Black Death Strikes China

Tuesday, August 4th, 2009

Around a dozen cases, 3 deaths, as pneumonic plague kills up its heels in NW China. This is a disease that hygiene can help prevent. Get rid of the rodents and their fleas and plague disappears.

Plague is spread in two main forms, pneumonic – which is the form reported in China, and bubonic. Pneumonic plague is spread like many respiratory diseases, by being coughed or sneezed on by a sick person.

Bubonic plague can be found in the United States, almost entirely in the Southwest. It is spread by the bites of fleas, usually fleas from rats, mice or other rodents. The number of human cases varies with the natural increases or decreases in rodent populations. The NIH reports 10-20 cases of bubonic plague in the U.S. on average each year. 1 of 7 cases is fatal.

Pneumonic plague appears as a rapid onset pneumonia, with all the related symptoms, fever, shortness of breath, coughing and sometimes bloody sputum. It is very contagious for people who have close contact with the patient. The Y. pestis bacteria cannot survive longer than about an hour in open air and sunlight so personal contact is the most risky.

Plague Kills Grand Canyon Biologist

This story is a prime example of the reason that EMS workers are told to use universal precautions for every patient. You cannot know what you may encounter.

Although plague is endemic west of the Mississippi — brought here in the 1800s by flea-infested rats on ships ferrying Chinese railroad workers to the USA — York had little reason to suspect it. Mountain lions usually stalk bigger game than rodents. But this lion had kittens that had to learn to hunt.

When York became ill, he visited the park’s clinic, Wong says. On Oct. 30, clinic staff diagnosed a flu-like illness and sent him home. It was there, three days later, that a roommate found him lying motionless on the couch.

Wong says York’s toughness and self-sufficiency may have cost him his life. “He was a tough guy. He gutted out more than you or I or almost anyone else would.”

Diseases Found in North America

The incidence of communicable diseases is such that they are unlikely to prove a hazard for international travelers greater than that found in their own country. There are, of course, health risks, but in general, the precautions required are minimal.

Certain diseases occasionally occur, such as plague, rabies in wildlife, including bats, raccoons, foxes, and other wild animals. Coccidioidomycosis is endemic in the southwestern United States and can occur in visitors to the area. Its incidence has increased in Arizona and California in recent years. Histoplasmosis is highly endemic, especially in the Mississippi, Ohio, and St. Lawrence River valleys. Sporadic cases and large outbreaks occur.

Cases of hantavirus pulmonary syndrome have been widely distributed in North America, with the greatest concentration in the western and southwestern United States. Infections in animals were reported in agricultural regions of the United States and Canada in 2006; infection in humans is rare.

Lyme disease is endemic in northeastern, north central (upper Midwest), and Pacific coastal areas of North America. West Nile fever was first documented in the United States (New York) in 1999 and has since spread throughout continental United States and southern Canada.

Outbreaks of diarrhea caused by enterohemorrhagic Escherichia coli O157:H7 have occurred in many areas and have increased in the past decade. Campylobacter and Salmonella are the most common causes of acute bacterial diarrhea.

Isolated cases of bovine spongiform encephalopathy (BSE/mad cow disease) have been reported in Canada and the United States. For more information, see http://www.cdc.gov/ncidod/dvrd/bse/ and http://www.usda.gov.

Outbreaks and cases of pertussis have been increasing for more than a decade.

Plague!

A campground at Natural Bridges National Monument has been closed because of bubonic plague detected among field mice and chipmunks.

Plague also has been found this spring in rodent populations at Mesa Verde National Park and Colorado National Monument.

Rangers plan to insecticides to kill fleas in the campground area. Humans usually contract bubonic plague after being bitten by fleas that have bitten infected rodents. The campground could be reopened as soon as next week.

Plague occurs throughout the West, but is concentrated in the Four Corners area of Utah, Colorado, New Mexico and Arizona. An average of 18 cases involving humans are reported each year in the United States, according to the federal Centers for Disease Control and Prevention. About one in seven victims die.
