Dengue despair!

Spraying insect repellent

In Brazil, Rio de Janeiro health officials are on alert, with dengue cases having risen by almost half this year compared with the same period in 2018, and a campaign has been launched to reduce the infestation of mosquito-borne diseases.

“We need action uniting the population and governments working together, working in the mosquito presence foci, which is the only effective way to prevent these diseases,” said Rafael Pinheiro, Co-ordinator in Environmental Health Surveillance of the Municipal Health Secretariat of Rio. There have been more than 1,000 reported cases, many of which have been in Santa Cruz and Campo Grande.

In Araraquara, São Paulo, 50 new dengue cases are being recorded each day and 18 cities in the north west have been warned that epidemics may be imminent, while in the Dominican Republic, rates of dengue fever and malaria have risen substantially.

In order to avoid infection, travellers can implement measures to help protect themselves such as covering up with long-sleeved tops and trousers when mosquitoes are most active and applying repellent.
