I am writing about the methods being used to help eradicate the mosquitos that are infected with the Dengue and Malaria virus's. In my village and for the last few months almost every household has had members fall victim to the Dengue virus. What I have notice recently is that there is no fog dispersants being applied to prevent the out breaks. Instead if your home has members that have taken ill do to Dengue, the headman of our village will send a team to that house (only) and spray the insecticide. What is completely puzzling is that the mosquito's just move to the next house and so it seems not only a waste of money and time but no real eradication is taking place and we find ourselves wondering how is this possible when it is obvious that the current methods are not working. We have not had any outbreaks at our home. Not sure why when every home surrounding us has been infected with Dengue. When I approached our headman he tells us that there is no budget to spray all the village.
This leaves me with a few questions
1. Are not the hospitals (that are all full at the moment) coordinating with infected villages
2. The health ministry is not coordinating with areas highly affected by the current outbreak
3. Possible corruption within the villages
I would like to hear from other members in the Chiangmai area if they have experience similar proceedures
Thanks Milt
