Tick-borne encephalitis in domestic animals.

The research article discusses the occurrence and implications of Tick-borne Encephalitis (TBE) in domestic animals, their impact on human health and strategies to prevent the illness using vaccination.

About TBE and its Reservoirs

• Tick-borne Encephalitis or TBE is a neural infection in humans primarily spread in Europe and Asia through TBE Virus (TBEV).
• The virus primarily exists in reservoir hosts, those including ticks, rodents, and insectivores. Certain domestic animals may also carry this virus.

TBE in Domestic Animals

• In certain domestic species like dogs and horses, TBE infection can cause clinical symptoms that are similar to severe human cases.
• However, other domestic animals such as ruminants (e.g. cattle, goats, sheep etc.) can be infected with TBEV but display no symptoms. These asymptomatic infections pose no health problems to the animals themselves.

Impact on Human Health

• Despite being asymptomatic in ruminants, these TBE infections can pose serious health risks to humans. This is mainly because the virus could exist in the milk of infected animals.
• As a result, consumption of such milk can cause TBEV infection in humans through the alimentary route, making it a significant issue.

Prevention Strategies – Vaccination

• The research article also addresses the development of an experimental veterinary vaccine to combat TBE.
• The proposition here is to vaccinate selected domestic animals to either prevent severe TBE symptoms in animals that are sensitive to it like dogs and horses, or to decrease the alimentary transmission risk in humans from animals like goats and sheep.
