If you take the function to be the expert of medical entomologist, what is your plan and actions to support and react for the situation below?
1. Routine work of vector surveillance for malaria
Malaria is spread to people through the bites of infected female Anopheles mosquitoes
which is an acute febrile illness caused by Plasmodium parasites. There are 5 parasite species that cause malaria in humans including Plasmodium falciparum, Plasmodium malariae, Plasmodium vivax, Plasmodium ovale, Plasmodium knowlesi.
what, where, when(how long), why, do you want to do? Because of all of these must have under money to manage. You might to think the important, appropriate and worthiness that want to do.
-What do you do in the field and laboratory.
-How to get the data
-How to analysis
-How to conclusion and interpretation the result
-How to monitoring and control in the long term
2. There is the outbreak of malaria in Thai-Myanmar border in Tak province.
Please explain the detail in term of
*To track malaria vector densities (for selection and timing of vector control malaria program)
*To investigation effective and responsive to any threats to a successful control and elimination program.
– Planning (Under funding)
*Where is you want to surveillance? (You must to think about that area have problem malaria such as case report, Resting place and breeding place of vector, transportation of people)
*What time you want to go?
*What do you do?
*How do you do?
*How do you get the data?
All of these you must to think and good planning before go to the real situation
– Program activities
*To collecting mosquitoes for outdoor and indoor (what’s time, what’s stage mosquitoes of do you want for you to the appropriately method)
*Preparing instrument/equipment for various techniques
*Collection techniques for adult
Biting collection: – baited catches (landing catch, animal-baited net)
Resting collection:- indoor resting (pyrethrum spray sheet, aspirator)
– outdoor resting: direct (aspirator, sweeping net), indirect (artificial shelter)
Trapping collection: – light trap, sound trap, gravid trap
*Collection techniques for immature collections
Netting: hand nets
Siphoning: rubber tubes
Special techniques: Uproot, cylinder (Mansonia)
*Record the data including date, place(coordinates), time, sample, etc.
*If you want preserving and handling mosquitoes for study in the future about morphology you should do the appropriately method for killing and preserving. Killing method by Cold at 4 ºC or-20 ºC or Killing Jars/Bottles. Preserving method by Ethanol (grain or ethyl alcohol) mixed with water (70 to 80 percent alcohol) is usually the best general killing and preserving agent.
*How to control/stop the outbreak?
– Education to villagers/traveler
– Protection from mosquitos bite (Wear long-sleeved clothing and long pants, Use a mosquito net, Spray
an insecticide or repellent)
– Eliminate breeding places
When you get the raw data you can bring to analysis or record with Microsoft for generate the data what do you want.
The last step can conclusion and interpretation the result so led to what is the next step in the present or the future (what do you have to do).
