CDC’s Special Pathogens Branch recently diagnosed a case of Marburg hemorrhagic fever in a U.S. traveler, who returned from Uganda back in January 2008 [SPB posting]. This person had visited the famous “python cave” in Maramagambo Forest, Queen Elizabeth Park, western Uganda. Fortunately, no one seems to have been infected from this patient when she was hospitalized. But we are never more than 24 hours away from the next new infectious disease.

The current Salmonella Typhimurium outbreak associated with a peanut processing plant in Blakely, Georgia, appears to have begun in September 2008, and was first detected in mid-November 2008 by DNA fingerprinting of Salmonella in public health labs across the country [last blog link]. The broad distribution of peanut butter and peanut paste shipped to food manufacturing companies from this single plant throughout the country has triggered the recall of nearly two hundred food products and exposed a critical factor supporting the continued emergency of food-borne outbreaks.

The Enteric Diseases programs at CDC have been collaborating with state public health officials, the USDA-Food Safety and Inspection Service, and the US Food and Drug Administration (FDA) to investigate a multi-state outbreak of human infections due to Salmonella serotype Typhimurium affecting almost 400 persons. There are numerous interesting features of this outbreak that highlight the complex issues I discussed recently for foodborne outbreaks. In this case, there was an early unrelated, but overlapping outbreak, several PulseNet patterns involved in the outbreak, a State Health Department being the first to pull the trigger for a product advisory, and a contaminated ingredient that is in many foods.

Ebola-Reston [initial identification] virus is a mystery. Although quite deadly in monkeys, this Ebola cousin doesn’t appear to cause human illness. And who knows how it got to or independently evolved in the Philippines – a good 7,000 miles and really big ocean away from its Zaire, Sudan, Cote D’Ivoire, and Bundibugyo brethren in Africa. If that wasn’t enough, our colleagues at Plum Island recently suspected it as the cause of disease in some sick pigs for the first time from the Philippines that happened to be submitted for testing for Porcine Reproductive and Respiratory Syndrome (PRRS).
