"Alaska Health Officials Expand Wastewater Virus Testing Amid COVID Pandemic"

Alaska health officials are expanding efforts to use wastewater testing as a tool to track the spread of viruses, including COVID-19, tuberculosis, RSV, flu, monkeypox, and noroviruses. Wastewater testing serves as an early warning system, detecting virus levels before symptoms appear, and has become crucial as fewer people are getting tested for COVID-19. The state is working to expand testing to rural areas and track other diseases, hiring a wastewater informaticist and planning to publish weekly data online. The University of Alaska Anchorage lab is also expanding its efforts to detect other viruses and hopes to use the data to inform public health decisions and resource allocation.

Promising Updates on Flu Vaccines' Effectiveness

However, mid-season data from the Southern Hemisphere suggest that the current season's flu vaccines for 2023-2024 provide good protection against the most serious outcomes. The vaccines reduced the risk of influenza-associated hospitalizations by 52% and the circulating influenza viruses were genetically similar to those targeted by the Northern Hemisphere's vaccine formulation. Despite this positive news, less than a quarter of hospitalized patients had been vaccinated, highlighting the need for health authorities to encourage influenza vaccination, especially for high-risk individuals.
