|
|
|
Dengue fever is detectable in the blood in the acute phase within __ days of onset, or by specific antibodies in convalescent phase serum obtained __ days or more after onset of illness.
|
5 days, 6 days
|
|
|
what is the most commonly used serological procedure for diagnosis and is particularly suitable for high-volume testing.
|
The IgM capture ELISA
|
|
|
True or false? The viruses of dengue fever are flaviviruses.
|
True
|
|
|
What is the mode of transmisssion for dengue fever?
|
Infected mosquitoes, principally aedes aegypti mosquito.
|
|
|
The aedes aegypti mosquito is a day biting species, with increased biting activitiy for how many hours after sunrise and several hours before sunset?
|
2 hours after sunrise
|
|
|
What is the incubation period for dengue?
|
From 3 to 14 days, commonly 4-7 days
|
|
|
What is the period of communicability for dengue?
|
No direct person to person transmission.
|
|
|
Patients are capable of passing dengue to mosquitoes from shortly before the febrile period to the end therof, usually __ to __ days.
|
3 to 5 days
|
|
|
True or False? Adults tend to have milder dengue disease than children.
|
False, children tend to have milder disease.
|
|
|
How many serotypes are reviewed in this reference for dengue fever?
|
the answer is 8 (1,2,3,4,-1,-2,-3,-4)
|
|
|
True or False? Recovery from infection with one serotype provides lifelong homologous immunity but only short term protection against the other serotypes and may exacerbate disease upon subsequent infections.
|
True
|
|
|
Do or Don't? Isolate infected patients.
|
Do! because the mosquitoes ae the vector, isolate the patient use mosquito nets and insect repellant to prevent the spread.
|
|
|
True or false? If dengue occurs near possible jungle where theres yellow fever, don't immmunize for yellow fever.
|
False, immunize for yellow fever because the urban vector for the two disease are the same.
|
|
|
What's the specific treatment for dengue fever?
|
Supportive, including oral rehydration. Acetylsalicylic acid (asprin) is contraindicated because of its hemorrhagic potential.
|
|
|
What are the epidemic procedures for dengue fever.
|
"1) Search and destroy Aedes mosquitoes in sites of human habitation, and eliminate or larvicde to all potential Ae. aegypti larval habitats.
2) Use mosquito repellents for people exposed to vector mosiquitoes" |
