Health Ministry Deploys Emergency Teams
On July 4, senior officials from Cambodia's Ministry of Health visited Koh Thom District to assess the situation firsthand.
The delegation met with healthcare workers, hospital administrators, and local authorities to evaluate patient care, hospital readiness, and ongoing prevention efforts.
Officials also inspected healthcare facilities treating dengue patients and reviewed plans to strengthen disease surveillance across the district.

Additional cases have also been identified in surrounding communes throughout Koh Thom District.
Health officials continue monitoring nearby communities for signs of further transmission.
Mosquito Control Campaign Intensified
To reduce mosquito populations and prevent additional infections, authorities have expanded several public health measures, including:
Community-wide insecticide spraying
Distribution of mosquito larvicide (Abate)
Elimination of standing water where mosquitoes breed
Public awareness campaigns
School-based health education
Household inspections
Local governments are working alongside health workers to identify mosquito breeding sites and encourage residents to participate in prevention efforts.

Wearing protective clothing
Keeping homes and schools clean
Eliminating containers that collect rainwater

Understanding Dengue Fever
Dengue fever is a mosquito-borne viral illness transmitted primarily by Aedes mosquitoes, which often bite during daylight hours.
Common symptoms include:
High fever
Severe headache
Pain behind the eyes
Muscle and joint pain
Skin rash
Nausea and vomiting
Severe dengue can cause dangerous bleeding, shock, and organ complications if medical treatment is delayed.
Anyone experiencing persistent high fever or warning signs should seek medical care immediately.
Public Urged to Stay Vigilant
Health authorities are encouraging residents to take preventive action by:
Removing standing water around homes
Covering water storage containers
Using mosquito repellent
Installing window screens or sleeping under mosquito nets where appropriate
Seeking medical attention promptly if symptoms develop
Officials stress that community cooperation remains one of the most effective ways to control dengue outbreaks.
Final Thoughts
The recent surge of dengue fever cases in Koh Thom District highlights the importance of rapid public health intervention during mosquito season. While no fatalities have been reported, the large number of infections demonstrates how quickly dengue can spread when mosquito populations increase.
Cambodia's Ministry of Health continues working with local authorities to contain the outbreak through medical care, mosquito control, and public education. Residents are encouraged to remain alert and follow prevention guidelines to help reduce the risk of further transmission.
