Solveig Jore's doctoral research shows that the tick Ixodes ricinus has spread over larger geographical areas in Norway and that climate and environmental changes, access to host animals and demography affect tick distribution in Norway. Furthermore, local climatic conditions can have a decisive influence on the ability of the tick to spread dangerous viruses. The climate can also play a role in the spread of gastrointestinal infections. http://medicalxpress.com/news/2013-04-climate-environmental-affect-occurrence-diseases.html Diseases, Conditions, Syndromes Mon, 15 Apr 2013 08:12:13 EST news285232326 Wageningen University in the Netherlands has developed a prototype vaccine against chikungunya in a joint effort with the Erasmus Medical Centre and TI Pharma.

Using this approach, a group from the UMR_D 190, Emerging viruses Department in Marseille, France in collaboration with the University of Sydney, Australia, demonstrated that the engineered viruses exhibit a stable phenotype with a significantly decreased viral fitness (i.e., replication capacity), making it a new vaccine candidate for this emerging viral disease.

It is caused by the Chikungunya virus (CHIKV), which is transmitted by mosquitoes and causes symptoms including fever, rash and joint pain. It can be incapacitating, with some patients developing severe chronic symptoms, and it is sometimes fatal. The main current control measure is to prevent exposure to mosquitoes; a vaccine would reduce the threat of CHIKV. http://medicalxpress.com/news/2012-07-exploiting-early-immune-response-chikungunya.html Immunology Wed, 04 Jul 2012 09:25:49 EST news260612742 Research funded by the Dengue Vaccine Initiative (DVI) involving an economic analysis of producing a tetravalent dengue vaccine shows that the cost could be as low as $0.20 per dose with an annual production level of 60 million doses packaged in ten-dose vials.
