Dengue has become a major public health problem in Sri Lanka with a considerable economic burden.

Increasing evidence from epidemiological studies suggests that maternal exposure to ambient PM2·5 can increase the risk of pregnancy loss. However, no studies have been done in low-income countries such as those in Africa, which have the highest incidences of pregnancy loss.

The objectives of this study were to characterize the emissions of indoor air pollutants from the burning of mosquito coils and cigarettes using a closed environmental chamber, to compare air pollutant emissions from different types of mosquito coils and cigarettes, which are popular in Indian market; to quantify emissions from burning of mosquito coils and cigarettes with respect to particulate matter (PM0.25, PM1.0, PM2.5, and PM10) and metals.

Voluntary, permanent land protection is a key conservation process in many coun-tries. Concerns with the effectiveness of such decentralized processes exist due tothe potential for (1) selection bias, that is, the protection of parcels whose land coverwould have been conserved in the absence of protection, and (2) local spill

The hypothesized link between the measles, mumps, rubella (MMR) vaccine and autism continues to cause concern and challenge vaccine uptake. The objective of the study was to evaluate whether the MMR vaccine increases the risk for autism in children, subgroups of children, or time periods after vaccination.

In order to overcome limitations of climate projections from Global Climate Models (GCMs), such as coarse spatial resolution and biases, in this study, the Statistical Down-Scaling Model (SDSM) is used to downscale daily precipitation and maximum and minimum temperature (T-max and T-min) required by impact assessment models.

The sex ratio at birth (SRB; ratio of male to female live births) imbalance in parts of the world over the past few decades is a direct consequence of sex-selective abortion, driven by the coexistence of son preference, readily available technology of prenatal sex determination, and fertility decline. Estimation of the degree of SRB imbal

During austral summer (DJF) 2017/18, the New Zealand region experienced an unprecedented coupled ocean-atmosphere heatwave, covering an area of 4 million km2. Regional average air temperature anomalies over land were +2.2 °C, and sea surface temperature anomalies reached +3.7 °C in the eastern Tasman Sea.

Farmers in the North West Himalayan region generally practise rainfed agriculture and have very limited scope for irrigation. Water scarcity is a major constraint for crop production in these areas. This problem exacerbates further during the Rabi season where vagaries of winter rain result in complete crop failure.

Social network data of tuberculosis (TB) patients could explain the source and pattern of disease spread. A review of the published literature highlights that social network data could identify hidden social or epidemiological links among TB patients and improved TB case finding.
