Hantavirus infections have drawn renewed attention following recent outbreak reports. Dr. Pastula explains that hantavirus is not a single disease but a family of viruses with distinct characteristics depending on geographic region and rodent host — and that mortality rates can approach 40% in the most severe form found in the Americas.

MedicalResearch.com: What roles do a decrease in US immunization rates and/or increased immigration from under-vaccinated area play in this increase?
Response: The substantial majority of unimmunized children in the US were born and raised in this country. They usually are members of middle- or upper-income families. The most frequent importers of measles into the US are our own unimmunized children who travel abroad, encounter measles virus and bring it back to their homes where the virus then spreads among the child’s schoolmates and playmates, creating an outbreak.

MedicalResearch.com: What is the background for this outbreak?
Response: India has reported 2 confirmed (PCR and ELISA) Nipah virus (NiV) cases in West Bengal State where the Kolkata megalopolis is located; the state borders Bangladesh. Symptom onset in both cases was late December 2025 in 2 health care workers. One patient has improved while the other remains in the ICU. All samples from 200 contact persons tested negative for NiV. No further confirmed cases have been detected in West Bengal
Bangladesh has reported 1 confirmed NiV case in Rajshahi Division which neighbors India. Symptom onset was January 21, 2026, and the patient expired on January 28. The patient reported no travel history but reported repeated consumption of raw date palm sap between 5 and 20 January.

MedicalResearch.com: What is the background for this study?
Response: Shingles (herpes zoster) is caused by reactivation of the varicella-zoster virus, which can inflame blood vessels and the nervous system. Evidence over the past decade has linked shingles to higher risks of heart attack, stroke, and dementia—but it was unclear whether the shingles vaccine might lessen those long-term effects.
