2 virus within this genus?
-where is it found?
hosts? is it zoonotic?
reservoir host?

Answer 1

COWPOX + monkeypox
-endemic in only europe and asia
-cattle, cats, humans — ZOONOTIC
reservoir is rodents

Question 2

cowpox in cattle
-how is it transmitted

Answer 2

-from cow to cow is through infected milker’s hands or teat cups
-infected farm cats transmit disease
-rodents transmit also

Question 3

cowpox in cattle
-economic importance

Answer 3

losses due to inconvenience in milking becuase sore teats and mastitis if SECONDARY BACT INFECTION

Question 4

cowpox in cattle
Clinical findings

Answer 4

papules appear on udder and teats, sucking calves may develop lesions in mouth
-vesicles may not be evident or may rupture readily, leaving raw, ulcerated areas that form scabs
-lesions on udder and teats, decrease milk production

Question 5

cowpox in cats
-transmission

Answer 5

-usually skin inoculation, through bite or skin wound, or by rodents
-oro-nasal route is possible
-viral pneumonia is evident

**more prevalent in cats&raquo_space; cattle

Question 6

cowpox in cats
-clinical signs

Answer 6

primary lesions: history of single primary skin lesion, on head, neck, forelimb, can be small scabbed wound to large abscess

secondary lesions: circular, ulcerated papules that are covered by scabs, may show no other skin lesions (scabs are highly contagious), can develop conjunctivitis too, complications from secondary bacT infection

Question 7

cowpox in humans
-transmission
-clinical signs

Answer 7

-direct contact with cuddly cats, rarely from rodents, chance of getting from cow is very low

-macropapular lesions first observed on hands and face, later develop into vesicles and then ulcerative lesions, enlarged painful LN, fever, vomiting, sore throat

-self limiting if no secondary bacT infection

Question 8

monkeypox
-zoonotic?

Answer 8

YES ZOONOTIC

Question 9

monkeypox
-signs
-transmission

Answer 9

-in humans: similar to those with smallpox
-primary infection of humans: direct contact with blood, bodily fluids or rashes of infected animals, handling monkeys, rats or squirrels (rodents are biggest source of spreading, NOT monkeys)
-secondary transmission is human to human: close contact with infected respiratory tract excretions, with skin lesions of infected person or recently contaminated objects

-self limiting unless 2nd bacT infection
