Last month, a state of emergency—which has now been halted by state court—was declared in nearby Rockland County, New York, barring children who hadn’t been vaccinated against measles from public places. The unprecedented step made worldwide news and highlights the public health measures being taken to stem the six currently ongoing measles outbreaks in the United States.

Measles was eliminated in the United States in 2000, but outbreaks have occurred since, increasingly so in recent years. The CDC reported this week that almost 400 cases of measles have been confirmed in 15 states during the first three months of this year alone. This is the second-greatest number of reported cases since eradication of the disease. The most—667 cases—occurred in 2014.

Public health authorities are clear about the cause of these outbreaks: people contract measles abroad and bring it back to the United States, where groups of people who are unvaccinated are particularly susceptible to developing and spreading this highly contagious disease. Up to 90% of […]

Legionnaires’ Outbreak in New York City: Some Basics for Nurses

By Betsy Todd, MPH, RN, CIC, AJN clinical editor

11148_loresIn the largest U.S. outbreak of Legionella infection since 1976, when there were 221 cases and 34 related deaths in an outbreak at a Philadelphia American Legion convention, more than 113 cases of the disease have been diagnosed in New York City since mid-July. Twelve people have died.

Legionnaires’ disease is neither rare nor exotic; it is a type of community-acquired pneumonia (it can also be hospital acquired). Symptoms include fever, cough, and progressive respiratory distress. Legionella can also cause a milder, flulike illness known as Pontiac fever that generally resolves without treatment. Because many cases of Legionnaires’ disease are never actually diagnosed, mortality rates are difficult to determine, but the rate currently is estimated at 5% to 30%.

The CDC estimates that 8,000 to 18,000 people are hospitalized with Legionnaires’ disease each year in the U.S., yet only about 3,000 cases are diagnosed and reported. Most cases of Legionnaires’ disease are sporadic, unlinked to any outbreak. The infections often are not recognized as Legionnaires’ disease, for several reasons.
