Dengue fever incidence; Trinidad and Tobago Dengue fever incidence; Trinidad and Tobago
Shows the increase in dengue fever as temperature rises in correlation with El Niño in Trinidad and Tobago. There is neither good prophylactic nor cure for dengue fever, a disease spread by Aedes aegypti mosquitoes. There are four different strains of the disease. Infection by one of the strains does not provide immunity against the other strains. The symptoms range from a non-specific viral syndrome to fatal hemorrhagic disease. Increasing tem...

Potential dengue transmission in case of temperature rise Potential dengue transmission in case of temperature rise
A warmer climate increases occasions of vector borne tropical diseases. This figure depicts weeks of potential dengue transmission under current temperature and 2°C and 4 °C warming. Presence of dengue virus, mosquito vector, and exposed human populations are required for disease transmission.

Africa: Stockholm convention on persistent organic pollutants (POPs) Africa: Stockholm convention on persistent organic pollutants (POPs)
The process initiated by UNEP in 1995, materialised as the Stockholm convention in May 2001. The convention bans chemicals such as chlordane, DDT and PCB and other organic pesticides and industrial chemicals, as well as establishing precautionary approaches for the future. Most African countries are using agents, such as DDT, for control of disease vectors and pests under exemptions.

Waste collection in Curitiba Waste collection in Curitiba
In the 1980s severe hygienic problems plagued parts of Curitiba where housing development was uncontrolled. The winding streets were too narrow for council trucks and waste rotting in the open caused disease. In 1989 the council decided to act. It sent environmental education teams into affected areas where they joined forces with neighbourhood associations to organise waste collection by local people.

Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species) Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species)
The comb jelly (Mnemiopsis leidyi) is well adapted to the habitat (salinity, temperature, and food range) and reproduces faster than endemic species. As it eats the same food as them, it has had a drastic effect on their numbers, upsetting the entire food chain. The jelly is an invasive species, brought from North America by ships.

Health in Central Asia, mortality, infant mortality, infectious diseases and cancer Health in Central Asia, mortality, infant mortality, infectious diseases and cancer
Health issues are of particular note in Central Asia with a high incidence of environmental pollution, and economies in transition. This graphic shows the relative numbers of mortality, infant mortality, deaths by infectious diseases and parasites, together with the rate of cancer mortality in Central Asia for the year of 1999.

Poverty and cholera in Kwazulu-Natal January 2001 Poverty and cholera in Kwazulu-Natal January 2001
Data and maps on poverty, sanitation, safe and clean water and the incidence of cholera were used to help contain the spread of cholera in the Kwazulu Natal province in January 2001. Poverty and cholera data sets showed that the cholera outbreak followed a river flood plain and moved through and towards poor areas.
