background: epidemics of mosquito-borne viral infections such as dengue, chikungunya, west nile and rift valley fevers in neighbouring countries and risk of introduction of exotic vectors into iran have placed this country at a significant risk for these mosquito-borne diseases. methods: after the first dengue case reported in iran in 2008, active entomological surveillance of aedes albopictus ...

BACKGROUND A dengue early warning system aims to prevent a dengue outbreak by providing an accurate prediction of a rise in dengue cases and sufficient time to allow timely decisions and preventive measures to be taken by local authorities. This study seeks to identify the optimal lead time for warning of dengue cases in Singapore given the duration required by a local authority to curb an outb...

A large epidemic of dengue in Townsville and Charters Towers, north Queensland, Australia, initiated the development of a Dengue Fever Management Plan for north Queensland (DFMP) in 1994. The DFMP integrated disease surveillance, vector control and health promotion activities to prevent dengue outbreaks. While initially successful in preventing the recurrence of epidemic dengue in north Queensl...

Zika virus co-circulates with dengue in tropical and sub-tropical regions. Cases of co-infection by dengue and Zika have been reported, the implication of this co-infection for an integrated intervention program for controlling both dengue and Zika must be addressed urgently. Here, we formulate a mathematical model to describe the transmission dynamics of co-infection of dengue and Zika with pa...

To look for risk factors for dengue and community participation in dengue control in Binh Thuan Province, Vietnam, three communes with a low incidence of dengue and three with a high incidence, in Binh Thuan Province, were compared. Knowledge, perception and preventive practice of dengue were measured by means of a structured questionnaire. A check list of environmental observations was used to...

BACKGROUND Reported as a public health problem since the 1960s in Sri Lanka, dengue has become a high priority disease for public health authorities. The Ministry of Health is responsible for controlling dengue and other disease outbreaks and associated health care. The involvement of large numbers of public health staff in dengue control activities year-round and the provision of free medical ...

Dengue is one of the vector borne viral disease prevalent worldwide. During the last half a century, the incidence of dengue has increased by 30-fold and expanded to many new countries, and also from urban areas to rural areas (WHO 2009). It is estimated approximately 294 million in apparent dengue infections and about 96 million apparent dengue infections occurred worldwide in 2010, and Asia h...

Dengue is a major issue in Malaysia as the dramatic emerge of infection. Yet an effective vaccine or medicine is not yet available, although many attempts are undergoing. Dengue vector control is still considered the most effective way for controlling and preventing the transmission of dengue virus. Nonetheless, as the conventional approaches are less successful in managing the dengue transmiss...
