Malaria still poses a real threat to travellers, particularly in areas with high transmission rates such as sub-Saharan Africa, Papua New Guinea, and the South Pacific islands. Malaria causes an estimated 660,000 deaths each year from 219 million cases of illness. It is a preventable and curable disease. Malaria symptoms appear after a period of seven days or longer, and without treatment, the disease can lead to death. Mosquito bite prevention is the main way to reduce malaria transmission. Chemoprophylaxis recommendations depend on travelers' age, destination, type of travelling, or length of stay. Pregnant women, children, and immunosuppressed travelers are the most susceptible. There are currently no licensed vaccines against malaria. Results about a research vaccine candidate known as RTS,S/AS01 are expected in 2015.

The activity of the paediatric service increased during the epidemic period. Consequently, implementation of surveillance activities and prevention and control programs for rotavirus in hospitals would seem advisable.

The results of a correlative study between computed tomography (CT) and transaxial histopathologic sections from cancerous larynges are presented. CT has proved highly reliable in accurately delineating the extent of tumor, but there remain problems of which the interpreter must be aware. This paper is designed to illustrate application of CT examination to the problem of cancer of the larynx.
