Recent clusters of outbreaks of mosquito-borne diseases (Rift Valley fever and chikungunya) in Africa and parts of the Indian Ocean islands illustrate how interannual climate variability influences the changing risk patterns of disease outbreaks. Although Rift Valley fever outbreaks have been known to follow periods of above-normal rainfall, the timing of the outbreak events has largely been unknown. Similarly, there is inadequate knowledge on climate drivers of chikungunya outbreaks.

Corporation cites environmental, topographical reasons

Cases of dengue-chikungunya co-infection are on the rise, causing concern to health planners and doctors. About three per cent of dengue-chikungunya cases fall under the co-infection category, with the patient suffering from both the diseases at the same time.

Developed for troops serving on glaciers high in the Himalayas, the non-flushing “bio-digester” toilet made by India’s top defence research body is now being offered to companies and poorer states. It is one of 200 technologies produced by the Defence Research and Development Organisation (DRDO) identified as for-sale via the Federation of Indian Chambers of Commerce and Industry (FICCI).

As the world continues to pump greenhouse gases into the atmosphere, the global temperatures could rise by 3°C by mid-century, says a soon-to-be-released report of the Intergovernmental Panel on Climate Change. Extreme weather events will become even more intense. Erratic monsoons and severe cyclones have already battered large parts of India this century. Should we still blame the increasing disasters on unpreparedness of governments and bad planning? Down To Earth investigates

Aedes aegypti (Linnaeus) and Aedes albopictus Skuse mosquitoes transmit serious human arboviral diseases including yellow fever, dengue and chikungunya in many tropical and sub-tropical countries. Females of the two species have adapted to undergo preimaginal development in natural or artificial collections of freshwater near human habitations and feed on human blood. While there is an effective vaccine against yellow fever, the control of dengue and chikungunya is mainly dependent on reducing freshwater preimaginal development habitats of the two vectors. We show here that Ae.

Thirty people have been primarily detected with Chikungunya fever in Shibganj upazila of the district while many others received treatment with similar symptoms here during the last one month. Chikungunya, a viral disease marked by fever, headache, rash, nausea, pain in muscles and joints, is transmitted to humans through biting of Aedes mosquito, said doctors. The doctors of Shibganj upazila health complex recently provided treatment to some patients with symptoms of Chikungunya, locally called langra jar.
