Vangvieng setting for Health Ministry, WHO-produced dengue prevention film

Since the start of the rainy season in July of this year, the numbers of cases of dengue has been increasing significantly in several provinces including Vientiane, Champassak, Savannakhet, Saravan, Khammuan and Borikhamxay and the capital..

In the popular tourist destination of Vangvieng, Vientiane province, efforts are being made by the local authorities to stop dengue transmission byproviding dengue prevention messages and vector control clean-up activities,in partnership with local communities.These activities include creating a short film on dengue prevention and transmission to communicate the message more effectively.

Dengue fever patients at the Vangvieng district hospital usually feel better after 1-2 days.

The film has been produced by the Centre of Information and Education for Health, World Health Organisation in collaboration with Vangvieng district Health Office and Vangvieng district hospital.

The film has been created to advise about dengue prevention and transmission and the precautions to take to protect themselves and concludes on a clear overview of dengue symptoms.

The film features the Head of the Vangvieng Health Office and Hospital, Dr Phatsamone, joined by villagers in Phonsou, where the number of dengue cases has beenon the rise in recent months.

The film focusses on the community mobilisation activity that the villagers are given on dengue,learning it is important to clear their homes and surrounding areas of mosquito breeding sites, at least once a week.

In addition, Phonsou village head, Mr Luangdala is shown leading the community clean-up activities by picking up discarded rubbish along the road, something that is becoming part of daily life for local people.

The film also has an important scene featuring Dr Chanthapanya, a Medical Doctor at the Vangvieng district Hospital, the local representative from Lao Women's Union, and some people suffering from Dengue as they seek medical help at the hospital.

In this scene, Dr Chanthapanya explains about dengue symptoms and prevention.

Dengue should be suspected when a high fever (40°C) is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands or rash. Symptoms usually last for 27 days after an incubation period of 410 days after the bite from an infected mosquito.

Severe dengue is a potentially deadly complication due to plasma leaking, fluid accumulation, respiratory distress, severe bleeding, or organ impairment. Warning signs occur 37 days after the first symptoms in conjunction with a decrease in temperature (below 38°C) and include: severe abdominal pain, persistent vomiting, and rapid breathing, bleeding gums, fatigue, restlessness and blood in vomit. The next 2448 hours of the critical stage can be lethal; proper medical care is needed to avoid complications and risk of death.

For severe dengue, medical care by physicians and nurses experienced with the effects and progression of the disease can save lives decreasing mortality rates from more than 20 percent to less than 1 percent. Maintenance of the patient's body fluid volume is critical to severe dengue care.

The main method to control or prevent the transmission of dengue virus is to combat vector mosquitoes through:

preventing mosquitoes from accessing egg-laying habitats by environmental management and modification;

disposing of solid waste properly and removing artificial man-made habitats;

covering, emptying and cleaning of domestic water storage containers on a weekly basis;

applying appropriate insecticides to water storage outdoor containers;

using of personal household protection such as window screens, long-sleeved clothes, insecticide treated materials, coils and vaporizers;

improving community participation and mobilisation for sustained vector control;

applying insecticides as space spraying during outbreaks as one of the emergency vector-control measures;

Active monitoring and surveillance of vectors should be carried out to determine effectiveness of control interventions.
