Since 2014, the Federative Republic of Brazil has been confronting chikungunya virus outbreaks without being able to offer its massive population access to an effective and safe vaccine.
During 2024, Brazil's situation has intensified. 
As of September 2024, over 383,000 chikungunya cases and 165 related fatalities have been reported this year.

As summer approaches in the Southern Hemisphere and mosquito-transmitted diseases peak, the Argentine Republic has announced plans to defeat the ongoing dengue virus outbreak.
According to Argentina's Epidemiological Bulletin week #35, posted on September 9, 2024, 764,901 dengue cases and over 400 related deaths have been reported nationwide, with 56,435 cases in the Autonomous City of Buenos Aires this year. 

Since human papillomavirus (HPV) vaccines were first recommended in the United States in 2006, uptake rates increased for most of the years.
Recent data indicates that HPV vaccination rates have recently stalled around 62%, with some states reporting variable rates segmented by urban and rural counties.
According to an Original Investigation published by the JAMA Network Open, northern Texas's counties and health service regions (HSR) have a higher incidence of HPV-related cancers and lower HPV vaccination rates than elsewhere in the state. 

International travelers booking last-minute trips to disease-outbreak countries often wonder how quickly their vaccination will provide protection. A new study has shown that in just two weeks, Takeda Vaccines, Inc.'s second-generation dengue vaccine protects people from this mosquito-transmitted disease.
This finding is great news for many travelers, as the global dengue outbreak continues unabated in September 2024.

In the United States, most people say that polio has been eradicated for many years. While this assumption may be accurate for U.S. residents, international travelers should have a different perspective.
For the 139th time, the WHO Director-General convened the Emergency Committee under the International Health Regulations (2005) (IHR) on the international spread of poliovirus.

Public health officials announced that measles was officially eliminated from the United States in 2000 and is no longer an active health risk.
The U.S. Centers for Disease Control and Prevention (CDC) says this significant achievement demonstrated how effective vaccine policies can reduce contagious diseases. Most new cases in the U.S. can be traced to unvaccinated, infected individuals who brought the virus into the country.

In its newly published report, the World Health Organization (WHO) has revealed a significant increase in global cholera outbreaks.
The WHO stated on September 4, 2024, that the number of reported cholera cases has risen by 13%, and fatalities have increased by 71% in 2023 compared to 2022.
Unfortunately, over 4,000 individuals succumbed to this vaccine-preventable and 38% of the reported cases affected children under the age of five last year.
