Brazil is considering calling on Cuba to send doctors and has mobilized its military to join the nation's public health workers in battling a deadly outbreak of the mosquito-borne viral illness, dengue fever, which has killed 67 people and infected more than 45,000.

For the past few years, Rio De Janeiro, Brazil has been at the center of a resurgence of the disease in South America.

Earlier this week the state called on other Brazilian states to send pediatricians to help victims of the disease. Symptoms include high fever, joint pain and headaches, and although the mosquito-born virus usually isn't fatal, there have been at least 67 deaths in this epidemic so far according to reports.

More than 1,200 military troops are now spraying insecticides to get rid of mosquitoes. They have also erected hospital tents to treat those who are sick. But citizens are criticizing the government for not doing more sooner, the Washington Post Foreign Service reported Thursday.

U.S. Centers for Disease Control and Prevention have reportedly said that more people living in urban areas has contributed to the problem, because mosquitoes breed in tiny amounts of standing water and the increase in trash, coupled with infrequent trash collection and inadequate water and sewer services has increased the breeding places for mosquitoes.
