Transmission of capripoxvirus
Research in Veterinary Science
|September 1, 1985
Summary
Capripoxvirus spreads to sheep via aerosols and contact with infected sheep and goats. Transmission speed depends on the severity of clinical signs in infected animals.
Area of Science:
- Veterinary Virology
- Infectious Diseases
Background:
- Capripoxvirus (CPXV) causes significant economic losses in livestock worldwide.
- Understanding CPXV transmission dynamics is crucial for disease control.
Purpose of the Study:
- To investigate the transmission routes of capripoxvirus in sheep and goats.
- To determine the incubation period and factors influencing CPXV transmission rates.
Main Methods:
- Experimental transmission using aerosolized CPXV isolates from Yemen.
- Contact transmission studies with sheep and goats exposed to CPXV isolates from various geographic locations (Yemen, Sudan, India, Nigeria).
Main Results:
- Capripoxvirus transmission was confirmed via aerosol and direct contact in sheep and goats.
- The incubation period for CPXV infection ranged from approximately 8 to 12 days.
- Animals with pronounced clinical signs exhibited more rapid CPXV transmission compared to those with peracute or mild disease.
Conclusions:
- Both aerosol and contact are effective routes for capripoxvirus transmission.
- Clinical presentation influences the rate of CPXV spread within susceptible populations.
- These findings highlight the importance of biosecurity measures to prevent CPXV outbreaks.
