny nose with thick discharge
- Red and cloudy eyes, sometimes leading to blindness.
- Sores inside the mouth and nose
- Difficulty in breathing and eating
- Weakness and sudden death
Some animals may show nervous signs such as shaking or acting restless. Because the disease is fast, farmers must watch their herds daily.
How Malignant Catarrhal Fever Spreads
The spread of malignant catarrhal fever depends on the presence of carriers like sheep and wildebeest. The virus is mainly shed during the birthing season. Lambs and wildebeest calves carry a high load of the virus, which makes cattle at great risk.
Ways the virus spreads include:
- Direct contact with carrier animals
- Sharing grazing areas where infected animals stay
- Breathing in droplets when animals are close together
- Contact with feed, water, or grass contaminated by carriers.
Because the virus survives only for a short time outside the body, spread happens mostly through close contact.
Risks to Farmers and Animal Owners
Malignant catarrhal fever causes more than animal sickness. It creates serious risks for farmers and communities.
- Economic loss: Farmers lose valuable cattle and buffalo, which affects income.
- Food security: Less milk and meat production impacts the local food supply.
- Breeding problems: Death of animals reduces herd growth and long-term farming plans.
- Emotional stress: Losing animals can be very painful for families who depend on them.
When farmers face repeated outbreaks, they may feel hopeless. This is why education and prevention are so important.
Treatment Options for Malignant Catarrhal Fever
Sadly, there is no specific cure for malignant catarrhal fever. Once an animal shows severe symptoms, recovery is very rare. Most treatments are supportive, meaning they help reduce suffering but cannot remove the virus.
Supportive care may include:
- Giving fluids to prevent dehydration
- Providing soft feed that is easy to eat
- Reducing stress by keeping animals in quiet places
- Using medicines to control pain and fever
Veterinarians often advise removing sick animals from the herd to stop further spread. While treatment cannot save most animals, good management can reduce losses.
Prevention and Control Measures
Since there is no cure, prevention is the best way to control malignant catarrhal fever. Farmers must focus on management practices that lower the chance of infection.
Key steps include:
- Keeping cattle away from sheep and wildebeest, especially during birthing seasons
- Using separate grazing areas and water sources for different species
- Reducing stress in animals to help maintain strong immunity
- Regular health checks to identify sick animals early
In some regions, vaccines are being studied, but there is no widely used vaccine yet. Until then, biosecurity and separation remain the best tools.
Malignant Catarrhal Fever and Wildlife Connection
Wildlife plays a major role in the spread of malignant catarrhal fever. In Africa, wildebeest are common carriers. In other parts of the world, sheep play this role. Farmers living close to wildlife reserves or sheep farms face higher risks.
- Wildebeest calves carry the virus at high levels for several weeks after birth.
- Sheep shed the virus during lambing season.
- Cattle that graze near these animals often get sick during these times.
This shows how farming and wildlife management are connected. Healthy cooperation between farmers and wildlife managers is important to reduce outbreaks.
Impact of Malignant Catarrhal Fever on the Livestock Industry
The livestock industry suffers heavily when malignant catarrhal fever appears. Even though outbreaks may be small, the losses are large.
- A single outbreak can kill many cattle in a short time.
- Farmers lose income, which affects the entire supply chain.
- Export and trade can also be affected if regions are marked as risky for disease.
This makes malignant catarrhal not only a farm issue but also a national agricultural challenge. Strong monitoring systems are needed to protect both farmers and the economy.
Future of Research on Malignant Catarrhal
Scientists are working to find better solutions for malignant catarrhal fever. Research is focused on:
- Developing safe and effective vaccines
- Creating better tests to detect the virus early
- Studying the role of wildlife in spreading the virus
- Finding ways to boost immunity in cattle and buffalo
With ongoing research, farmers may one day have stronger tools to fight this disease. For now, prevention and awareness are the best protection.

FAQs about Malignant Catarrhal Fever
Malignant catarrhal is a deadly viral disease that affects cattle, buffalo, and some wild animals. It comes from a herpesvirus that usually lives in sheep or wildebeest without harming them. When passed to cattle, it causes severe illness and often death.
Animals usually get malignant catarrhal fever by being close to sheep or wildebeest, especially during lambing or calving season. The virus spreads through saliva, nasal fluids, and droplets from carrier animals.
No, malignant catarrhal does not spread directly between cattle. It only spreads from carrier animals like sheep or wildebeest to cattle or buffalo.
There is no cure for malignant catarrhal. Most animals that get sick do not survive. Treatment is supportive only, helping reduce pain and stress but not removing the virus.
No, malignant catarrhal does not affect humans. It only affects certain animals, mainly cattle, buffalo, and some wildlife.
Conclusion
Malignant catarrhal fever is a deadly viral disease that affects cattle and buffalo. It comes from viruses carried by sheep and wildebeest. There is no cure, and most infected animals die. Because of this, prevention is the only real way to protect herds.
Farmers must keep cattle away from carrier animals, especially during birthing seasons. They must also watch for symptoms such as fever, eye problems, and nasal discharge. With awareness, separation, and good management, the damage caused by malignant catarrhal fever can be reduced.
- Malignant catarrhal spreads from carriers like sheep and wildebeest.
- Symptoms are severe and include fever, runny nose, and eye damage.
- There is no cure, only supportive treatment.
- Prevention through separation and biosecurity is the best method.
By learning about malignant catarrhal and acting early, farmers can protect their animals, their income, and their future.
