Germany's national disease control center says a further 94 people have been sickened by the deadliest E-coli outbreak in modern history. The Robert Koch Institute (RKI) said the number of registered infections in Germany rose to 2,325 on Tuesday 7 June 2011, with those in other European countries still standing at about 100.
The institute adds the latest figures indicate that the number of new cases is declining, a sign that the epidemic might have reached its peak. But it cautions that it is not certain whether the latest decrease will continue in the coming days. It said the number of people suffering from a serious complication that may lead to kidney failure among those sickened rose by 12 to 642.

Dengue fever is spread by daytime biting mosquitoes normally from sunrise to sunset and is more common in urban areas. It causes a high ‘breakbone’ fever (pain all over), accompanied with a headache and a rash. It lasts a few days and will resolve itself. If caught a second time it has a 2% chance of developing into Dengue Haemorrhagic fever which can be fatal. There is currently no vaccine available and therefore insect bite avoidance is essential.
