US flu markers climbing; More H5N1 poultry outbreaks
Filed Under:
Avian Influenza (Bird Flu); Influenza, General
US flu activity continues steady rise
For the week ending Jan 1, most US flu indicators rose, with the season still dominated by H3N2 and now affecting a range of age-groups and hitting the northeastern and central regions hardest, the US Centers for Disease Control and Prevention (CDC) said today in its latest weekly update.
Nationally, the percentage of clinic visits for flulike illness rose to 4.8%, up from 3.8% the previous week. The CDC has said that other circulating respiratory viruses are likely contributing to the respiratory illnesses that health providers are seeing. The percentage of respiratory samples that tested positive for flu dropped to 3.8%, down from 6.2% the week before.
Thirty-one states are reporting very high or high flu activity, another marker that tracks clinic visits. The number is up sharply from 19 states reported the previous week.
The cumulative hospitalization rate for flu rose to 2.6 per 100,000 population, up from 1.8 per 100,000 population the week before. However, the CDC said the level for this point in the season is well below the rate seen at this point in the four flu seasons that preceded the pandemic.
No new pediatric flu deaths were reported, keeping the total at two.
The CDC said the flu season is just starting and urged people to get vaccinated, noting that early indications show that uptake is down this season, compared with the last season.

H5N1 strikes poultry in Niger and Vietnam
Two countries—Niger and Vietnam—reported new highly pathogenic H5N1 avian influenza events in poultry, according to the latest notifications from the World Organization for Animal Health (OIE).
Niger reported an outbreak at a layer farm near Niamey, the country's capital. The event began on Dec 31, killing 1,400 of 18,575 susceptible birds. Its last H5N1 outbreak occurred in July 2021.
Elsewhere, Vietnam reported five outbreaks in village birds from five different provinces: Binh Phuoc, Nghe An, Ninh Binh, Quang Tri, and Tay Ninh. The outbreaks started between Nov 19 and Dec 28, and taken together, the virus killed 6,810 of 18,144 birds.
In other avian flu developments, European countries continue to report highly pathogenic avian flu in wild birds, including Portugal with two H5N1 events and Denmark with an outbreak involving H5N8.
