In Indonesia it costs about US$207 for the recommended three doses.Given the limitations of the current vaccine, research on vaccines continues, and the fifth serotype may be factored in. One of the concerns is that a vaccine could increase the risk of severe disease through antibody-dependent enhancement (ADE). The ideal vaccine is safe, effective after one or two injections, covers all serotypes, does not contribute to ADE, is easily transported and stored, and is both affordable and cost-effective. Anti-dengue day
International Anti-Dengue Day is observed every year on 15 June. The idea was first agreed upon in 2010 with the first event held in Jakarta, Indonesia, in 2011. Further events were held in 2012 in Yangon, Myanmar, and in 2013 in Vietnam. Goals are to increase public awareness about dengue, mobilize resources for its prevention and control and, to demonstrate the Southeast Asian regions commitment in tackling the disease. Management
There are no specific antiviral drugs for dengue; however, maintaining proper fluid balance is important. Treatment depends on the symptoms. Those who can drink, are passing urine, have no "warning signs" and are otherwise healthy can be managed at home with daily follow-up and oral rehydration therapy. Those who have other health problems, have "warning signs", or cannot manage regular follow-up should be cared for in hospital. In those with severe dengue care should be provided in an area where there is access to an intensive care unit.Intravenous hydration, if required, is typically only needed for one or two days.
Both IgG and IgM provide protective immunity to the infecting serotype of the virus. In testing for IgG and IgM antibodies there may be cross-reactivity with other flaviviruses which may result in a false positive after recent infections or vaccinations with yellow fever virus or Japanese encephalitis. The detection of IgG alone is not considered diagnostic unless blood samples are collected 14 days apart and a greater than fourfold increase in levels of specific IgG is detected. In a person with symptoms, the detection of IgM is considered diagnostic. Prevention
Prevention depends on control of and protection from the bites of the mosquito that transmits it. The World Health Organization recommends an Integrated Vector Control program consisting of five elements:
Advocacy, social mobilization and legislation to ensure that public health bodies and communities are strengthened;
Collaboration between the health and other sectors (public and private);
An integrated approach to disease control to maximize the use of resources;
Evidence-based decision making to ensure any interventions are targeted appropriately; and
Capacity-building to ensure an adequate response to the local situation.The primary method of controlling A. aegypti is by eliminating its habitats. This is done by getting rid of open sources of water, or if this is not possible, by adding insecticides or biological control agents to these areas. Generalized spraying with organophosphate or pyrethroid insecticides, while sometimes done, is not thought to be effective. Reducing open collections of water through environmental modification is the preferred method of control, given the concerns of negative health effects from insecticides and greater logistical difficulties with control agents.
