State health officials are working with state and local partners to investigate several cases and clusters ofSalmonella infections that appear to be linked to eating pork.

The ongoing investigation of at least 56 cases in eight counties around the state includes food served at a variety of events.

Disease investigators continue to explore several sources from farm to table, and are focused on an apparent link to pork consumption or contamination from raw pork.

Salmonellosis, the illness caused by infection with Salmonella, can cause severe and even bloody diarrhea, fever, chills, abdominal discomfort, and vomiting. Serious bloodstream infections may also occur.

As of July 23, the 56 cases include residents of King (44), Snohomish (4), Mason (2), Thurston (2), Pierce (1), Grays Harbor (1), Yakima (1), and Clark (1) counties.

Five of the cases were hospitalized; no deaths have been reported. All were infected with the same strain of Salmonella bacteria.

The disease investigation shows a potential exposure source for several cases was whole roasted pigs, cooked and served at private events.

The source of contamination remains under investigation by state and local health officials and federal partners. Continue reading

West Nile virus infection confirmed in Washington resident

From Washington State Department of Health

The first in-state acquired case in 2015 identified this week

Benton CountyOLYMPIA — A Benton County woman is the first Washington resident known to be infected with West Nile virus in the state this year.

The woman in her 50’s was likely exposed near her home.

Most in-state acquired human and animal cases are exposed in south-central Washington, but the mosquito species that transmit the virus are found throughout the state.

Nationally, six states have reported human West Nile virus infections this year. Tests have also confirmed the virus in Washington mosquito samples so far this season from Franklin, Yakima and Grant counties.

Regardless of where you are, avoiding mosquito bites is the best way to prevent getting infected.

Health officials recommend a few simple precautions to reduce your chances of getting mosquito bites, such as:

  • staying indoors around dawn and dusk when mosquitoes are most active,
  • using insect repellent when spending time outdoors, and
  • wearing long sleeves and pants when mosquitoes are active.

Be sure that door and window screens are in good condition so mosquitoes cannot get indoors.

Reducing mosquito habitat around the home by dumping standing or stagnant water from old buckets, cans, flower pots, or old tires, and changing water in birdbaths, pet dishes, and water troughs at least twice a week are also effective ways to reduce the chances of being bitten. Continue reading

Measles led to death of Clallam Co. woman; first in US in a dozen years

Tragic outcome for immunocompromised patient shows need for community protection

Measles Virus

The death of a Clallam County woman this spring was due to an undetected measles infection that was discovered at autopsy.

The woman was most likely exposed to measles at a local medical facility during a recent outbreak in Clallam County.

She was there at the same time as a person who later developed a rash and was contagious for measles.

The woman had several other health conditions and was on medications that contributed to a suppressed immune system.

The last confirmed measles death in the United States was reported in 2003.

She didn’t have some of the common symptoms of measles such as a rash, so the infection wasn’t discovered until after her death. The cause of death was pneumonia due to measles.

This tragic situation illustrates the importance of immunizing as many people as possible to provide a high level of community protection against measles. Continue reading

Waterborne diseases pose a risk during swimming and other outdoor fun

Share

From the Washington State Department of Health

infant-swimmingSwimming pools, beaches, lakes, and streams provide an opportunity to cool off during a summer that’s warmer than usual.

Yet germs in the water can make people sick, especially young children, elderly people, and people with weak immune systems.

Chlorine in swimming pools kills most germs, but some types of germs can resist chlorine for many days.

Germs that can cause waterborne illness include Cryptosporidium, Giardia, Shigella, E. coli, and norovirus. In the past three years, three outbreaks of waterborne illness have been reported to state health officials – two in lakes and one in a swimming pool.

“It’s important to do all we can to protect ourselves and others from waterborne diseases when we take a dip into local pools, lakes, and rivers,” said State Epidemiologist for Communicable Disease Dr. Scott Lindquist. “Stay out of the water if you’re ill or have recently had diarrhea.” Continue reading

National HIV Testing Day is a reminder to get the facts, get tested, and get involved to take care of yourself and your partners.

An estimated 1.2 million people in the United States are living with HIV, and that number grows by almost 50,000 every year. One in eight people who have HIV don’t know it. That means they aren’t getting the medical care they need to stay healthy and avoid passing HIV to others.

CDC has found that more than 90 percent of new HIV infections in the United States could be prevented by testing and diagnosing people who have HIV and ensuring they receive prompt, ongoing care and treatment. Early linkage to and retention in HIV care is central to managing HIV and promoting health among all people living with HIV. HIV medicines can keep people with HIV healthy for many years, and greatly reduce the chance of transmitting HIV to their sex partners.

Get the Facts

Protecting yourself and others against HIV starts with knowledge. Knowing the facts about HIV will help you make informed decisions about sex, drug use, and other activities that may put you and your partners at risk for HIV.

  • Learn the basics about HIV, how to prevent HIV transmission, and the steps you can take to protect yourself and others.
  • Talk about what you learn with your friends and other people who are important to you.
  • Empower even more people via social media. Share your new knowledge with your friends online.
Find more information about HIV testing, and who should be tested, on CDC’s HIV Testing Basics web page.

Get Tested

The only way to know if you are infected with HIV is to get tested. Continue reading

Washington state kindergarten vaccination rate below target goal

Share

Boy gets shot vaccine injectionOnly 83% of kindergarten students in Washington state arrive in the fall up-to-date on their immunizations, the Washington State Department of Health report.

This is well below the target goal of 95%, the level that is usually sufficient to halt the spread of infectious diseases such as measles through a community. None of the individual vaccines required for school meet this goal.

The low vaccination rate is of particular concern in light of recent outbreaks of measles and whooping cough, diseases which can be prevented with timely vaccination, health officials said.

About one in twenty, 4.5%, Washington state kindergarten students opted out of vaccinations due to medical, personal, or religious reasons. Washington has historically had high exemption rates for kindergarteners. Although exemption rates have come down since they peaked in 2008, but the improvement has leveled-off for the past few years.

In Washington, all recommended vaccines are available at no cost for kids through age 18 from health care providers across the state.

Although providers may charge an office visit fee and an administration fee for the vaccine, a family that can’t afford to pay can ask their regular provider to waive the administration fee.

For help finding a health care provider or an immunization clinic, call your local health agency, visit the ParentHelp123 resource finder, or call the Family Health Hotline at 1-800-322-2588.

Watcom County E coli outbreak linked to fairgrounds dairy barn

Share

Escherichia Coli_NIAID E Coli BacteriaThe bacteria that sickened 25 people in Whatcom County has been traced to a dairy barn on the   Northwest Washington Fairgrounds, an investigation by county, state and federal health officials has concluded.

“All of the ill people either attended the Milk Makers Fest between April 21 and 23 at the Northwest Fairgrounds; helped with the event between April 20 and 24; or were close contacts of people associated with the event,” according to a final report on the outbreak released by the Whatcom County Health Department.

“Most of the ill people were children, including older children who helped with the event. More than 1,000 children from primary schools in Whatcom County attended the event on these days,” report said..

The bacteria, a virulent form of the bacteria Esherichia coli, called Shiga toxin-producing E. coli O157:H7, can cause severe diarrhea and in some cases a condition called hemolytic uremic syndrome, or HUS, that can lead to kidney failure. Contamination of the fairgrounds most likely occurred before the Milk Makers Fest.

Investigators identified 25 people confirmed cases:

  • 9 of these cases were considered secondary cases (the ill person didn’t attend the event but had close contact with someone who did attend).
  • 10 people were hospitalized.
  • 6 people developed HUS.

No one died as a result of the outbreak.
