Public health officials in California have issued an urgent alert after a rabid bat in Fremont tested positive for the rabies virus, triggering a targeted community response in the city’s Glenmoor neighborhood. The discovery has prompted Alameda County Vector Control to initiate door-to-door notifications to ensure residents are aware of the risk and the necessary precautions for their families and pets.
The incident began on Tuesday, March 31, 2026, when a dead bat was discovered at a residence on Logan Drive. Fremont Police Department records indicate that Alameda County Vector Control responded to the scene to collect the animal for professional testing. The following day, April 1, 2026, the Alameda County Department of Public Health confirmed that the bat was positive for the rabies virus.
As a physician and health journalist, I must emphasize that while these reports can be alarming, the current situation is being managed with a high degree of caution. According to county health officials, We find currently no known human or animal exposures associated with this specific incident, and no other similar cases have been reported in the vicinity per reports from KTVU.
Emergency Response in the Glenmoor Neighborhood
The primary objective of the current response is prevention. Because rabies is a fatal disease that affects the brain and nervous system, the window for effective intervention is narrow. To mitigate risk, Alameda County Vector Control is serving as the lead agency, conducting direct outreach to residents in the area where the bat was found to ensure no accidental exposures went unnoticed.
Health officials are urging the public to remain vigilant. The rabies virus is transmitted through saliva, typically via bites or scratches. The critical takeaway for the community is that rabies is entirely preventable, provided the affected person or animal receives a series of vaccination shots as soon as possible after the exposure occurred.
Guidance for Pet Owners
Domestic animals, particularly those not fully vaccinated, are at risk. Health officials have issued specific directives for pet owners in the Fremont area to prevent potential transmission:
- Strict Confinement: Keep all pets confined to your property to prevent them from encountering wild bats.
- High-Risk Animals: Puppies under three months vintage are particularly vulnerable and should be kept indoors and away from potential wildlife contact.
- Immediate Reporting: If a pet has had any contact with a bat in the Glenmoor area, owners are instructed to contact their veterinarian immediately and notify Fremont Animal Services at (510) 790-6635 as reported by county officials.
Medical Protocol for Human Exposure
For humans, the urgency of medical treatment cannot be overstated. Once clinical symptoms of rabies appear, the disease is almost always fatal. The “post-exposure prophylaxis” (PEP)—the series of vaccinations mentioned by health officials—must be administered immediately after a potential encounter.
Anyone who may have touched or been bitten by the bat on Logan Drive, or any bat in the affected area, is urged to grab the following steps immediately:
- Seek Medical Care: Go to a healthcare provider or emergency room immediately for evaluation.
- Contact Public Health: Call the Alameda County Public Health Acute Communicable Disease Program at 510-267-3250 to report the exposure and coordinate care.

Frequently Asked Questions Regarding the Fremont Alert
Is the entire city of Fremont at risk?
While the rabies virus is a general public health concern, the current door-to-door notifications and specific alerts are focused on the Glenmoor neighborhood, specifically around Logan Drive, where the positive case was identified.
What should I do if I find a dead bat?
Do not touch the animal. Contact local animal control or vector control services immediately to ensure the animal is collected and tested safely, as was done in the March 31 incident.
Can rabies be treated after symptoms start?
According to county health officials, rabies is a fatal disease. The only way to survive exposure is to receive vaccinations immediately before the virus reaches the central nervous system and symptoms manifest.
Why are puppies under 3 months specifically mentioned?
Particularly young animals may not have completed their full initial vaccination series, making them more susceptible to the virus if they encounter an infected animal.
The Alameda County Department of Public Health and Vector Control continue to monitor the situation. Residents are encouraged to stay tuned to official city communications for any further updates regarding wildlife health in the Glenmoor area.
