Since its inception, the national surveillance-training program applies the same WHO dengue classification system from 1968 [ 32], which classifies symptomatic dengue into dengue fever (DF) and DHF.
Experience with two other diseases spread by the same mosquitoes, dengue and chikungunya, offer insights as well.
Other viral diseases spread by the same mosquitoes including dengue and chikungunya that have caused massive epidemics south of the U.S. border have triggered only small outbreaks in the United States.
We also need to know if different tissues [ 164] within a single host house the same dominant dengue virus strain.
IgG titers for the same contrived dengue-positive samples that were dried in the blood tubes, were also stored for up to 28 days at ambient temperature or 37°C, and measured using a commercial ELISA at various time points.
A central piece of evidence for those who contend that India suffers hundreds of times more dengue cases than the government acknowledges is a recent and as yet unpublished study of dengue infections in West Bengal that found about the same presence of dengue as in Thailand, where almost every child is infected by dengue at least once before adulthood.
Shortly after their arrival at the second island, dengue was diagnosed in all 4. At the same time, a dengue epidemic was identified on the first island.
The finding that febrile patients, but not blood donors from Dhaka from the same period, had dengue antibodies suggests that many of the febrile illnesses we evaluated in 1996 were caused by dengue, 4 years before the epidemic dengue was documented.
This group includes suspected dengue cases collected during the same period as the dengue cases, but for which dengue infection was not confirmed through either RT-PCR/virus isolation or serology in at least three blood samples collected at different days.
Both carry the same viruses, including dengue, yellow fever and chikungunya.
