doi: 10.1371/journal.pntd.0008541. Monthly data on dengue cases and mosquito larval indices were ascertained between 2004 and 2008 in the Dak Lak province (Vietnam). Most infested containers were water storage vessels, such as old metal Among them, the house index (HI), and the Breteau index (BI) are the most widely used (32, 33). This study suggests that communities affected by dengue can benefit from investments in vector control if interventions are implemented rigorously and coordinated well across sectors. However, the effectiveness of monitoring Aedes albopictus using the MOT and other mosquito monitoring methods, such as the Ovitrap (OT) and the CO2-light trap (CLT), have not been extensively compared.

The increasing frequency and intensity of dengue outbreaks in endemic and non-endemic countries requires a rational, evidence based response. Mosquito-borne diseases, such as dengue fever and Zika, have posed a serious threat to human health around the world. Curve fitting of logistic model and TARs data at different levels of rHBR. In the base-case scenario of moderate level of hospitalisation, the CIMIC programme was cost-saving with a probability of 70% under both the lowest ($453) and highest ($1686) cost-effectiveness thresholds, resulting in a net saving of $20 247 (95% CI −57 266 to 97 790) and averting 176 DALYs (133 to 226), leading to a cost of −$98 (−497 to 395) per DALY averted. In comparison, for control cases, the Breteau index averaged (5.4 ± 1.83) and, while still high, was significantly lower than that for DHF cases in 84 of 87 cases (P < 0.0001, sign test). Our main contributions are to: (1) uncover underlying topics from news articles that discuss dengue in Asian countries in 2014; (2) construct topic evolution graphs through the year; and (3) analyze the life cycle of dengue news articles in India, then relate them to rainfall, monthly reported dengue cases, and the Breteau Index. translated into Breteau, container, and house indices (estab-lished indicators of mosquito density) (5). Controlling vector mosquitoes is an effective method to prevent these diseases. 2021 Jan 6;14(1):22. doi: 10.1186/s13071-020-04463-x. From 11 August to 8 September, 2018, a dengue outbreak was reported with 27 confirmed cases in a population of 5536-people community (community A) of Ningbo City. Urban and rural differences and the variations during pre-monsoon and monsoon seasons were also studied. Accompanying CD-ROM contains graphic footage of various war wound surgeries.

Apart from that, four of them were found to be positive for both dengue IgM and NS1 antigen in their blood samples. The third edition of this, one of Springer’s renowned and authoritative Major Reference Works, contributes to these goals in several ways. First, the number of entries has been increased by about 30%. Vector surveillance was implemented during the outbreak to collect the larva and adult mosquito densities to calculate the Breteau Index (BI) and human biting rate (HBR), respectively. An Information value based analysis of physical and climate factors affecting dengue fever and dengue haemorrhagic fever incidence. The Breteau index was >10 for 75% of the DHF cases indicating a high degree of vector activity .

Prevention and treatment information (HHS). Conclusion: Following the investigation, a detailed report was made, which was shared with the district health authority. A transmission mathematical model was developed to dynamic the incidence of the disease. Among these indices, BI which is defined as the number of positive containers (i.e. Monthly Breteau index showed a higher value (range 35.4-13.8) between July and October, where most of the suspected and dengue positive cases were reported (Fig. Fig 7.
