In February, during the early stages of the coronavirus pandemic, two patients in Singapore initially recorded false-positive test results for dengue and were thus misdiagnosed before later being found to actually have COVID-19; this included one patient who was originally reported as the first to have been infected with both diseases.
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]
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.
Cells infected with Epstein–Barr virus, one of the viruses implicated in PAISs. Pathogens associated with PAISs include SARS-CoV-2 (causing COVID-19), Ebolavirus, Dengue virus, poliovirus, SARS-CoV-1 (causing SARS), Chikungunya virus, Epstein–Barr virus (EBV), West Nile virus (WNV), Ross River virus (RRV), Coxsackie B, influenza A virus subtype H1N1, varicella zoster virus (VZV), Coxiella ...
The most widely known ADE example occurs with dengue virus. [34] Dengue is a single-stranded positive-polarity RNA virus of the family Flaviviridae. It causes disease of varying severity in humans, from dengue fever (DF), which is usually self-limited, to dengue hemorrhagic fever and dengue shock syndrome, either of which may be life ...
Epidemic dengue has become more common since the 1980s. By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year. Significant outbreaks of dengue fever tend to occur every five or ...
Dengue virus has four different serotypes, each of which are antigenically related but have limited cross-immunity to reinfection. [55] Although dengue fever has a global incidence of 50–100 million cases, only several hundreds of thousands of these cases are life-threatening.
The 2019–2020 dengue fever epidemic was an epidemic of the infectious disease dengue fever in several countries of Southeast Asia, including the Philippines, Malaysia, Vietnam, and Bangladesh, [1] Pakistan, [2] India, Thailand, Singapore, and Laos. [3]
