The city of Piura in northern Peru is grappling with a record-breaking outbreak of dengue, a mosquito-borne virus. Lorena Vigo, a 43-year-old resident, experienced the debilitating symptoms of dengue firsthand, including bleeding gums, headache, upset stomach, and joint pain.
The overwhelmed healthcare system left her unable to use her public health insurance, forcing her to pay for her own medications and self-treat at home.
Peru has reported nearly 150,000 cases of dengue this year, with a death toll of 248, making it the most severe outbreak in Latin America. Dengue cases have been increasing globally, with reported cases surging from 505,430 in 2000 to 5.2 million in 2019, as stated by the World Health Organization.
The outbreak in Peru can be attributed to a combination of factors, including unusually warm and rainy conditions triggered by a tropical cyclone and a localized El Niño effect.
These conditions have facilitated the breeding of the Aedes aegypti mosquito, the primary vector for dengue, which thrives in standing water. Rising temperatures have allowed the mosquito to expand its range, replicate the dengue virus more efficiently, and increase its biting frequency.
Poverty and inadequate sanitation infrastructure have further exacerbated the outbreak, as many Peruvians lack running water and proper sewage systems, leading to the storage of water in containers that serve as breeding grounds for mosquitoes.
Criticism has been directed towards the Peruvian government for its response to the epidemic.
The lack of preparation and insufficient resources within the public healthcare system has contributed to the challenges in managing the outbreak.
Dr. Leslie Soto, an infectious diseases expert, emphasized the need to improve primary care and rebuild public trust following the high mortality rate from COVID-19. The resignation of Rosa Gutiérrez, the former health minister, further highlighted the government's shortcomings in handling the outbreak.
Efforts to address the situation have included fumigation campaigns and public awareness campaigns urging residents to use mosquito nets and eliminate potential breeding sites.
While scientists are cautious about directly linking the outbreak to climate change, the combination of this year's weather events and Peru's unusual climate conditions have created an environment conducive to the proliferation of dengue-carrying mosquitoes.
The occurrence of dengue in previously unaffected regions, including countries like Canada, Croatia, and France, suggests that the disease is spreading beyond traditional boundaries. As global warming continues, the current dengue outbreak serves as a warning of the increasing frequency and impact of such outbreaks worldwide.
