Overview

The 2026 Andes virus outbreak highlights the role of ophthalmologists in monitoring ocular manifestations associated with hantavirus infections. The CDC has issued a Health Alert Network advisory calling for heightened clinical vigilance due to confirmed cases linked to the outbreak.

Background

Emerging infectious diseases pose challenges to public health, necessitating a multidisciplinary approach to surveillance and response. The current Andes virus outbreak underscores the need for ophthalmologists to understand and characterize the ocular involvement associated with this pathogen.

Data Highlights

Ocular manifestations of hantavirus infections, particularly from Puumala virus, have been documented, but similar data for Andes virus are lacking.

Key Findings

The Andes virus outbreak in 2026 has prompted a call for ophthalmologists to participate in outbreak surveillance.
Ocular symptoms in Puumala virus include transient myopia, decreased intraocular pressure, and conjunctival chemosis.
The CDC has issued advisories for heightened clinical vigilance in response to the outbreak.
Andes virus is the only hantavirus confirmed to have person-to-person transmission.

Clinical Implications

Ophthalmologists should be aware of the potential ocular manifestations associated with hantavirus infections, particularly in the context of the Andes virus outbreak.

Conclusion

The involvement of ophthalmologists in monitoring ocular manifestations during the Andes virus outbreak is crucial for effective disease surveillance.
