Peru is battling its worst dengue outbreak in recent years with almost 200 reported deaths and nearly 150,000 cases, and the El Niño weather phenomenon is being blamed.
More than 1,300 people are being hospitalized daily.
El Niño is a climate phenomenon that drives tropical cyclones in the Pacific and thus raises the risk of rainfall and flooding in countries in the region. A season of heavy rains can trigger a rapid expansion of mosquito populations because of the accumulation of water in various places.
Dengue Danger
According to the U.S. Centers for Disease Control and Prevention (CDC), about 1 in 4 people who get infected by the dengue virus will get sick. Among those who do get sick, symptoms can range from mild to severe.The most common symptoms of dengue are fever, along with some other discomforts, such as nausea, vomiting, rashes, aches, or pain in the muscles, joints, bones, or behind the eyes. There’s no specific medicine for treating dengue.
Roughly 1 in 20 people who get sick with dengue are expected to develop severe sickness that can result in shock, internal bleeding, and even death. Those who have already contracted dengue in the past are more likely to develop severe dengue.
Children are believed to be at particular risk from severe dengue.
Health Alert, Global Situation
On June 7, the U.S. Embassy in Lima issued a health alert warning about the spread of dengue fever in the South American nation and advised travelers to sign up for the Smart Traveler Enrollment Program to receive updates from the embassy.“Because dengue is spread by mosquito bites, all travelers to risk areas should prevent mosquito bites by using an EPA-registered insect repellent, wearing long-sleeved shirts and long pants when outdoors, and sleeping in an air-conditioned room or room with window screens or under an insecticide-treated bed net,” the agency stated.
According to the World Health Organization (WHO), about half of the world’s population is at risk of contracting dengue, with annual infections ranging from an estimated 100 million to 400 million.
Over the decades, the number of dengue cases reported to WHO has soared, jumping to 5.2 million in 2019 from 505,430 cases in 2000. Since a vast majority of cases are asymptomatic or mild and self-managed, the organization believes that the actual number of cases is underreported.
