“…23 Like Malaysia, dengue is also endemic in Brunei Darussalam, and the main mosquito vectors can also be detected locally. 26,27 Hence, it is likely that such prevention practices have already been established at the community level for preventing mosquito-borne diseases other than Zika virus infections.…”

A cross-sectional survey was conducted to assess the knowledge and practices on Zika virus infection among general adults in Brunei Darussalam. From February to June 2017, 439 adults were interviewed from outpatient health care settings. Most participants were Malays (87.0%) and females (61.5%), with a mean age of 40.7 years. Only 25.1% had a total knowledge score of 15 to 28 points (of a possible score of 0-28). Females and those living in households of <8 people were more likely to have higher total knowledge scores (15-28 points). Media was the preferred source to get updates. Also, 67.4% had a total prevention practice score of 19 to 36 points (of a possible score of 0-36). Those who attained secondary level education or below, had no pregnant women present in their household, and scored 15 to 28 points for knowledge were more likely to have higher prevention practice scores (19-36 points). Knowledge on Zika was significantly associated with prevention practices against mosquito bites and breeding.

“…The laboratory determined LC 50 for the development of fi rst instar Ae. albopictus larvae to adults in Brunei Darussalam in brackish water was approximately 9 ppt salinity (Idris et al 2013 ). Aedes aegypti was however found in brackish water in a house from a water village on the Brunei river estuary (Ramasamy and Surendran 2013 ).…”

Mosquito vector-borne diseases are a signifi cant health problem in South and Southeast Asia. Some mosquito vectors in the region are well known to lay eggs and undergo pre-imaginal development in brackish water. However, a number of other important vectors, e.g. Anopheles culicifacies (malaria) and Aedes aegypti and Aedes albopictus (dengue and chikungunya), have previously been widely held to do so exclusively in freshwater. But recent evidence shows that these species can also lay eggs and undergo pre-imaginal development in brackish water collections in coastal areas of the region. This property produces a reservoir of vectors that are not targeted in larval control programmes. It can contribute to disease transmission in a previously unrecognised manner that can be compounded by environmental changes caused by expanding populations in coastal zones, climate change and rising sea levels due to global warming. Increased disease transmission in coastal areas will also lead to higher disease incidence in inland areas. Many countries in South and Southeast Asia have long coastlines, a high proportion of coastal zone relative to total land area and a large proportion of the population living in coastal areas. Hence, the region is particularly vulnerable to disease transmission by brackish water vectors. Appropriate policies and strategies need to be developed in a local, national and international context to counter this threat to human health in South and Southeast Asia.

“…The two Aedes vectors are able to develop in brackish water microhabitats of up to 15 ppt (parts per thousand or gL −1 ) salt in beach litter, and up to 9 ppt salt in domestic wells and surface drains in coastal areas of the Jaffna peninsula [14][15][16][17][18][19]. Salinity-tolerant Aedes vectors have since been detected in other countries [20][21][22][23], with worldwide implications for the epidemiology and control of arboviral diseases [24][25][26]. The greater salinity tolerance of Ae.…”

Regional Variation in Dengue Virus Serotypes in Sri Lanka and Its Clinical and Epidemiological Relevance

Dengue is a significant health concern in Sri Lanka, but diagnosis of the infecting dengue virus (DENV) serotype has hitherto been largely restricted to the Colombo district in the western province. Salinity tolerant Aedes vectors are present in the island’s northern Jaffna peninsula, which is undergoing rapid groundwater salinization. Virus serotypes were determined by RT-qPCR in 107 and 112 patients diagnosed by NS1 antigen positivity from the Jaffna district in 2018 and 2019, respectively, and related to clinical characteristics. DENV1 and DENV2 were the most common serotypes in both years. Infections with multiple serotypes were not detected. DENV1 was significantly more prevalent in 2019 than 2018, while DENV3 was significantly more prevalent in 2018 than 2019 among the Jaffna patients. Limited genomic sequencing identified DENV1 genotype-I and DENV3 genotype-I in Jaffna patients in 2018. Dengue was more prevalent in working age persons and males among the serotyped Jaffna patients. DENV1 and DENV2 were the predominant serotypes in 2019 in the Colombo district. However, DENV1 and DENV3 were significantly more prevalent in Colombo compared with Jaffna in 2019. The differences in the prevalence of DENV1 and DENV3 between the Jaffna and Colombo districts in 2019 have implications for dengue epidemiology and vaccination. Salinity-tolerant Aedes vector strains, widespread in the Jaffna peninsula, may have contributed to differences in serotype prevalence compared with the Colombo district in 2019. Significant associations were not identified between virus serotypes and clinical characteristics among Jaffna patients.
