Respiratory virus activity in the United States is still elevated but continues to decline, with only 6 jurisdiction reporting high levels, down from 10 the previous week, the Centers for Disease Control and Prevention (CDC) said today in its data updates.

Several regions below their flu baselines

Flu markers declined for the third week in a row, following a prolonged rise after the winter holidays, according to the CDC's latest FluView report. Test positivity and hospitalizations declined last week, while overall deaths and outpatient visits for flulike illness remained level. Though the national level remains slightly above the outpatient visit baseline, six parts of the country are now below their regional baselines.

Of respiratory samples that were positive for flu at public health labs, 61.1% were influenza A and 38.9% were influenza B. Of subtyped influenza A samples, half were the 2009 H1N1 strain and half were H3N2. Seven more pediatric flu deaths were reported, raising the season's total to 133. Two were due to influenza, with 5 were caused by influenza B. The CDC confirmed 184 pediatric flu deaths last season.

Lower levels for all COVID, RSV markers

In its latest updates for COVID, the CDC reported declines in severity indicators (hospitalizations and deaths) as well as early indicators (test positivity and emergency department visits).

Wastewater SARS-CoV-2 detections remain low and declining in most parts of the country, except for a very small rise in the Northeast.

For respiratory syncytial virus (RSV), activity continues to decrease across the country, and 8 of 10 regions are now below the 3% test-positivity threshold, suggesting that the RSV season is ending in those areas.

Hospitalized COVID-19 patients with neurologic manifestations at the time of admission had worse long-term outcomes at various time points up to 3 years compared to matched controls in a study published yesterday in PLOS Medicine. 

The study is based on outcomes seen in patients at the Montefiore Health System in the Bronx, New York, in March and April 2020. Follow-up data were captured through January 2023. The health system was one of the first epicenters of the COVID-19 pandemic in the United States

The researchers compared 414 patients with COVID-19 who had significant neurological manifestations with 1,199 patients matched for age and COVID-19 severity score but without neurologic manifestations. Significant neurologic manifestations included stroke, seizure, and vertigo.

Higher death rates 

A higher percentage of patients in the neurologic cohort were discharged to acute rehabilitation (10.39% versus 3.34%), the authors said. The incidence of readmission for any reason was also higher for the neurologic group (65.70% versus 60.72%). 

Overall, patients in the neurologic cohort were more likely to die post-discharge compared to controls (hazard ratio, 2.35; 95% confidence interval, 1.59 to 3.47), with higher death rates at 6 months, 1 year, and 3 years post-hospitalization. 

Patients with significant neurological findings during COVID-19 hospitalization were more likely to have worse outcomes.

"Patients with significant neurological findings during COVID-19 hospitalization were more likely to have worse outcomes at 3-year follow-up compared to propensity matched controls," the authors concluded. "Improved understanding of the long-term outcomes of patients with COVID-19 with neurological involvement could help to develop effective screening methods and innovative interventions to address the potentially high burden of care among these COVID-19 survivors."

A new US Department of Health and Human Services (HHS) white paper outlines progress it has made toward preventing and lessening the impact of drug shortages—particularly the vulnerable generic injectable drugs used in hospitals—while acknowledging its efforts are only part of the solution. 

"All across our Department, we are working to ensure that millions of Americans will have access to medication, treatment, and services that save lives and improve health outcomes," HHS Secretary Xavier Becerra said in a department press release.

"That's why advancing and implementing solutions to the nation’s drug shortages are so important, and why we want members of Congress and all actors in the supply chain to consider and act on the policy options presented in today’s white paper."

Authorities, resources needed to incentivize market

HHS and its agencies have been working to better track the drug supply chain and respond to disruptions, including:

• The establishment of a new supply chain resilience and shortage coordinator role to implement strategies to shore up supply chains for drugs and other medical products
• The publication of guidance to boost supply chain transparency and consider other long- and short-term solutions.
• A joint HHS and Federal Trade Commission request for information on how group purchasing organizations (GPOs) and drug wholesalers contribute to generic drug shortages.
• A $500 million Administration for Strategic Preparedness and Response (ASPR) investment to support domestic manufacturing of active pharmaceutical ingredients, as well as an exploration of how to return overseas manufacturing of essential medicines, medical countermeasures, and their ingredients to the United States.
• Proposals for policies to foster a diverse drug supply chain through Medicare payments.

Additional authorities and resources are needed to reward investment in supply chains through the development of a manufacturer resiliency assessment program and hospital resilient supply program, HHS adds.

Drug shortages have been a problem around the world for decades for reasons such as the interference of supply chain "middlemen" and a generic-drug price "race to the bottom" that provides little incentive for redundancy and resilient manufacturing, distribution, and purchasing.

• Zoonotic (ie, from animals), human-to-human close contact, and human-to-human sexual transmission are occurring in the Democratic Republic of the Congo (DRC) mpox outbreak, which involves a different clade than the one that continues to circulate globally, the European Centre for Disease Prevention and Control (ECDC) said today in an epidemiologic update. Children make up 70% of cases and 88% of deaths, and their infections are mainly due to household contact with infected adults and spillover from small animals. The ECDC added that the DRC's sexual transmission cases seem to be concentrated among sex workers—both women and men—and their contacts in the mining areas, which don't have direct travel connections to Europe and pose a limited risk of spread. So far, no recent clade 1 cases have been confirmed outside of the DRC, but local spread to Rwanda and Burundi is possible.
• As part of the response to cholera outbreaks in multiple countries, the World Health Organization (WHO) today announced the first shipments of rapid tests for the illness, starting with Malawi. The WHO said more than 1.2 million tests will be deployed to 14 countries and funded through Gavi, the Vaccine Alliance. The goals are to help speed detection, monitor outbreaks, gauge vaccine campaign effectiveness, and target future vaccination efforts.
• Afghanistan has reported its first wild poliovirus type 1 (WPV1) case of the year, according to the latest weekly update from the Global Polio Eradication Initiative (GPEI). The patient is from Kunar province in the northeast. Afghanistan and Pakistan are among the countries in which WPV1 is still endemic. Pakistan had earlier reported two WPV1 cases this year. Elsewhere, Nigeria reported three more cases involving circulating vaccine-derived poliovirus type 2 (cVDPV2), bringing its total for the year to seven. The cases are in Kano, Kaduna, and Katsina states.
