More L.A. cats appear to be infected with H5N1 bird flu

Experts believe three more cats in Los Angeles County have been infected with H5N1 bird flu. Two others succumbed to the disease earlier this month after drinking recalled raw milk from Fresno-based Raw Farm LLC dairies.

Of the three new sick cats, two died and one tested positive for influenza A, an unusual finding in domestic cats that haven't been exposed to infected birds or contaminated dairy products. The two that died couldn't be tested while they were alive, but experts believe it is likely their deaths were due to the H5N1 virus.

The three cats all lived in the same household...

...The three latest cats all exhibited respiratory illness, and have no known exposure to raw milk; investigators are looking into whether the animals ate raw meat.

The cats lived exclusively indoors, according to health officials.

People who had direct contact with the cats are being monitored for symptoms and have been offered antiviral medications. There have been cases of cat-to-human transmission of bird flu, according to researchers....

These herds are new: 661, 664, 665, 666 - so 4 new today added to yesterday's California herds dated the same date of Dec. 16.

December 17, 2024: CDFA Has Confirmed New Cases of H5N1 Bird Flu in California Dairy Herds and Released 56 Fully Recovered Dairies from Quarantine


SACRAMENTO, CA — Following an investigation by the California Department of Food and Agriculture (CDFA) and rapid disease detection by California Animal Health and Food Safety Laboratory System (CAHFS), the U.S. Department of Agriculture's (USDA) National Veterinary Services Laboratories (NVSL) has confirmed H5N1 Bird Flu in 311 dairies in the last 30 days in California. Since California's first detection of H5N1 Bird Flu in dairies, there have been a total of 645 infected dairies with 56 of those affected, fully recovered and released from quarantine. All quarantine released dairies will be placed on a surveillance list for weekly testing through creameries to maintain continued monitoring of the virus in California.

Flu surveillance flags probable H5 avian flu case in Delaware


Lisa Schnirring


Today at 4:26 p.m.

Avian Influenza (Bird Flu) An H5 avian flu case that the US Centers for Disease Control and Prevention (CDC) recently added to its probable list was initially flagged by routine flu surveillance.

In other developments, federal officials confirmed more H5N1 detections in diary cows, poultry flocks, and a few non-farm mammals, and Labcorp announced the launch of its molecular test for the virus in people.

Exposure unknown in Delaware's probable case


Tim Mastro, deputy director of communications with Delaware Health and Social Services, said in an email that the state's Division of Public Health identified a possible case of novel H5 during routine surveillance at the state public health lab, which immediately contacted the CDC for confirmation testing and guidance.

After multiple tests on the sample, the CDC notified Delaware health officials that it couldn't confirm the novel influenza A in the case.

The CDC had said a few days ago that the infection meets the case definition for a probable case and that there is no defined exposure. The CDC has now reported seven probable cases. The six others involve people who had exposure to cows or poultry. The number of lab-confirmed infections since the start of the year remains at 60, which includes 2 with unknown exposure.

More confirmations in cows, poultry, other mammals


In other developments, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed 7 more outbreaks in dairy cattle, all in California, raising the state's total to 645 and the national total to 860 across 16 states.

APHIS also added two more confirmations in poultry flocks, the one it recently noted in Louisiana backyard birds and an outbreak at a commercial turkey breeder hen facility in Barron County, Wisconsin.

Also, APHIS confirmed five more H5N1 detections in mammals, all with sample collection dates between the end of October and the first week of December. They include a house mouse and a domestic cat from Utah's Cache County, where outbreaks in dairy cattle and an egg-laying farm were reported earlier this fall. The detections also include two mountain lions, one in Arizona and the other in Washington, and a domestic cat in California's San Bernardino County.

Labcorp launches H5 test


Labcorp today announced that its H5 avian flu molecular test is now available for doctors to order, and it can be used to assess potential human exposure. The company said it developed the test with support from the CDC to expand access and testing capacity amid the ongoing outbreaks in dairy cattle and poultry, linked to a growing number of human cases, some with unknown exposure.

Testing with the Labcorp test requires collection of a nasopharyngeal sample that is sent to Labcorp for polymerase chain reaction (PCR) testing. The result is reported back to the doctor and patient.

omg....still adding to the list with confirmation date of Dec.. 10th. Why were these 2 herds (CA 606 & CA 634) not added to the rest of them on the same day? Is this on purpose?

1 new additional herd to the USDA list that was confirmed on Dec. 12th but was added today (17th). I have to go back several days now and always see if a herd has been back dated. This is ridiculous. There are 5 new herds listed today with the confirmation date of December 16.



confirmed on the 12th but listed today:

More herds added to the Dec. 10 & Dec. 11 list + 5 on Dec. 12. It is not appreciated that the USDA is releasing partial confirmation information on one day and then posting the rest of the confirmations on a different business day. It makes keeping track of developments more fuzzy. Please release all daily confirmations at the same time. There is no reason to post Dec. 10 confirmation over a 3 business day period. Is this on purpose?

Why is herd #CA 337 confirmation posted today? That herd number would indicate a test sample taken sometime in early November. Are there internal delays, re-testing, disorganization? I would expect some intermittent numbering as results are developed but look at the range of herd numbers posted today.....#337....then some 500s...then a few 600s up to #649. Not confidence building.

I needed to add the new additional Dec. 10 confirmations (posted on Dec. 13) attachments on a new post:












To be clear - the USDA posted more herd confirmations on Dec. 13 with the confirmation dates of Dec. 10 (5), Dec. 11 (3) and Dec. 12 (5) for a total of 13 more herds posted on Dec. 13.

County of Los Angeles Public Health
For Immediate Release:

December 12, 2024 Suspected H5 Bird Flu Detected in Los Angeles County Cats That Consumed Recalled Raw Milk


The Los Angeles County Department of Public Health is investigating two possible cases of H5 bird flu in cats that consumed recalled raw milk from Raw Farm, LLC.

The infected indoor cats consumed raw milk linked to a recall of raw milk and cream products prior to the onset of symptoms, which included lack of appetite, fever and neurologic signs. The infected cats died after severe worsening of their illness, and subsequently tested positive for Influenza A, a rare result in cats.

Public Health is considering these suspected H5 bird flu cases and is obtaining confirmatory testing. The nationwide H5 bird flu outbreak has seen other cats infected with the virus after consuming infected raw milk.

People who had direct contact with the cats are monitoring for symptoms and have been offered antiviral prophylaxis. There have been no human cases of bird flu associated with exposure to these cats yet identified. The investigation is ongoing.
