DHS cancels plans for BioWatch's automated air-monitoring system
Plans for the US government's "Generation 3" automated system to test the air for dangerous pathogens in US cities under the BioWatch program have been canceled over concerns about its cost and effectiveness, it was revealed recently.
Cancellation of the Gen-3 system was ordered on Apr 24 by Jeh Johson, secretary of the Department of Homeland Security (DHS), the Los Angeles Times reported. The information came from a memo circulated by Michael V. Walter, manager of BioWatch.
BioWatch has air monitoring stations in about 30 cities. Filters from the stations are collected daily and tested for pathogens, such as the bacterium that causes anthrax, that might indicate a bioterrorist attack. The Gen-3 system was described as a "lab in a box" that would automate the collection and testing, speeding detection of threats.
According to the Times, Walter said in his memo that DHS "remains committed to the BioWatch program and the importance of improving our early warning and detection technologies." And DHS spokesman S.Y. Lee said the cancellation reflected a commitment to "cost-effective acquisition without compromising our security."
The cancellation reverses a policy that continued for years under the George W. Bush and Obama administrations, the story noted.
In 2007 a DHS official told congress that Gen-3 would be "four times cheaper to operate" than the current system, the story said. But articles published by the Times in 2012 and 2013 revealed flaws in the system's durability and reliability.
Prototypes were installed in New York City's subway system in 2007 and 2008, but they were removed after city officials found their performance unsatisfactory. Also, field testing of another prototype in Chicago in 2011 showed that it could not operate more than a week at a time without manual servicing.
The problems prompted congressional hearings. In September 2012 the Government Accountability Office estimated that the annual operating costs for Gen-3 would be "about four times more" than for the existing BioWatch system, the Times reported.

Alberta declares three-region measles outbreak
Public health officials in Alberta have declared a measles outbreak in three regions after almost two dozen recent cases in the province, the Canadian Press reported yesterday.
The declaration allows immunization of babies 6 months to 1 year old who typically would not be vaccinated, according to a spokeswoman for Alberta Health Services. The outbreak regions are Edmonton, Calgary, and central Alberta.
The agency also recommended that children 4 years old and older receive their second dose of measles vaccine as soon as possible if they haven't yet received it.
In light of the cases during several straight weeks, spokeswoman Shannon Evans said the measure "was a necessary step to protect public health."
