Dengue infection is caused by the dengue virus that belongs to the family Flaviviridae.
There are 4 serotypes (DENV-1, DENV-2, DENV-3, DENV-4). Each serotype provides specific lifetime protective immunity against reinfection of the same serotype, but only temporary (within 2-3 months of the primary infection) and partial protection against other serotypes.
It is transmitted to humans through the bites of infected Aedes mosquitoes. It is primarily transmitted by female Aedes aegypti, a tropical and subtropical species. Humans are the main host of the virus.
After 4-10 days of incubation period, illness begins immediately.
Most children treated with discordant antibiotics for third-generation cephalosporin-resistant urinary tract infections (UTIs) may experience initial clinical improvement, with only a few requiring escalation of care, according to a study. This highlights the aptness of using current narrow-spectrum empiric therapy regimens while awaiting final urine culture results.
