Top 5 Infectious Disease News Stories Week of September 6-11

Beyond the Virus: Long COVID’s Neurological Toll

Since the onset of the COVID-19 pandemic, the persistence or emergence of neurological symptoms after clearing SARS-CoV-2 infection has become a significant health challenge for both patients and clinicians globally. The effects of postacute sequelae of SARS-CoV-2 infection (PASC), often referred to as Long COVID, can be debilitating and last for months after the initial infection. Symptoms may include fatigue, neuropsychiatric issues, sleep disturbances, sensorimotor problems, cognitive impairment or brain fog, reduced taste or smell, hearing loss, and ocular symptoms.

Assessing the Relationship Between C-diff Risk and Antibiotic Exposure

C difficile remains a significant healthcare challenge globally, with over 225,000 hospitalizations in the US alone, and more than half of these cases associated with recent antibiotic exposure, highlighting the strong link between antibiotic use and the risk of this healthcare-associated infection. As investigators explore the connection between various classes of antibiotics and C difficile infection (CDI), the broader context of infectious disease challenges becomes apparent. With rising COVID-19 cases, an ongoing H5N1 outbreak, and a global health emergency related to mpox, the array of public health threats is extensive, yet frequently overlooked issues such as healthcare-associated infections, antimicrobial resistance, and CDI underscore the urgent need for focused attention and action.

E coli Outbreak Linked to Contaminated Lettuce

The study on the E coli outbreak in the UK underscores the increasing impact of climate change on public health and food security. Eurosurveillance reports a significant outbreak of Shiga-toxin producing Escherichia coli (STEC) O157, with contaminated lettuce identified as the probable source. This outbreak, which occurred between September and October 2022, led to 259 confirmed cases of gastrointestinal illness and emphasizes the critical link between climate change and food safety.

USP26: Key Driver in HBV-Induced Liver Cancer

Despite recent advances in systemic treatments for hepatocellular carcinoma (HCC), patients with Hepatitis B Virus (HBV)-induced HCC still face a poor prognosis. This study investigates the role of deubiquitinases in HBV-positive HCC and uncovers potential new therapeutic targets by establishing a direct link between HBV infection, deubiquitinase activation, and HCC development. It identifies the gene USP26 as a crucial factor in this process and suggests that targeting USP26 could offer a promising approach for developing new treatments.

Strategies for Improving Pandemic Preparedness

At the World AMR Congress last week, Syra Madad, DHSC, MSc, MCP, CHEP, chief bio preparedness officer for New York City Health and Hospitals, highlighted the importance of early surveillance systems and diagnostic innovations in improving pandemic management and response. She emphasized the necessity of integrating public health and healthcare surveillance to boost preparedness and effectively address pandemic risks.
