The first 100 days after taking office are when residents watch a new leader most closely, and when that leader has the most momentum. This guide turns Aedes mosquitoes and dengue into a 100-day work plan a mayor can read in five minutes, forward to the chief administrator and the public health division, and act on immediately. It also shows exactly where the right government mosquito control equipment fits into that plan.
Somchai (a fictional name) has just become mayor of a Subdistrict Administrative Organization in central Thailand, a place that is half town and half countryside. It has about a dozen villages, two new housing estates, three primary schools and a busy Wednesday market. During the campaign he talked about roads, tap water and care for the elderly. Mosquitoes barely crossed his mind.
On the morning of his 23rd day in office, a teacher calls to say two pupils have been admitted to hospital with high fever and the doctor suspects dengue. By the afternoon a parent has posted in the subdistrict Facebook group: "Same thing happened last year and nobody came to spray." The post is shared dozens of times before dark.
Somchai calls an urgent meeting. He learns that the office owns two thermal foggers. One has not started for months. The other runs, but its barrel is corroding. The officer who used to do the spraying has transferred elsewhere. Chemical stock is low. Nobody can say exactly where the two children live on a map, what radius should be sprayed, or how residents should be informed.
The team finally goes out the next day with the one working machine. It stalls several times and needs repairs along the way. Online, people keep asking why there are still so many mosquitoes after spraying. That night Somchai writes in his notebook: "If this happens again next month, we will not respond the way we did today." That note is where the 100-day plan below begins.
This is an illustrative scenario written to explain the problem, yet many local leaders will recognize it. The issue is not that people do not care. The issue is that the subdistrict had no system in place before the emergency began.
Aedes mosquitoes carry dengue, chikungunya and Zika. Anopheles mosquitoes carry malaria in some areas. Dengue typically starts with a sudden high fever, headache and muscle pain, sometimes with small spots of bleeding under the skin. The most dangerous period is often when the fever starts to fall, because some patients can go into shock. The groups a leader must think about first are school children, older people, people with chronic illness and pregnant women, who face additional concern from Zika.
A local government does not treat disease. Its job is to reduce the number of mosquito vectors and cut the chance of further transmission. A mosquito sprayer kills adult mosquitoes that may carry the virus, while removing breeding sites breaks the cycle in the longer term. The two must always go together.
New mayors often find government assets bought years ago that still carry an asset number but no longer work. Buying a new machine in a hurry, without checking after-sales service, spare parts and training, risks turning the new machine into another idle one. The money spent never becomes results.
Residents do not remember which equipment the council bought this year. They remember very clearly whether the council came quickly when their children fell sick, and whether it came with an explanation or came silently and disappeared. In the first 100 days, these impressions stay with a leader for years.
Complaints no longer arrive only as official letters. They come through village LINE groups, the subdistrict Facebook page and private messages to the mayor. Without a standard reply and evidence that the team has been in the field, a small issue can become a large one within a single day.
A small council's public health and environment division may have only a handful of staff covering waste, wastewater, stray dogs, markets and communicable disease. If the mosquito fogger is heavy, hard to start or breaks often, staff become exhausted and demoralized. A good system reduces workload rather than adding to it.
This table is designed for a mayor to forward to the chief administrator and the head of the public health division. Each phase has a goal, main tasks and the evidence that proves the work was done. Timing can be adjusted to the size of the subdistrict and the season.
| Phase | Goal | Main tasks | Evidence |
|---|---|---|---|
| Days 1-10: know the real status | Understand readiness | Test every mosquito fogger, check chemical stock and protective equipment, list operators, collect past case data from the health promoting hospital | Equipment status table, one-page report |
| Days 11-30: assign people and command | Know who does what when a case appears | Appoint a task team, coordinate with health staff and village health volunteers, map risk points, set up a complaint channel | Appointment order, risk map, command chart |
| Days 31-60: tools and budget | Ready equipment and funding | Repair or dispose of old units, request quotations and specifications, arrange a demonstration, plan procurement by the rules | Demonstration report, draft specification, budget plan |
| Days 61-100: test and report | System runs without waiting for orders | Rehearse the first-case response, train operators, run a breeding site campaign, report to the council and residents | Drill record, photos, 100-day report |
The first instruction should be "survey everything we already have," not "buy a new machine now." Ask the supply officer and public health division to check every sprayer with an asset number: start it, spray plain water, and record which units work, which can be repaired and which should be written off. Check chemical stock for expiry and make sure there are enough masks, gloves and goggles.
At the same time, request past dengue case information from the local health promoting hospital or district health office. Precise figures are not needed. Knowing which villages see cases most often and which months are the peak is enough to plan when to be ready.
A good system answers simple questions at once. If the health centre reports a case at 4 p.m., who receives the call, who decides to spray, who sprays, who informs residents and who photographs the work? Issue an appointment order for a task team with a primary and a backup person for every role, because during an outbreak someone is always on leave, sick or busy elsewhere.
