Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear they typically begin 3 to 14 days after infection.
Dengue vaccine is a vaccine used to prevent dengue fever in humans. [9] Development of dengue vaccines began in the 1920s, but was hindered by the need to create immunity against all four dengue serotypes. [10] As of 2023, there are two commercially available vaccines, sold under the brand names Dengvaxia and Qdenga. [11] [12]
President Benigno Aquino III at the launching of the dengue vaccine school-based immunization program. In April 2016, the DOH launched the dengue vaccination campaign in Central Luzon, Calabarzon and Metro Manila, where about 700,000 individuals received at least one dose of the vaccine. [11] The government paid P3.5-billion for the vaccine. [10]
Insect repellents help prevent and control the outbreak of insect-borne (and other arthropod-bourne) diseases such as malaria, Lyme disease, dengue fever, bubonic plague, river blindness, and West Nile fever. Pest animals commonly serving as vectors for disease include insects such as flea, fly, and mosquito; and ticks (arachnids). [citation ...
Patients in the early phase of the dengue virus may recover without hospitalization. However, ongoing clinical research is in the works to find specific anti-dengue drugs. [50] Dengue fever occurs via Aedes aegypti mosquito (it acts as a vector).
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
The process of climate change has produced abundant rains and high temperatures, (a phenomenon called tropicalization) favouring the reproduction of the mosquito that transmits the dengue virus, advancing the epidemic this year by several weeks compared to previous seasons, which historically, Infection peaks tended to occur between March and April, suggesting a continued increase in cases.

In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs. [2] Dengue is spread by several species of mosquito of the Aedes type, principally A ...
