Flashcards in emerging viruses Deck (18):
1

factors contributing to emergence of new viral diseases

population density, travel, changes in social behavior, environment, industry, changes in microorganisms

1

emergence of hantavirus due to

increased contact with mice due to rainfall, foodsource, increased mouse population

1

symptoms, monkeypox

headache, rash, swollen lymph nodes, backache, fatigue > 3 days > crusting, scabbing of > 3 weeks

2

wild nile and dengue are members of ____ family

flavivirus

3

transmission dengue (hemmoragic) fever

mosquito to human (urban) or monkey

4

emergence monkeypox due to

pet choice changes, movement of virus and reservoir into new areas of commerce

6

second infection, with new dengue virus serotype > Hemmoragic fever and dengue shock syndrome =

non neutralizing antibodies causes macrophage infection > cytokine release. Rupture of vasculature, internal bleeding, palsma loss, shock

7

diagnosis dengue hemmorhagic fever

postive tourniquet test, immunofluorescence for viral antigen

8

disease caused by hentavirus

Hentavirus-induced (cardio-)Pulmonary syndrome, leading to pulmonary edema, death

8

emmergence of West nile and Dengue due to

increased range of vector (dengue) introduction of virus resevoir into new area (westnile)

9

diagnosis of west nile virus

local WNV activity in area, adults 50 age or older with unexplained encephalatis or meningitis in late summer/fall

11

arboviral encephalatis transmission

reservoir in birds, arthropod spread between birds, horse or human dead end host

12

Arbovirus 3- types diseases

fever+macupapular rash, OR encephalatis, OR hemmoragic fever

13

clinical features west nile fever (severe)

fever, ataxia, myelitis, change in mental status, GI, seizures

15

incubation time, monkeypox

12 days

16

clinical features west nile fever (mild)

fever, fatigue, swollen lymph glands, headache, skin rash on trunk eye pain

17

falvirus morphology

enveloped, single strand RNA

18

initial infection with dengue/hemmorhagic fever serotype virus causes

breakbone fever, joint pain, muscle/bone pain, fever, lympahdenopathy
