How climate change influences the spread of disease - four essential reads
Climate change has led to extreme weather events such as floods and drought. These events have become more frequent and more severe. Natural disasters associated with climate change have a devastating effect on people’s lives, destroying homes, roads and others key infrastructure. They also put of injury and death, and alter the prevalence and distribution of illnesses and infectious diseases.
Africa turns into a disease basket
Africa turns into a disease basket Climate change is likely to increase the spread and incidence of tropical diseases in Africa The African climate is a natural incubator of many tropical diseases, such as malaria, cholera, Rift Valley Fever (RVF), meningitis, yellow fever, dengue and chikungunya. These diseases are caused by pathogens that are temperature-sensitive. It is predicted that the frequency of these anomalous events will increase as the planet becomes warmer.
Kenya: Malaria Control Strategies Reduce the Caseload - but Bring New Challenges
analysis By Andrew Githeko, Kenya Medical Research Institute and Ednah OtotoKenya's two major malaria prevention strategies - indoor residual spraying of homes in high transmission areas and the issuing of insecticide treated nets - have led to a significant reduction in malaria transmission. The two methods were introduced in the country's western highlands, traditionally considered a high transmission area, about a decade ago and have resulted in the disease's caseload decreasing by about 80%.

The two methods were introduced in the country's western highlands, traditionally considered a high transmission area, about a decade ago and have resulted in the disease's caseload decreasing by about 80%. But the drop in cases has brought a new challenge: people have begun losing their immunity to the disease. The consequence is that they are prone to contracting more complicated forms of the malaria that could result in death.

Prompt response to malaria outbreak is critical as risk of disease spreads
The outbreak, which is worse than previously recorded in the area for this time of year, can be attributed to a number of factors. These include a dysfunctional health service: there aren't any qualified health workers to test for malaria and there is a shortage of drugs to treat the disease. The situation has been made worse by a four-month long strike by nurses in public hospitals.
Prompt response to malaria outbreak is critical as risk of disease spreads
A malaria outbreak has killed 26 people in Marsabit in northern Kenya over the past one month. Over 1,000 people have been treated for the disease. The outbreak, which is worse than previously recorded in the area for this time of year, can be attributed to a number of factors. These include a dysfunctional health service: there aren’t any qualified health workers to test for malaria and there is a shortage of drugs to treat the disease.
African academics set out what Dr Tedros needs in his toolbox to tackle health ills
Africa has the highest burden of HIV/Aids and malaria with escalating rates of non-communicable diseases. How will the World Health Organisation’s Director-General Dr Tedros Ghebreyesus deal with the mounting challenges? The Conversation Africa asked academics across the continent what impact his appointment will have, and for advice on what he needs to do, to manage the challenges. What is the significance of his appointment?
Kenya: How Kenya Can Manage Its Increasing Dengue Fever Cases
analysis By Andrew Githeko, Kenya Medical Research InstituteA public health alert for 150 dengue fever cases has been issued in Mombasa, Kenya. The Conversation Africa's Health and Medicine Editor Joy Wanja Muraya spoke to Dr Andrew Githeko on the effective management of this disease whose spread is encouraged by water storage trends. What causes dengue fever and what type of human behaviour favours its breeding?

Africa: Anti-Malaria Efforts Face a New Hurdle - Drug and Insecticide Resistance
interview By Andrew Githeko, Kenya Medical Research InstituteThe resistance of malaria parasites to antimalarial drugs and insecticides is a growing global public health concern. The Conversation Africa's Health and Medicine Editor Joy Wanja Muraya asked Dr Andrew Githeko to explain how African countries can maintain the effectiveness of existing malaria control strategies as they work towards its elimination. The problem of drug resistant malaria is growing in Africa.

East Africa: Response to Climate Change Is Critical As Risk of Disease Outbreaks Grows
analysis By Andrew Githeko, Kenya Medical Research InstituteClimate change threatens to significantly increase the health risk of people living in the East African Highlands. In addition, droughts have intensified. These have have both short-term and long term effects on human health. Yet there are no guidelines to inform health related decisions under climate change conditions.

Climate change threatens to significantly increase the health risk of people living in the East African Highlands. In addition, droughts have intensified. These have have both short-term and long term effects on human health. Yet there are no guidelines to inform health related decisions under climate change conditions. Nor has any mapping been carried out to indicate the extent of changes in the geographic range of climate sensitive diseases and climate change.
