A surge in cases of a mosquito-borne disease in South America has triggered an “emergency situation,” cautions a health official. There are concerns that this outbreak could soon spread to North America.
Summary of Events
According to a report by CNN, the Pan American Health Organization disclosed that by mid-April, there had been 5.2 million reported cases of dengue, surpassing the previous annual record established in 2023.
Director of PAHO, Jarbas Barbosa, highlighted the severity of the situation. While South America has borne the brunt of the infections, the upcoming change in seasons and warmer weather pose an escalating risk for North America.
Ashley Baldwin, a PAHO spokesperson, stated, “Most cases in the southern hemisphere occur in the first half of the year, and most cases in the northern hemisphere occur in the second half of the year. So far, this year, we have seen cases peak in the south, and we would now expect an increase in cases in the north.”
As of mid-April, Brazil declared a state of emergency due to a surge in dengue cases, while Peru issued a health alert for 20 out of its 25 regions.
The reported 1,858 deaths from dengue by mid-April are approaching the total of 2,418 reported in 2023.
Significance of the Situation
With global temperatures on the rise due to human-induced pollution, the conditions for mosquito breeding are becoming more favorable earlier and for longer periods.
Apart from dengue, other mosquito-borne diseases such as Zika, yellow fever, and chikungunya are also causes for concern.
Hospitals in Peru are being overwhelmed by dengue cases, with CNN reporting that over 2,000 patients had been treated for the illness in 2024, compared to 900 admissions in the entirety of 2023.
Preventive Measures against Dengue
Barbosa mentioned the availability of a dengue vaccine. While it may not immediately halt outbreaks, it can help diminish health complications and fatalities.
PAHO advocates for a surveillance strategy to monitor the disease’s spread, alongside controlling the mosquito vector responsible for virus transmission and enhancing healthcare services’ ability to manage the increasing cases.
Baldwin noted that most dengue cases are mild, and early detection can reduce the likelihood of the disease progressing to severe forms.
Additionally, reducing global temperatures can curb the ability of mosquitoes to breed. The insects lay their eggs in warm water, and if the conditions allow for prolonged breeding cycles, their presence will persist throughout the year.
Minimizing daily pollution is crucial. While individual efforts may seem limited, collective actions can have a significant impact.
For instance, supporting pro-climate candidates through voting can aid in implementing laws and policies to reduce the emission of greenhouse gases.
Taking local initiatives can inspire community-driven changes like promoting better public transportation options, enhancing recycling initiatives, and initiating community solar projects — which can also help local residents save on energy costs.
