Geographical gradient of mean age of dengue haemorrhagic fever patients in northern Thailand

Geographical gradient of mean age of dengue haemorrhagic fever patients in northern Thailand

Dengue haemorrhagic fever (DHF) is caused by dengue virus transmitted by Aedes mosquitoes; mean age of patients varies temporally and geographically. Variability in age of patients may be due to differences in transmission intensity or demographic structure. To compare these two hypotheses, the mean age of DHF patients from 90 districts in northern Thailand (1994-1996, 2002-2004) was regressed ...

Clinical profile and outcome of dengue fever and dengue haemorrhagic fever in pediatric age group

This study was conducted in the CICU and PICU of SCB medical college, Cuttack, Odisha, India. Patients with serologically confirmed dengue from 1 yr age to 16 years were included in this study. The period of study was from June 2014 to May 2015. 100 patients were included in this study. Patients were enrolled after obtaining written consent from parents. Patients with enteric fever, Rickettsial...

Dengue haemorrhagic fever

Factors increasing the risk of DHF outbreaks The occurrence of DHF outbreaks is linked to a number of factors, including the density of mosquito vectors, particularly that of Aedes aegypti. The precise population density of Ae. aegypti that is needed to sustain dengue virus transmission epidemically or endemically has yet to be determined, but experience in Singapore in recent years suggests th...

Dengue haemorrhagic fever

The two basic methods for establishing a laboratory diagnosis of dengue infection are detection of the virus (e.g. culture) or detection of anti-dengue antibodies (serology). Until recently, detection of the virus implied solely the recovery of the virus by culture; however, current procedures can detect dengue virus RNA and specific dengue virus antigens. Consequently, these procedures are lik...
