Releases Findings of Gastroenteritis Outbreak at Wyoming Summer Camp |
|
The U.S. Centers
for Disease Control and Prevention (CDC) has released findings from
an E. coli outbreak, which occurred last summer at a Wyoming
youth camp. This report identifies Norovirus and Campylobacter
species as the etiologic agents. The first campers to experience
illness were children who attended camp during the week of June
25--July 1, 2006 with the first laboratory-confirmed case of Norovirus
on July 1, 2006.
A total of
141 (67.1%) cases were identified among the 210 interviewed campers.
Diarrhea was reported by 102 (72.3%) persons, vomiting by 92 (65.2%),
and stomach cramps by 89 (63.1%). The camp voluntarily closed
on July 19 as recommended by the Wyoming Department of Health (WDH)
until improvements in the camp's water and septic systems could
be implemented.
Investigators
of the outbreak believed that the large number of camp attendees
overburdened the septic system and created a heavy demand for water
from the wells, reducing the groundwater level and allowing septic
system effluent to contaminate the water that replenished the wells.
The shallowness of the wells and their proximity to the septic tank,
combined with the camp's location in a mountainous area with fractured
rock aquifers and little topsoil, also might have facilitated contamination
by allowing septic tank effluent to percolate to the wells through
fissures in the underlying rock formations.
An ongoing drought
in the area was also deemed a contributing factor allowing changes
in groundwater levels, facilitating contamination. In such instances
alternative waste water treatment methods might be necessary where
geologic conditions warrant. Officials suggest that before sending
their children to a summer camp, parents should inquire about recent
water-quality testing in the camp, particularly if it is located
in a rural area where similar systems are more likely to be encountered.

Summer E. Coli Outbreak

| In
Somalia, Displaced Face Threat of Cholera |
|
Dire humanitarian
conditions in the Somali capital of Mogadishu have worsened as a
result of an outbreak of cholera and acute watery diarrhea, based
on reports compiled by medical sources in the African nation affiliated
with the United Nations (UN) and African Union (AU). Homeless
camps in the capital were suffering the worst due to overcrowding
and lack of proper sanitation facilities.
The crisis
has been exacerbated by the hundreds of returning Somali residents
who had been driven from their homes by extended fighting. Hundreds
of thousands of civilians have been displaced in recent months due
to heavy fighting in the city. Reports indicate that most of the
patients are being cared for under trees and diseases are likely
to spread. Although the mortality rate remains low, with only
15 deaths since the outbreak in March, health officials have expressed
concern about the potential for rapidly escalating death rates.
Cholera is an
acute, diarrheal illness caused by infection of the intestine, according
to the U.S. Centers for Disease Control and Prevention (CDC). Approximately
one in 20 infected persons has severe disease characterized by profuse
watery diarrhea, vomiting, and leg cramps. In these persons,
rapid loss of body fluids leads to dehydration and shock. Without
treatment, death can occur within hours.

| University
of Arizona Announces 10-minute Test for E. Coli |
|
A new technology
developed at the University of Arizona (UA) may be able to produce
test results for E. coli and other pathogens in 10 minutes
rather than the hours or days current detection devices offer. The
new testing methods could prevent widespread illness and even death
by quickly detecting microscopic pathogens in food and water.
Traditional
culture based testing can often take 24 to 48 hours for results.
A second type of test, the Polymerase Chain Reaction (PCR), takes
six hours and also requires lab facilities. The new testing can
be completed in 10 minutes from start to results, meaning that contaminated
food can be identified before it is made available to the public,
reducing illness and death. Researchers report the test kit
is 99 percent accurate, and has shown no problems with false-positive
tests.
Before the test
kit can be brought to market it must meet U.S. Environmental Protection
Agency compliance tests. A number of labs have already indicated
interest in purchasing the Innovis testing kit, according to media
reports. The technology has been patented and Innovis is a business
created by students in the McGuire Center for Entrepreneurship at
UA's Eller College of Management.

| AWWA,
EPA Band Together to Promote Utility Water |
|
The American
Water Works Association (AWWA) and the U.S. Environmental Protection
Agency (EPA) are gearing up to help water utility managers across
the nation celebrate Drinking Water Week 2007, set for May 6-12.
Drinking Water Week has been celebrated for more than 30 years.
The EPA is serving as a campaign co-sponsor.
The theme of
this year's event is "Only Tap Water Delivers." Drinking Water Week
is designed to recognize the value of a safe, reliable community
water supply, according to the AWWA. This year the campaign is designed
to provide utilities with tools to help them communicate with consumers
and decision-makers about the value of water service as well as
encourage and equip public officials to speak about the importance
of investing in water service and resources, according to the AWWA.
