Dendroctonus rufipennis

Dendroctonus rufipennis, the spruce beetle, is a native North American bark beetle killing mature spruce across the continent. Distinguished from Ips typographus and D. ponderosae by its spruce hosts, two-year life cycle, and major Alaska and Yukon outbreaks.

Dendrocygna

Dendrocygna, the whistling-ducks or tree ducks (genus Swainson 1837), eight tropical Anseriformes species with whistled calls, long legs, and debated family rank as Dendrocygnidae versus subfamily Dendrocygninae of Anatidae.

Dendrohyrax

Dendrohyrax (tree hyraxes, tree dassies) is a genus of 3–5 kg nocturnal, arboreal afrotherian mammals in Procaviidae, order Hyracoidea, related to elephants; species include D. arboreus, D. dorsalis, D. validus, and the 2022-described D. interfluvialis.

Dendrolycopodium

Dendrolycopodium (tree-clubmoss) is a clubmoss genus in Lycopodiaceae, subfamily Lycopodioideae, established by A. Haines in 2003 from Lycopodium; five species including D. obscurum, x=34, stalked terminal strobili.

Dendrolycopodium obscurum

Dendrolycopodium obscurum, flat-branched tree-clubmoss or princess-pine, is a North American clubmoss described by Linnaeus in 1753 as Lycopodium obscurum; tree-like shoots, underground stems, homosporous cones, and confirmed hybridization with D. dendroideum.

Dendronephthya

Dendronephthya (carnation coral) is a genus of about 250 species of non-photosynthetic Nephtheidae soft corals of the Indo-Pacific, feeding on plankton in strong currents, notoriously difficult to identify to species without DNA markers.

Dendrophylax lindenii

DengiAll

DengiAll (DengiALL) is Panacea Biotec's single-dose tetravalent live attenuated dengue vaccine, derived from NIH TV003/TV005 strains, in Phase III trials with ICMR across 19 Indian sites since August 2024, enrolling 10,335 adults.

Dengue

Dengue is a mosquito-borne viral disease transmitted by the day-biting mosquitoes Aedes aegypti and Aedes albopictus, causing around 5 million cases and over 5,000 deaths worldwide in 2023.

Dengue fever

Dengue fever, also called dengue and severe dengue, is a mosquito-borne flaviviral disease (DENV-1 to DENV-4) spread by Aedes aegypti; ~390 million infections yearly, severe plasma leakage on secondary infection, treated by fluid therapy, vaccines Dengvaxia and Qdenga.

Dengue fever outbreaks

Dengue fever outbreaks: epidemic surges of the four-serotype dengue virus transmitted by Aedes aegypti and Aedes albopictus. Four historical phases in the Americas; 2024 set the record with over 14 million reported cases worldwide.

Dengue tetravalent vaccine, live

Dengue tetravalent vaccine, live is Dengvaxia (CYD-TDV), Sanofi's live attenuated chimeric yellow fever 17D-based dengue vaccine, first licensed in 2015, indicated only for seropositive people, and discontinued in 2024–2026 for low demand.

Dengue vaccine

Dengue vaccines protect against the four dengue virus serotypes. Dengvaxia (CYD-TDV, Sanofi) was first licensed in 2015 but restricted to seropositive recipients and later discontinued; Qdenga (TAK-003, Takeda) was WHO prequalified in 2024 for children 6-16 in high-transmission settings.

Dengue virus

Dengue virus (DENV), a mosquito-borne flavivirus with four serotypes (DENV-1 to DENV-4), spread by Aedes aegypti and Aedes albopictus; causes dengue fever, with severe risk in secondary infections via antibody-dependent enhancement; vaccines include Qdenga (TAK-003).

Dengue Virus Infection

Dengue virus infection (dengue, break-bone fever): mosquito-borne Flaviviridae infection with four serotypes, spread by Aedes aegypti; 100–400 million infections yearly, no specific antiviral treatment, Qdenga vaccine prequalified 2024.

Dengue with warning signs

Dengue with warning signs, a tier of the WHO 2009 dengue classification, marks symptomatic dengue patients showing indicators such as persistent vomiting, mucosal bleeding, or liver enlargement, requiring hospital management.

Dengue without warning signs

Dengue without warning signs (ICD-11 1D20) is the mildest WHO 2009 dengue category: fever with non-specific symptoms, no alarm signs, managed as an outpatient, though severe dengue can still develop.
