Study finds inadequate mask use among health care workers early in 2009 H1N1 outbreak

01.12.2011
Inadequate use of masks or respirators put health care workers at risk of 2009 H1N1 infection during the earliest stages of the 2009 pandemic in the U.S., according to a study published in the December issue of Infection Control and Hospital Epidemiology, the journal of the Society of Healthcare Epidemiology of America.

The study, led by the Centers for Disease Control and Prevention (CDC), tracked 63 Southern California health care workers who had contact with six of the first eight laboratory-confirmed 2009 H1N1 cases in the U.S. Because these contacts happened before the 2009 H1N1 outbreak had been widely reported, the cases shed light on how well health care workers protect themselves before a direct epidemiological threat becomes evident.

The investigation found that 9 of the health care workers tracked became infected with the 2009 H1N1 virus, likely from contact with infected patients. Twenty of the 63 health care workers reported that they had worn a mask or respirator at least once when in contact with patients, and no one from that group became infected with 2009 H1N1. Meanwhile, 43 workers reported never using a mask around patients, and all 9 infections occurred in workers from this group.

Overall, mask and respirator use was disappointingly low, the researchers report. Only 19 percent reported using a mask during every patient encounter. Use was especially low among outpatient workers, who also made up the majority of those who became infected with 2009 H1N1.

"The findings highlight the challenge of getting health care personnel to routinely wear Personal Protective Equipment," Jenifer Jaeger, MD, MPH, Associate Pediatrician, Massachusetts General Hospital, said. "The study also suggests that greater attention to infection control and preparedness, particularly among outpatient workers, is needed."

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
