A Danish-Tanzanian research group has discovered that the mosquito carrying the malaria parasite has practically disappeared from villages without organized mosquito control, and the researchers do not know why. There are several hypotheses but without proper data they cannot say whether malaria is being eradicated or whether it is just resting up before returning with renewed vigour. http://medicalxpress.com/news/2011-08-malaria-mosquito-good-news.html Diseases, Conditions, Syndromes Thu, 25 Aug 2011 12:55:24 EST news233495711
