Lumpy Skin Disease Virus

Understanding Lumpy Skin Disease Virus: A Comprehensive Guide

Lumpy Skin Disease (LSD) is an infectious disease in cattle caused by a virus of the family Poxviridae, also known as the Neethling virus. This disease has significant economic implications, as it can cause permanent damage to the skin of affected animals, lowering their commercial value ¹.

What is the Lumpy Skin Disease Virus?

Lumpy Skin Disease Virus (LSDV) belongs to the family Poxviridae, subfamily Chordopoxvirinae, and genus Capripoxvirus.

The disease is characterized by fever, enlarged superficial lymph nodes, and multiple nodules on the skin and mucous membranes. Infected cattle may also develop edematous swelling in their limbs and exhibit lameness.

How is LSDV Transmitted?

LSDV is transmitted by blood-feeding insects, such as certain species of flies, mosquitoes, or ticks. Understanding how the virus spreads can help eradicate LSDV at its source.

Symptoms of LSDV

The most common clinical symptoms are nodular lesions on the surface of the skin and mucous membranes. These lesions often appear on the outside of infected cattle, such as the head, neck, back, perineum, breast, and other areas of the cattle.

The affected cattle have varying degrees of oedema and lameness in their legs.

Control Measures for LSDV

Control options for the Lumpy Skin Disease Virus include vaccinations and culling of infected animals. In the event of an outbreak, selecting the most effective vaccine to block and eliminate the threat posed by LSDV promptly is the main choice for farmers and authorities.

Impact of LSDV

The lumpy Skin Disease Virus has substantial economic implications. Infected animals tend to have permanent damage to their skin, lowering the commercial value of their hide. Additionally, the disease often results in chronic debility, reduced milk production, poor growth, infertility, abortion, and sometimes death ¹.

FAQs

How can I prevent my cattle from getting LSDV?

Preventing Lumpy Skin Disease Virus (LSDV) in cattle involves several steps:

Vaccination: Vaccination is the most effective means of preventing LSDV. Attenuated vaccines may help control outbreaks.
Control of Insect Vectors: Since Lumpy Skin Disease Virus is primarily transmitted by blood-feeding insects, controlling these vectors can help prevent the spread of the disease.
Movement Restrictions: Restricting the movement of cattle can prevent the spread of LSDV from infected to uninfected areas.
Good Hygiene Practices: Regular cleaning and disinfection of equipment and facilities can help prevent the spread of Lumpy Skin Disease Virus.
Monitoring and Early Detection: Regular health checks and immediate reporting of suspected cases can lead to early detection and containment of the disease.

Remember, it’s important to consult with a veterinarian or a local agricultural authority for the best prevention strategies suitable for your specific situation.

How long does it take for an infected animal to recover from LSDV?

Recovery from Lumpy Skin Diseareasirus (LSDV) in cattle can take several months. This is often due to secondary infections that prolong the recovery period.

In some cases, complete recovery may take up to 6 months. It’s important to note that the recovery time can vary depending on the individual animal’s health status and the care provided during the recovery period.

Always consult with a veterinarian for the best care practices for infected cattle.

What is the mortality rate of LSDV in cattle?

The mortality rate of Lumpy Skin Disease Virus (LSDV) in cattle can vary. While it’s generally low, it can range from 1-5%¹. However, in severe cases, the mortality rate has been reported as high as 75%¹ and even up to 40%².

It’s important to note that these rates can fluctuate based on various factors such as the health status of the cattle, the strain of the virus, and the effectiveness of control measures implemented. Always consult with a veterinarian for the most accurate information.

What is the treatment for LSDV in cattle?

Currently, there are no specific antiviral drugs available for the treatment of Lumpy Skin Disease Virus (LSDV) in cattle. The primary treatment is supportive care, which can include:

Treatment of Skin Lesions: This can involve the use of wound care sprays.
Use of Antibiotics: Antibiotics can be used to prevent secondary skin infections and pneumonia. Secondary infections in the skin may also be treated with Non-Steroidal anti-inflammatory (NSAIDs) and antibiotics (topical +/- injectable) when appropriate.
Care for Affected Cattle: Providing good nutrition and ensuring a clean environment can help the cattle recover.

Remember, it’s always important to consult with a veterinarian for the best care practices for infected cattle.

How can I dispose of an infected animal safely?

Disposing of an animal infected with Lumpy Skin Disease Virus (LSDV) should be done under strict biosecurity processes to prevent the spread of the disease. Here are some general steps you can follow:

Humane Destruction: The infected animal should be euthanized humanely to prevent further suffering.
Safe Disposal: The carcass should be disposed of safely. This could involve burial or incineration, depending on local regulations.
Cleaning and Disinfection: Any areas the infected animal had access to should be thoroughly cleaned and disinfected.
Monitoring: Monitor other animals for signs of the disease and report any suspicions to your local veterinary authority.

Please consult with a local veterinary authority or agricultural department for specific guidelines in your area. It’s crucial to handle this situation carefully to prevent the spread of Lumpy Skin Disease Virus to other animals.

What are the environmental impacts of LSDV?

Lumpy Skin Disease Virus (LSDV) can have several environmental impacts:

Seasonal Outbreaks: In many endemic countries, the incidence of LSDV significantly increases with the onset of seasonal rains and summer season, coinciding with the peak activity of the vectors.
Environmental Contamination: LSDV is stable for long periods at ambient temperature, especially in dried scabs which can contaminate beddings. This can lead to further spread of the disease.
Impact on Wildlife: While LSDV primarily affects domestic cattle, it can also impact wild bovine species. This could potentially disrupt local ecosystems.
Economic Impact: LSDV has significant economic implications as it often results in chronic debility, reduced milk production, poor growth, infertility, abortion, and sometimes death in cattle. This can affect local economies, particularly in regions where livestock farming is a major industry.

Remember, these impacts can vary based on various factors such as the strain of the virus and the effectiveness of control measures implemented.

Conclusion

The Lumpy Skin Disease Virus poses a significant threat to livestock worldwide. By understanding its transmission methods and symptoms, we can better control its spread and minimize its impact on our livestock industry.
