The H5N1 fowl flu seems to be stampeding by dairy farms in California, the nation’s largest milk producer. Over the weekend, the full variety of confirmed contaminated cow herds stunningly doubled, going from 17 final Thursday to 34 Monday morning, based on state and federal officers.

With the brand new tally, California now ranks second amongst all affected states for having probably the most herds with avian influenza. Solely Colorado, which has adopted bulk milk-tank surveillance, has extra, with 64 herds confirmed. California’s excessive rating is even supposing it solely reported its first three contaminated herds on August 30, whereas the dairy outbreak was first confirmed on March 25 and thought to have begun late final 12 months.

To this point, 232 herds in 14 states have been contaminated with the fowl flu.

In an announcement final week, California officers mentioned the batch of herds that examined constructive have been “focused for testing as a consequence of elevated dangers from their current connections with the preliminary affected premises.” They known as the constructive outcomes “not surprising” and reported that they match with the state’s plans of discovering infections as early as doable. “Early detection supplies the chance to work with farms to shortly implement enhanced biosecurity, cow care, and worker safety.”

When the state’s first contaminated herds have been introduced, California Division of Meals and Agriculture Secretary Karen Ross touted the state’s preparations and readiness. “Our in depth expertise with [highly pathogenic avian influenza] in poultry has given us ample preparation and experience to deal with this incident,” Ross mentioned. She additional assured dairy farmers that they’re approaching the outbreak with the “utmost urgency.”

Troubling transmission

The information comes as public well being consultants are involved about a puzzling case of H5 fowl flu in an individual in Missouri, who had underlying medical situations however no recognized publicity to animals. The case is the 14th human an infection amid the dairy cow outbreak this 12 months. The entire 13 prior infections have been in farmworkers recognized to be uncovered to contaminated animals: 9 in poultry staff and 4 in dairy staff. However Missouri has not reported H5N1 in dairy herds and hasn’t had current outbreaks in poultry services, both.

Whereas the Missouri case has recovered, well being officers are stumped about how that individual grew to become contaminated. In a press briefing earlier this month, an official with the Facilities for Illness Management and Prevention instructed the case could possibly be a “one-off.” However, the CDC has reported that one other individual within the family with the Missouri case fell in poor health on the similar time, suggesting a doable widespread publicity to the virus. That family contact was not examined for flu and has additionally since recovered. The CDC is now conducting serological testing to see if the family member has developed antibodies in opposition to the fowl flu, indicating a earlier an infection.

The CDC has additionally reported {that a} well being care employee who interacted with the affected person fell in poor health, however examined detrimental for flu. On Friday, the CDC reported that a second well being care employee grew to become in poor health with a light respiratory sickness after interacting with the Missouri case however was not examined for flu and recovered earlier than the investigation started. The CDC will supply serological testing for that well being care employee, too.

Whereas there is no proof of human-to-human transmission but, well being consultants concern that there’s not sufficient testing—of case contacts, animals, or farmworkers—and transmission goes unseen. Because the wily influenza virus spreads throughout the nation to new mammalian species, it features new alternatives to adapt to people and trigger extra extreme illness. Influenza consultants have lengthy feared that the virus has pandemic potential.
