“…40 It is intriguing that other studies did not find an association with sex; cultural determinants in these communities could explain this finding. 37,[41][42][43] In regard to occupation, when adjusting by age, locality, and sex, independent workers, senior citizens without salary, disabled individuals, retirees, and housewives were associated with a higher seroprevalence compared with students. In addition, the relationship between seroprevalence and housewife status has previously been reported in Singapore, and these observations may have two explanations.…”

Abstract. Humoral immune response against dengue virus (DENV) is an important component in dengue-endemic transmission. We conducted a cross-sectional nested cohort study to determine the seroprevalence and frequency of neutralizing antibodies against DENV serotypes in two endemic localities in the state of Morelos, Mexico. The cohort participants (N = 1,196) were screened to determine previous exposure to DENV. Overall seroprevalence was 76.6% (95% confidence interval [95% CI] = 73.6-79.2), and prevalence of neutralizing antibodies in the 5-to 9-year-old group was 82.5% (95% CI = 67.2-92.7), 45% (95% CI = 29.3-61.5), and 65% (95% CI = 48.3-79.4) for DENV-1, DENV-2, and DENV-3, respectively. For participants older than 10 years, the observed seroprevalence was above 60% for each serotype, except DENV-4 in the 10-to 25-year-old group (42.9%); 81% of humoral responses were multitypic. The outcomes of our study contribute to understanding the immune component of dengue transmission and provide focal information for the evaluation of vaccine candidates under development.

“…• Local determinants Dengue should not be considered a poverty-related disease because it affects wealthy neighbourhoods as well, although the magnitude of risk can be moderated by the use of housing materials such as screens in doors and windows 27,28 . In Taiwan, it was estimated that 63% of dengue infections could be eliminated if everyone lived in adequately screened homes 29 .…”

Dengue is the most important vector-borne disease in the Americas and threatens the lifes of millions of people in developing countries. Imprecise IntroductionDengue is now the most important vector-borne disease in the Americas and threatens the health of millions of people that live in urban, suburban and rural environments. Clinical and public health services have been unable to diminish this disease since there is no vaccine available to prevent infection, no effective medical treatments that avert the development of severe symptoms and no sustainable control measures against the vector that guarantee protection of affected communities.Dengue was initially identified as breakbone fever in 1790 in Philadelphia, U.S.A 1 , and later spread throughout the Americas, until the Pan American Health Organization (PAHO) launched an Aedes aegypti eradication campaign to combat yellow fever in the 1950s and 1960s that came close to eliminating the vector from the continent 2 . Although the geographical distribution of the vector is similar to its distribution before the eradication campaigns 3 , populations during the "eradication era" were principally rural. In the last 40 years, there has been intensive urbanization due to massive migration from agricultural areas to cities. Although urbanization in Latin America and the Caribbean had already reached 41% of the population by 1950, the population living in urban areas is expected to reach between 82 and 84% by 2030; by then the Latin America and Caribbean region will be the second most urbanized REVISÃO REVIEW Gómez-Dantés H, Willoquet JR S20 Cad.

Females has are at a higher risk compared to males was found by another study in Thailand by the same researchers [17].…”

Abstract-Dengue outbreak occurs in Indonesia, including Medan. We selected socio-demographic profile of the community, its behavior and environment in order to see dengue dynamic within the same location. Medan Baru represents the highest reported case, and Medan Area, for the lowest reported case. A total of 840 respondents, calculated by WHO's rapid survey (2 x 210 from each sub-district). Respondents were the head of household (male or female) and have been living in the area for a minimum of two consecutive years. Questionnaires were distributed to assess the demographic profiles, knowledge, attitude and practice. Environment assessment made to measure environmental risk. We found that Medan Area carryinga higher risk of dengue.The majority of respondents was adults, women, those living in permanent homes and whose educational background was up tosecondary high school or less.Most respondents lived in their own house and spent most of their time in the morning outside the home to work. Respondents' knowledge of and attitude towards dengue were relatively good.Generally, the respondents participated in some efforts to prevent dengue. Many mosquito'slarvae were still present in more than 1 container. After deployed binary logistic regression atα=0,05, the risk factors of dengue in Medan Area were higher to those who performed activities at home in the morning with poor quality of hygiene both inside and outside home.This research concluded that people were highly exposed to the risk of dengue when they failed to maintain and manage a healthy living environment maximally.
