Oct 2, 2023 · Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. While many dengue infections are asymptomatic or produce only mild illness, the virus can occasionally cause more severe cases, and even death. Prevention and control of dengue depend on vector control.

Oct 2, 2024 · Dengue is a vector-borne disease transmitted by the bite of an infected mosquito. There are 4 serotypes of the virus that cause dengue. These are known as DEN-1, DEN-2, DEN-3 and DEN-4. Most dengue infections are mild and may not get noticed. Severe dengue is a potentially lethal complication which can develop from dengue infections.

May 30, 2024 · Dengue is a mosquito-borne viral disease caused by the dengue virus, with the potential to cause a serious public health impact. Dengue infections are the most common vector-borne viral infections worldwide, particularly impacting tropical and subtropical countries. DENV has the potential to cause epidemics resulting in high morbidity and ...

Oct 3, 2024 · Dengue is a mosquito-borne viral infection that is common in warm, tropical climates. Infection is caused by any one of four closely related dengue viruses (called serotypes) and these can lead to a wide spectrum of symptoms, including some which are extremely mild (unnoticeable) to those that may require medical intervention and hospitalization.

Jun 2, 2022 · What is dengue fever and severe dengue? Dengue is a vector-borne disease transmitted by the bite of an infected mosquito. There are 4 serotypes of the virus that causes dengue. These are known as DEN-1, DEN-2, DEN-3, DEN-4. Severe dengue is a potentially lethal complication which can develop from dengue infections.

Dec 21, 2023 · Dengue transmission is cyclic and large outbreaks every 3-4 years can be expected. During the COVID-19 pandemic we saw moderate transmission of dengue in some regions and low transmission in others leading to an accumulation of people without immunity to certain dengue virus serotypes. However, the data on the circulating dengue serotypes is ...

May 10, 2024 · TAK-003 is a live-attenuated vaccine containing weakened versions of dengue virus serotypes 1, 2, 3 and 4 developed by Takeda. TAK-003 uses the DENV2 strain as the genomic backbone. The vaccine schedule is a 2-dose series three months apart, given to specific age groups and in specific circumstances according to WHO recommendations.

Preventive and vector control interventions aim to reduce dengue transmission, thereby decreasing the incidence of the infection and preventing outbreaks of the disease. Unlike other mosquitoes, Aedes aegypti is a daytime feeder; its peak biting periods are early in the morning and before dusk in the evening.

Jul 22, 2024 · Dengue is a mosquito-borne viral disease caused by the dengue virus, with the potential to cause a serious public health impact. The primary vectors that transmit the disease are mosquitos of the Aedes genus, primarily Aedes …

May 15, 2024 · A new vaccine for dengue received prequalification from the World Health Organization (WHO) on 10 May 2024. TAK-003 is the second dengue vaccine to be prequalified by WHO. Developed by Takeda, it is a live-attenuated vaccine containing weakened versions of the four serotypes of the virus that cause dengue.
