What’s in the Air? Rethinking Airflow and Infection Risk in Health Care

Image generated using Google’s Nano Banana 2, 4/20/26.

For nurses, environmental infection prevention is often framed around visible conditions such as high-touch surfaces, shared equipment, and visible dirt. In my experience, airflow and ventilation are not topics that receive significant emphasis in nursing education or orientation. While this may vary by setting, many nurses are left to learn these concepts in practice rather than through formal training.

With the recent COVID-19 and measles outbreaks, there has been more focused attention placed on contaminated air as a risk to patient safety. In my work with health care teams across settings, I’ve found that while nurses are highly attuned to cleaning and disinfection practices, airflow and ventilation are often assumed to be “handled” by the facility operations staff. In reality, these systems depend heavily on how the environment is used at the bedside. Small, routine actions—like leaving a door open or introducing a fan—can unintentionally disrupt carefully designed controls.

This gap in awareness among clinical staff matters. While the Centers for Disease Control and Prevention continues to report progress in reducing health care-associated infections (HAIs), these infections remain at a persistent risk for patients. Expanding the nurse’s focus on the […]

What’s Lurking in the Sink? Rethinking Water as an Infection Risk in Health Care

Nurses play a primary role in patient safety through direct care and through the environments in which care is delivered. While clinical responsibilities are well defined, the nurses’ role in promoting a health care environment that prevents health care–associated infections (HAIs) is not always clear.

A recent report from the Centers for Disease Control and Prevention (CDC) revealed that U.S. hospitals saw meaningful declines in several major HAIs in 2024, including Clostridioides difficile (C. diff) infections, catheter-associated urinary tract infections (CAUTIs), central line–associated bloodstream infections (CLABSIs), and methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Despite the obvious progress, each day, approximately one in 31 hospitalized patients and one in 43 nursing home residents contract at least one HAI in association with their health care. This alarming statistic underscores the need for frontline vigilance by nurses in every clinical setting.

When the Environment Works Against Us

Infection prevention is often framed around what we can see—dirty floors and high-touch surfaces, visibly soiled equipment, and stained linens. Some of the most consequential risks in health care are not visible. One emerging area of concern is the role of health care water systems as reservoirs for pathogens. Surprisingly, it’s not dirty water that’s being scrutinized, but clean […]

Turmoil at the CDC Endangers Public Health

Sowing distrust in the science behind CDC guidance.

The turmoil roiling the Centers for Disease Control and Prevention (CDC) was on full view last Thursday at the Senate hearing convened to review the Trump administration’s health care agenda. The proceedings quickly descended into a shouting match as senators, both Republican and Democrat, challenged health secretary Robert F. Kennedy Jr. on his policies and recent actions, particularly regarding vaccines and the firing of CDC director Susan Monarez. Kennedy defended his positions while attacking the agency, as he has done repeatedly, accusing its medical experts and scientists of corruption and collusion with the pharmaceutical industry.

In late August, Kennedy called Monarez into his office and pressured her to resign, a mere 29 days after appointing her. At the time of her appointment, Kennedy lauded Monarez as “a public health expert with unimpeachable scientific credentials,” stating that he had “full confidence in her ability.”

According to White House press secretary Karoline Leavitt, Monarez was fired because […]

Ticks and Tick-Borne Diseases: A Comprehensive Nursing-Focused Overview

Virtually all of us who have spent time in the outdoors have either heard about or experienced an encounter with a tick. Diseases transmitted through the bite of a tick represent a growing health concern in the United States and around the world. Tick bites can affect individuals who live in, work in, or travel to wooded, grassy, or brush-filled environments. Ticks are generally more active during warmer months of the year (usually April through September), but they can be active any time the temperature is above freezing. Therefore, taking precautions can be close to a year-round activity, including an increased emphasis during vacation travel when the climate may differ from that of your usual environment. Nurses play an essential role in patient education, prevention, early recognition, clinical management, and public health surveillance of these diseases—and their credibility and trusted relationships enable impactful opportunities.

The following summary outlines key facts about tick biology and transmission, clinical manifestations of major tickborne diseases [TBDs], prevention strategies, post-bite care, public health reporting, and updates on vaccines—particularly for domestic and international travelers.

A Tumultuous Seven Weeks for Public Health in the United States

Editor’s note: AJN news director Karen Roush, PhD, RN, FNP, will be providing regular updates on AJN Off the Charts about the details and implications of rapid and potentially momentous changes being made by the Trump administration to the public health system in the United States.

It’s been a tumultuous seven weeks since President Trump’s inauguration. Changes in leadership and priorities have swept across every federal department, bringing uncertainty and disruption. Trump signed more than 70 executive orders (EOs) in his first month in office, including orders to erase diversity, equity, and inclusion efforts from federal agencies and the military (EO 14151); limit the rights of transgender people and declare that only two “sexes,” biological males and females, would be recognized by the federal government (EO 14168); end birthright citizenship (EO 14160); and further limit access to abortion (EO 14182). Elon Musk’s Department of Government Efficiency, known as DOGE, has fired tens of thousands of federal employees, dismantled entire agencies, including USAID, and pulled grant funding from universities, nongovernmental organizations, and the National Institutes of Health (NIH).
