With the increase in dengue cases in Central America and the Caribbean and the start of the summer season in the Southern Hemisphere, the Pan American Health Organization / World Health Organization (PAHO/WHO) recently announced South American countries should prepare for dengue outbreaks.
As of September 2023, the PAHO/WHO assessed the risk of dengue outbreaks as high at the regional level due to the widespread distribution of the Aedes spp. mosquitoes.
Dengue Outbreaks in 2023 Include South Florida
Cholera Outbreaks Continue Without Ample Vaccine Supply
As September 2023 comes to a close, twenty-four countries are currently reporting active outbreaks. New data show over 472,000 cholera cases were reported in 2022, an increase of 47% in one year.
While cholera is a vaccine-preventable, severe disease, there is a global shortage of oral cholera vaccines (OCV), which, according to reports, may continue for years.
