Rabies in Argentina: A Five-Year Review and Future Outlook
Argentina has been monitoring rabies cases in both animals and humans over the past five years (2021-2026). Whereas human cases remain rare, the ongoing presence of animal rabies, particularly in bats and cattle, necessitates continued vigilance and public health efforts.
Human Rabies Cases: A Rare but Serious Threat
Between 2021 and early 2026, Argentina investigated 10 suspected cases of human rabies. Of these, only one was confirmed, occurring in 2021 in Coronel Suárez, Buenos Aires province. This case, unfortunately, was fatal. The confirmed case was attributed to antigenic variant 4, carried by the Tadarida brasiliensis bat species. As of early 2026 (through Epidemiological Week 9), no suspected or confirmed human cases have been reported this year.
The majority of investigated human cases with negative results were located in the Autonomous City of Buenos Aires (three cases), Buenos Aires province (five cases), and Santa Fe province (one case). This geographic distribution highlights areas requiring focused surveillance.
Animal Rabies: A More Common Occurrence
The data reveals a more significant presence of animal rabies. A total of 803 confirmed animal rabies cases were reported between 2021 and 2025. 2022 saw the highest number of cases (224), while 2024 reported the lowest (127). The national trend demonstrates fluctuating numbers, with a median of 135 cases annually.
Species at Risk: Bats and Cattle
Insectivorous bats are the primary reservoir for rabies in Argentina, with the highest number of detections in the Autonomous City of Buenos Aires (45 cases), Buenos Aires province (366 cases), La Pampa (83 cases), Santa Fe (32 cases), and Córdoba (29 cases). Cattle are also affected, particularly by paralytic rabies transmitted by hematophagous bats (Desmodus rotundus), with cases concentrated in Chaco (59) and Formosa (36).
Companion animals are also susceptible. Seven cases were reported in dogs (Formosa – five, Buenos Aires – one, Chaco – one) and six in cats (Buenos Aires – five, Córdoba – one) during the same period.
The Role of Bat Transmission: A Recent Case Study
Recent research has highlighted the potential for rabies transmission from bats to other animals, and subsequently to humans. A 2021 case documented the first instance of human rabies originating from an insectivorous bat (Tadarida brasiliensis) transmitted through a feral cat in Buenos Aires province.
Public Health Considerations and Prevention
The CDC recommends that all international travelers be fully vaccinated against measles. While not directly related to rabies, this underscores the importance of preventative healthcare measures when traveling internationally.
Pro Tip: If you are bitten or scratched by an animal while in Argentina, wash the wound thoroughly with soap and water and seek immediate medical attention. Post-exposure prophylaxis is highly effective in preventing rabies if administered promptly.
FAQ
Q: How common is rabies in Argentina?
A: Human rabies is rare, with only one confirmed case between 2021 and 2026. However, animal rabies is more prevalent, with hundreds of cases reported annually.
Q: Which animals are most likely to carry rabies in Argentina?
A: Insectivorous bats are the primary reservoir, followed by cattle and, to a lesser extent, dogs and cats.
Q: What should I do if I am bitten by an animal in Argentina?
A: Wash the wound thoroughly with soap and water and seek immediate medical attention.
Q: Is there a risk of rabies from bats even if they don’t bite?
A: While direct bites are the most common transmission route, contact with bat saliva or nervous tissue can also pose a risk. Avoid handling bats, even if they appear dead.
