An early warning system has been developed by scientists for alerting authorities of risk of dengue fever outbreaks during the World Cup in Brazil.
As per the analysis published in Lancet Infectious Diseases, it is estimated that there is a high chance of outbreaks of this mosquito-borne disease.
It is said that there are risks warranting an alert warning in three venues: Recife, Fortaleza and Natal. On June 29, England will play in Recife. There are millions of fans who will travel to the twelve different cities and that are hosting matches during the World Cup, running from the June 12 to July 13.
More cases of Dengue fever were recorded in Brazil than anywhere else in the world between in the years 2000-2013.
More on Dengue fever from Wikipedia:
Dengue fever, also known as breakbone fever, is a mosquito-borne tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
