Is dengue fever a real risk in Sri Lanka right now, and should tourists worry?

Travelers who arrived in Unawatuna in late August report seeing almost no mosquitoes despite staying near the jungle — it appears to be off-season for mosquitoes there.
Unawatuna — few mosquitoes, off-season
Dengue outbreaks in Sri Lanka are routine, similar to seasonal flu elsewhere. Coastal areas have very few mosquitoes. Using repellent is usually sufficient protection.
Western coast / Colombo — higher risk area
Dengue symptoms resemble food poisoning: diarrhea, vomiting, fever. Most tourists recover without seeing a doctor. A blood test is the only way to confirm the diagnosis.
There is no vaccine or specific treatment for dengue — only symptom management. Critically: only use paracetamol to reduce fever. Ibuprofen, aspirin, and similar drugs thin the blood, which is dangerous in severe dengue cases.
Paracetamol only — NOT ibuprofen/aspirin
Dengue has an incubation period of up to 10 days and is only transmitted by mosquito bites — not person to person. Mosquito repellents and plug-in fumigators are available in shops at Colombo airport on arrival.
