Results show that urbanization is not necessarily associated with intense dengue transmission in Thailand, and paradoxically, the DHF incidence in Bangkok has surpassed other regions despite declines in transmission intensity.

Relationship between Transmission Intensity and Incidence of Dengue Hemorrhagic Fever in Thailand

The negative relationship between DHF incidence and dengue transmission intensity implies that in regions of intense transmission, insufficient reduction of vector abundance may increase long-termDHF incidence.

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

SUMMARY 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…

Genetic Diversity of Dengue Virus and Associated Clinical Severity During Periodic Epidemics in South East Asia

The chapter has been divided in three parts: the historical evolution of the dengue virus in the region its spatial and temporal distribution, the effects of covariates such as poverty, water supply, sanitation and global warming on expansion of thedengue endemic regions and an attempt has been made to relate the mutational changes of d Dengue genotypes with disease severity.

Dynamics of dengue transmission in the arid region of Sonora, Mexico

The association between 2006-2011 dengue incidence and social and climatic factors in localities of the state of Sonora, Mexico was assessed to assess whether localities reporting no cases might be associated with factors related to under-reporting.

Characterizing dengue transmission in rural areas: A systematic review

A systematic review to synthesize research on dengue in rural areas and summarize aspects of rurality used in current epidemiological studies of DENV transmission given changing and mixed environments found the force of infection appears to be increasing over time, as measured by increasing seroprevalence in children and thus likely decreasing age of first infection.

The 2012 Madeira Dengue Outbreak: Epidemiological Determinants and Future Epidemic Potential

It is proposed that there is little support for dengue endemicity on this island, but a high potential for future epidemic outbreaks when seeded between May and August—a period when detection of imported cases is crucial for Madeira's public health planning.

Impact of sars-cov-2 interventions on dengue transmission

Examination of pre and post differences of dengue case counts in Malaysia, Singapore and Thailand finds that social distancing is expected to lead to 4.32 additional cases per 100,000 individuals in Thailand per month, which equates to 170 more cases per month in the Bangkok province, while adjusting for temporal confounders.

Geographical association between socioeconomics and age of dengue haemorrhagic fever patients in Surabaya, Indonesia

Results suggested that socioeconomic factors which affect mosquito abundance are more important determinants of the mean age of DHF patients than the demographic variables, which are related to the prevalence of poor housing where mosquito density was high.

Modeling and prediction of dengue occurrences in Kolkata, India, based on climate factors

The regression model developed uses maximum temperature, minimum temperature, relative humidity and rainfall as key meteorological factors on the basis of statistically significant cross-correlation coefficient values to predict dengue cases and concludes that from December to February, RCP8.5 leads to suitable warmer weather conditions essential for the survival and multiplication of d Dengue pathogens.

Changing epidemiology of dengue hemorrhagic fever in Thailand

The age of highest incidence has increased, and the age group most severely affected is now those 5–9 years old, so the case fatality rate has decreased with improved treatment and is now only 0·28%.

Travelling waves in the occurrence of dengue haemorrhagic fever in Thailand

This work uses the method of empirical mode decomposition to show the existence of a spatial–temporal travelling wave in the incidence of DHF, and observes this wave in a three-year periodic component of variance, which is thought to reflect host–pathogen population dynamics.
