Monthly dengue cases in wet and dry seasons at Muang Nakhon Si Thammarat, Thailand for January 2011- January 2016.
This study investigated climatic factors affecting dengue cases and house index in Nakhon Si Thammarat, Thailand. We randomly selected 32 households, and collected mosquito larvae from indoor and outdoor water containers. We identified Aedes aegypti, and Ae. albopictus larvae up to species level under microscope. We compared dengue cases between wet and dry seasons during 2011-2015. The results showed that dengue cases in the wet season were higher than in the dry season. Relative humidity was positively correlated with dengue cases in this area. From the mosquito larva data collected in March 2016, Muang Nakhon Si Thammarat had house index of 59.38% for Ae. aegypti larvae and 62.50% for Ae. albopictus larvae. This indicated that Muang Nakhon Si Thammarat is the dengue high risk area according to the WHO standard for dengue risk area.

Hello GLOBE Students!

What a great research report! I do have a few questions for you.

1) Do you think there may have been any limitations or sources of error in your research? If so, what?

2) What do you plan to study next and why?

I am very much impressed by your motivation to do this research relevant to your local problem which is enhanced by the global issue of climate change.

It is great you mentioned in your conclusion that you will create awareness about the issue in the community. What would you suggest? Prevention measures or protection measures to be taken by the people to minimize the dengue infection.

the awareness about this case, the community joint the big cleaning campaign every weeks. The activity are survey and inverted container in the house. Bateman's filling sand into the water to shorten the mosquito's life cycle and mosquito net to sleep every night.

The limitations or error sources in my research may be from
1.Some house that we study, We reported that did not have the mosquito larvae, in fact, there may be have mosquito larvae, but because it might be due to a defect in the check result in house index (HI) will be error.
2. The explore of containers sometimes we may be checked not all containers such as Grail rubber containers away from home, the container was placed in the home entirely, which one might have a mosquito larvae result the real numbers of mosquito larvae does not match the number of mosquito larvae that we report
3. When to explore Some of house just pouring water in a container,so we can not know how in the containers with mosquito larvae.
4. When an outbreak occurs, there will be a campaign to prevent or destroy mosquito larvae. Reduce the number of patients display.

We are In progress about>>
1.Survey mosquito larvae in each house for 1 year to confirm conclude the number of mosquito larvae and dengue cases. The important is the investigate about the effects of global warming effects to number of mosquito larvae and dengue cases. Becaues of this year Thailand faced with global warming and El Niño long-standing.
2. We will study the climatic factors in every month , which we collect data of climate from weather station by using weather link program and then we use all climatic factor data that we collect to analysis and find the relationship with dengue cases.