Work with village health volunteers to map risk points such as homes with many water containers, temples, schools, markets, scrap dealers and public ponds. This map becomes the base for targeted spraying and for records that can be reviewed later.
Once you know your equipment and your area, decide whether to repair, add or replace. For most subdistricts the core task is spraying around patients' homes within a radius of about 100 metres, usually in narrow lanes with houses close together and gardens behind them. A lightweight, durable handheld thermal fogger is therefore the tool that must always be ready. Subdistricts with long main roads or large open areas can later add a vehicle-mounted sprayer.
During this phase, ask suppliers to demonstrate in your own area. Let the staff who will actually use the machine hold it, start it and spray with it, and ask about spare parts, repairs and training. Then use this information to draft the specification and plan procurement according to regulations.
A system that has never been rehearsed does not really exist yet. Run a mock "first case reported" exercise: receiving the report, a loudspeaker announcement, spraying around the home, larval surveys and reporting in the executive LINE group. Note which steps got stuck. Close the 100 days with a short report to the council and residents on what has been done, what is pending and what next year's plan is.
Thermal fogger in one line: a machine that uses heat to turn insecticide into a visible fog that drifts into gaps, bushes and under houses so droplets reach mosquitoes.
ULV in one line: Ultra Low Volume, spraying a small amount of liquid broken into very fine droplets without heat; this is what a ULV cold fogger does.
Micron in one line: one thousandth of a millimetre, the unit used to describe droplet size.
The AIROFOG AT35 is a thermal fogger with a 100% stainless steel body. It is lightweight, works with both water-based and oil-based chemicals, and is certified in Germany and the UK. It is designed for homes, factories, hospitals and public areas, which matches a subdistrict council that sprays in many different settings each year.
| Feature (as stated by the supplier) | What it means for the council |
|---|---|
| 100% stainless steel body | Resists chemicals and moisture, reducing corrosion; suits an asset expected to serve for years |
| Lightweight | Staff can carry it longer through narrow lanes and around patients' homes |
| Water-based and oil-based chemicals | Flexible choice of formulation according to the area and health authority advice |
| Certified in Germany and the UK | Documentation to support procurement decisions and audits |
| Homes, factories, hospitals, public areas | One machine covers homes, schools, temples, markets and government buildings |
Beyond the machine itself, World Health Disinfection Co., Ltd. (WHD) holds ISO and GMP certification, performs 100% quality control before delivery, provides full after-sales service with technicians and spare parts, and its products meet Thai government equipment standards. Those are the guarantees that a machine bought in the first 100 days will still be ready in the third and fourth year of the term.
Good indicators use data the subdistrict already has. Choose from the examples below and set targets together with the local health centre.
| Indicator | How to collect | Owner |
|---|---|---|
| Share of sprayers ready to use | Monthly test run | Public health division and supply |
| Time from case report to spraying | Log report time and dispatch time | Task team lead |
| Households surveyed for larvae | Volunteer survey forms | Health centre and volunteers |
| Mosquito complaints answered on time | Complaint log or online form | Public relations |
| Operators trained | Training attendance list | Public health division |
Avoid a target of "zero cases." Case numbers depend on many factors a council cannot fully control. Measure what the team can influence, such as speed, coverage and readiness, and read case trends alongside them.
(A composite example based on typical field work, not a testimonial from a real person.)
"When the new mayor arrived, the first thing he asked for was a table showing where each machine was and whether it worked. At first the team wondered why he did not just order new ones. After the survey we found one unit we could repair and one we should write off. Once we had a lighter thermal fogger, several of us could take turns instead of waiting for the one colleague strong enough to carry the old machine. Most important, after we rehearsed the plan, everyone knew what to do when a real case came in. Nobody waited for a meeting."
Public health officer, subdistrict council (fictional persona)
Should a new mayor buy a mosquito fogger immediately?
Survey existing equipment first to see what can be repaired, then decide. This protects the budget and gives a clear justification for procurement.
Which machine should a small subdistrict start with?
Most need at least one ready handheld thermal fogger for work around patients' homes, such as the AIROFOG AT35, then other sprayers as the area requires.
Why does dengue continue after spraying?
Spraying reduces adult mosquitoes for a short time. If breeding sites remain, new mosquitoes emerge. Combine spraying with the "3 keeps" campaign: keep homes tidy, keep rubbish managed, keep water covered.
Is 100 days enough?
It is enough to build the core structure: status, people, tools and one test of the system. Improvement continues through the term.
Which budget line should be used?
A sprayer is an equipment item and belongs in the equipment line of the annual budget ordinance. Campaigns and training may use other channels according to their criteria. Consult the chief administrator and supply officer.
What if the machine breaks?
WHD provides after-sales service with technicians and spare parts. Call 065-556-6294 or LINE @whd268, and follow the maintenance steps in the manual after every use.
Which agencies should we work with?
Mainly the health promoting hospital, district health office, village health volunteers, community leaders, schools and temples. Follow the Department of Disease Control and local health authorities for technical guidance.
