Lassa fever: why there are more public health questions than answers

The Lassa virus can wipe out entire families. It is transmitted by rats and is endemic to west Africa – so why is there no vaccine? Lina Moses shares her experiences of working in Sierra LeoneI'm in a village in eastern Sierra Leone staring at a row of dead rats snared in branches, leaves and grass. The contraptions are called funnel traps, or tolei in the local Mende dialect. We're hoping these devices and other easily accessible or producible materials will lower the rodent populations in villages sufficiently to prevent Lassa fever.With a DfID-funded project called Wash (water, sanitation health), Facility Sierra Leone, Tulane University and Kenema Government Hospital are working in 20 villages introducing Lassa fever education and rodent control training. For the project to be successful, we have to control one of the most ubiquitous rodents in sub-Saharan Africa, Mastomys natalensis — the multimammate rat.Lassa fever is common in this part of the country where the disease can wipe out entire households and cause panic throughout villages. The disease has a gradual onset of fever, aches and pains that are indistinguishable from malaria or typhoid — diseases as familiar to villagers as the common cold. For some, Lassa fever will progress from these non-specific symptoms to sore throat, facial oedema, haemorrhaging and death. Although Lassa fever and its severe consequences are well-known by residents in this region, fewer know the rat that commonly infest...

Authors: Ferella A, Aguirreburualde MSP, Sammarruco A, Parreño V, Santos MJD, Mozgovoj M Abstract Bovine respiratory syncytial virus (BRSV) is one of the most relevant agents responsible for respiratory disease in cattle from both dairy and beef farms. BRSV is spread by horizontal contact causing a constant presence of seropositive animals that favors viral circulation throughout the year. Moreover, reinfections with BRSV are frequent between animals regardless of their age as BRSV does not confer long-lasting protective immunity. Several studies have demonstrated the circulation of BRSV in cattle from diffe...

CONCLUSIONS: Immunization Information System is an essential technological innovation for the management of immunization actions. However, the production of timely records and the use of information are still challenges. Investments in training are required to ensure System's management and operationalization activities.

Authors: Kyrkoudis T, Tsoucalas G, Fiska A Abstract The choice of Dedeagatch as the place where the station of the Adrianoupolis-Constantinople railway line was to be built was the reason for the foundation of the Greek city of Alexandroupolis (originally under the Ottoman government). The population grew in its early years mainly due to the settlement by railway and construction workers. Meanwhile, poverty, poor hygiene and environmental conditions led to a series of epidemics and various sporadic cases of infections such as malaria, typhoid fever, scarlet fever and tubercolosis, infections which marked the early ...

Authors: Meregildo ED Abstract Neurocysticercosis (NCC) is a global health problem. In more developed countries, NCC is mainly a disease affecting immigrants. In developing countries, NCC is the most common parasitic disease of the nervous system and the main cause of acquired epilepsy. NCC is also an unrecognized cause of strokes and could account for 4%-12% of strokes. Here, I report a case of a 58-year-old woman who presented to the emergency department (ED) with severe headache, vomiting, and sudden loss of consciousness. Multiple NCC and Fisher grade 4 aneurysmal subarachnoid hemorrhage (SAH) were demonstrated...
