The International Water Management Institute (IWMI) was commissioned to undertake a rapid review of access to and management of water resources in the Dry Zone, to assist LIFT and other potential donors and investors to identify the key issues and the priority actions for water management.
The ... study had three main components:
• A water resources assessment (surface and ground water) of availability, current use, and patterns, trends and variability at different spatial and temporal scales.
• Community survey to evaluate issues of water availability, access and management for different livelihood types in 24 local communities, including evaluation of institutional arrangements in relation to farming strategies and water management practices
• Review and analysis of existing program investments in water in the Dry Zone
Findings from the study are available in three reports (for details, see last page). more

Coronavirus disease 2019 is also known as COVID-19. It is a viral illness that infects the lungs. It is caused by a virus called SARS-associated coronavirus (SARS-CoV-2). This illness was first seen in late 2019 in China and has spread across the world.
The signs of COVID-19 are like the flu, and y

ou may have a cough, fever, and it may be hard to breathe. It spreads easily through droplets with the virus when you sneeze or cough. The germs also survive on surfaces like tables, door handles, and telephones. That means you can become sick if you touch a surface with the virus and then touch your face.
Some people have a mild case of COVID-19 and are able to stay at home until they feel better. Others may need to be in the hospital if they are very sick. People with COVID-19 most often have to isolate themselves for about 2 weeks.

Current evidence indicates that the COVID-19 virus is transmitted through respiratory droplets or contact. Contact transmission occurs when contaminated hands touch the mucosa of the mouth, nose, or eyes; the virus can also be transferred from one surface
...
to another by contaminated hands, which facilitates indirect contact transmission. Consequently, hand hygiene is extremely important to prevent the spread of the COVID-19 virus. It also interrupts transmission of other viruses and bacteria causing common colds, flu and pneumonia, thus reducing the general burden of disease.

eas with high risk of exposure. The country is endemic to both Schistosoma mansoni and Schistosoma haematobium, these infections are common in communities characterised with limited access to water, sanitation, hygienic practices and health services. Schistosoma mansoni infection is associated with hepatosplenic disease characterised with hepatomegaly, splenomegaly, progressive periportal fibrosis (PPF) which can lead to portal hypertension and its related sequelae, mainly ascites, liver surface irregularities, oesophageal varices and haematemesis. The main consequences of S. haematobium infection are haematuria, dysuria, nutritional deficiencies, urinary bladder lesions, hydronephrosis, urinary bladder squamous cell carcinoma and in children, growth retardation. Preventive chemotherapy using mass drug administration (MDA) of praziquantel targeting primary school aged children is the main strategy for controlling schistosomiasis in Tanzania.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca

n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

de the treatment of minor injuries, childhood ailments, and complications of pregnancy. Plants described in the book are also used as emetics and as ointments and dressings applied to surface wounds or used to treat skin problems.
Addressed to ethnobotanists, phytochemists, and pharmacologists, the book aims to document traditional clinical uses and bring these to the attention of the international scientific community, while also preserving knowledge about the distinctive indigenous practices in these island communities. Full-colour photographs are included to facilitate identification of plants and plant parts used for medicinal purposes. Each plant is described according to a common format, which includes information on scientific name, local names, English name, a description of the plant and its habitat and distribution, and a summary of what is known about its chemical constituents, biological activity, and traditional uses.

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector.

ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.
