Published: February 25, 2025
The global health landscape faces a complex array of challenges, from a novel coronavirus emergence to deadly outbreaks of influenza and listeria. Health officials are closely monitoring these situations, working to understand the risks and implement effective responses. A newly discovered bat coronavirus in china, a severe flu season in California with over 900 deaths, and a multi-year listeria outbreak traced to frozen shakes are among the most pressing concerns. These issues demand immediate attention and coordinated action to protect public health.
A newly identified bat coronavirus in China, named HKU5-CoV-2, has ignited concerns among researchers about the potential for another pandemic.According to a report in the South China Morning Post, this virus shares a concerning similarity with SARS-CoV-2, the virus responsible for COVID-19.Both viruses target the same human receptor, angiotensin-converting enzyme (ACE2), which is crucial for viral entry into human cells.
researchers collected the HKU5-CoV-2 strain from a small subset of hundreds of Pipistrellus bats swabbed across China’s Guangdong, Fujian, Zhejiang, Anhui, and Guangxi provinces. Analysis revealed that it belongs to a distinct lineage of coronaviruses that includes the one causing Middle East respiratory syndrome (MERS) and is only distantly related to SARS-CoV-2, the strain of coronavirus that caused the COVID-19 pandemic. Bloomberg reported that the HKU5-CoV-2 strain can enter human cells by binding to the ACE2 receptor — a protein on the surface of many cells — mirroring the mechanism used by SARS-CoV-2 to infect cells, replicate, and spread.
While HKU5-CoV-2 is considered much less powerful than SARS-CoV-2,its ability to infect human cells has raised alarms. Researchers suggest that HKU5-CoV-2 could potentially led to human-to-human or even cross-species transmission, warranting further inquiry and monitoring.
Avian Influenza (Bird Flu) Updates
The ongoing threat of avian influenza, commonly known as bird flu, continues to be a concern for public health officials and the agricultural sector.recent studies and outbreaks have highlighted the complexities of this virus and the challenges in controlling its spread.
A non–peer-reviewed study published on the preprint server bioRxiv suggests that highly pathogenic avian influenza (HPAI) virus shed in poultry droppings can be transmitted by the wind. The report centers on a February 2024 outbreak of H5N1 avian flu among unrelated commercial poultry farms located about 8 kilometers (5 miles) apart in the Czech Republic during the 2023-24 HPAI season. While other experts acknowledge that wind transmission cannot be ruled out, proving it definitively remains an critically important challenge.
In Canada, researchers at the Canada Food Inspection Agency (CFIA) discovered a mutated H5N1 avian flu strain resistant to the antiviral drug oseltamivir (Tamiflu) on eight chicken farms in British Columbia in October 2024.This “exceptionally rare” mutation, as described in a research letter published in Emerging Microbes & Infections, raises concerns about the effectiveness of current antiviral treatments for avian influenza. The virus had a neuraminidase surface protein derived from a low-pathogenic flu virus from a North American lineage.
The potential for a bird flu pandemic was also discussed on WAMU’s “1A” on Feb. 20, by KFF Health News editor-at-large for public health Céline Gounder.
Severe Influenza Season Claims Lives in California
California is experiencing one of its worst influenza seasons in recent years, with a significant number of deaths reported across the state.According to a report released Friday by the California Department of Public Health, more than 900 Californians have died from the flu this season, including 15 children. The Los Angeles times reported that most of the influenza victims — 701 — were over 64 years old, which aligns with the understanding that the illness disproportionately affects older people.
In Minnesota, health officials are warning health care facilities about a rare but serious complication of influenza. the Minnesota Department of Health said a Twin Cities child under 2 years old with the flu developed a case of influenza-associated acute necrotizing encephalitis (ANE). CBS News reported that ANE causes rapid deterioration of the brain tissue. The department said ANE is “rare, however, the morbidity and mortality are high.”
Listeria Outbreak Linked to Frozen Shakes
A multi-year listeria outbreak has been traced to frozen shakes sold to nursing homes, hospitals, and other institutions, according to the Food and Drug Administration (FDA). The New York Times reported that as 2018, at least 11 people have died from the outbreak, and dozens have been hospitalized. Despite previous investigations, the source of the bacteria had remained elusive until now.
Rare Case of Rat Lungworm
In a separate and unusual case,doctors discovered parasitic “rat lungworm” in a 30-year-old New England woman’s brain. The Washington Post reported that the woman’s symptoms began with a burning sensation in her feet, which spread and worsened over several days. A trip to the emergency room initially revealed no obvious cause, highlighting the diagnostic challenges posed by such rare infections.
