Toga Flashcards
Togaviruses are transmitted by mosquitoes
T
The clinical appearance of togavirus infection is dose dependent
T
Several togaviruses are zoonotic agents
T
In the geographic distribution of equine togavirus migratory birds have an important role
T
Rodents serve as reservoirs for the Western equine encephalomyelitis virus
T
Equine encephalomyelitis viruses are zoonotic
T
In the geographic distribution of equine togavirus migratory birds
Equine encephalomyelitis viruses can cause asymptomatic infections
T
Birds serve as reservoirs for the Eastern equine encephalomyelitis virus
T
Equine encephalomyelitis viruses can cause lameness in horses
T
In Venezuelan horse encephalitis enteric symptoms can be observed too
T
An early sign of Eastern encephalomyelitis is biphasic fever

Wild birds are involved in the transmission cycle of eastern equine encephalomyelitis
T
In endemic countries vaccines are available against equine viral encephalomyelitis
T
Some strains of Venezuelan horse encephalitis virus can be transmitted from horse to other hosts
T
Vaccination of horses in the Americas is used to prevent togavirus infections.
