H&D - Malaria Management Flashcards
1
Q
information
vaccines
A
- 2 vaccinse recommended by WHO = RTS,S & R21
- creates resistance to the parasite
- R21 has been gven out in 2024 to many ppl in africa
- RTS,S - 18mil doses for 12 countries for use btw 2023-2025
2
Q
information
insecticide treated nets (ITNs)
A
- places around bed at bight = physical and chemical barrier against mosquitoes
- used a tnight when mosquitoes are most active
3
Q
information
indoor residual spraying (IRS)
A
- insecticide being sprayed on internal walls and ceilings
- mosquitoes r endophilic = rest on walls & ceilings while looking for food = receive lethal insecticide dose = die
4
Q
information
rapid diagnostic tests
A
- alternative to examining blood under microscope to check for malaria
- results produced in 20 mins
- once diagnosis condirmed, appropriate drug treatment prescribed
- 3.1 RDTs sold for malaria 2010-2020
5
Q
information
artemisinin-based combinationtherapies (ACTs)
A
- reduce the no of parasites within first 3 days if treatment
- partner drug eliminates remaining parasites
- prevents malaria progressing to severe disease or death
6
Q
information
chloroquine
A
used to treat infections only in places where resistance has not emerged
7
Q
information
malaria chemoprophylaxis for travellers
A
meds given to travellers before entering a malaria-y area
8
Q
information
draining/flushing/removing breeding grounds
A
- breeding grounds = stagnant water in paddy fields or ditches
- flushing land before eggs are laid = decline in no of mosquitoes = reduced transmission
- repairing damaged water pipes
9
Q
information
genetically modified mosquitoes
A
- disabling fertility genes in male mosquitoes = released into wild = no offspring produced when mating
- increasing chance of male being born = less transition by female = pop collapses over time
