Health Emergency Declared in Rio de Janeiro due to Spike in Dengue Cases

The authorities in the Brazilian city of Rio de Janeiro have declared a health emergency as they try to contain the spread of dengue fever. Dengue cases have quadrupled in Brazil in January compared to the same month last year, with Rio alone registering 10,000 cases so far this year. The disease, transmitted by mosquitos, can cause fever, severe headaches, muscle and joint pain, and a blotchy rash. In an effort to reduce the number of serious cases and deaths, Rio city hall has announced the opening of 10 treatment centers for people with dengue. Health officials have also urged individuals to take preventive measures in order to avoid mosquito bites, such as applying repellent and eliminating stagnant water where mosquitos breed. Fumigators are spraying the worst affected areas and public health announcements will be made at the Sambadrome, the venue for Rio’s famous Carnival parade.
