Dengue Haemorrhagic Fever with Bradycardia

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...

Relative bradycardia in dengue fever.

To the Editor—I read with interest the article by Chuang et al.1 The authors do not mention bradycardia as an important finding in dengue fever. Heart rate, as well as body temperature, is routinely recorded in all febrile patients. Lateef et al2 report that relative bradycardia (pulse temperature deficit) should raise awareness of such an infection. While this feature may be noted in other inf...

Dengue & Dengue Haemorrhagic Fever in Bangladesh

Dengue (pronounced as 'Dhen Gey') is a mosquito borne febrile viral illness. Since its first recognition during the last quarter of eighteenth century, periodic outbreak has been reported from both developed and developing countries with Asia always remaining the area of highest endemicity Until the middle of 20th century dengue was regarded as self-limited, non-fatal febrile illness with occas...
