Community Acquired Methicillin Resistant Staphylococcus Aureus on the Rise

Siskiyou County Residents have been recognizing the need for medical care for questionable staphylococcus infections. Despite community awareness and medical treatment, community associated methicillin resistant staph aureus (CA-MRSA) cases have increased. These infections often appear like a bug bite or minor skin infections, such as a pimple or boil. It also may begin as a cut that is swollen, or a blister filled with fluid, later becoming crusty. Skin infections are the most common. Although staph bacteria are common on skin and in the nose, the common strain does not usually cause a serious infection. When a bacterium becomes resistant to antibiotics, it is difficult to treat and can spread to other people through skin-to skin contact. MRSA, first identified in the 1960’s was mainly found in hospitals and nursing homes. About ten years ago community acquired MRSA became more common. This new type of MRSA is continuing to spread, especially among children and adults who do not have medical problems. Although it is not a reportable disease, Siskiyou County Public Health is monitoring the status through physician reports. We are concerned that primary prevention is needed.

Factors that have been associated with the spread of MRSA skin infections include: close skin-to-skin contact, openings in the skin such as cuts or abrasions, contaminated items and surfaces, crowded living conditions, and poor hygiene. There are two ways you can have
MRSA. You can have an active infection or you can be a carrier. Health Officer, Dr. David Herfindahl has informed schools, preschools, child care providers, fitness clubs and karate clubs that persons infected with MRSA can spread the disease to others with skin to skin and indirect contact. Primary prevention begins by recommending that individuals with skin rashes or open wounds cover the lesion with clothing or a bandage when in contact with others. Persons with active MRSA infections should not participate in contact sports until sores have healed. It is recommended that persons with active MRSA do not attend a public gym, sauna, hot tub or pool until sores have healed. Manicures, massages and hair cuts should be postponed until MRSA sores have healed.

Equipment, personal items, clothing, toys, towels, bedding, telephone, door knobs, or any surface that has been in contact with the bacteria can be a source of transmission for up to a week. It is important to clean them often and completely. In households and in public places where MRSA staph is suspect, Public Health recommends the following cleaning procedures to help prevent the transmission:

Use a disinfectant to regularly (daily) clean surfaces. Pay attention to items that are frequently touched, such as equipment surfaces, benches and chairs, doorknobs, toilets, sinks, counters, etc. Hand washing and preventing others from coming into contact with your infection are the best way to reduce spread to others. Households should be cautious not to share towels, toothbrushes, razors, or other personal items. Wipe the surface or object with an appropriate disinfectant and let it dry. We recommend that you:

  1. Put on disposable gloves,
  2. Wipe up any fluids with a paper towel,
  3. Throw the paper towel in the trash,
  4. Clean the surface thoroughly using a disinfectant and a paper towel,
  5. Throw the paper towel in the trash,
  6. Wipe the surface again with the disinfectant and let it dry for at least 30 seconds,
  7. Throw the paper towel in the trash,
  8. Remove your gloves and throw them in the trash, and finally
  9. Wash your hands or use an alcohol-based hand sanitizer.
Persons suspecting antibiotic resistant staph should contact their medical provider. Following a diagnosis, it’s critical to take antibiotics as prescribed. Do not share antibiotics with others; this can increase development of antibiotic resistant staph. If symptoms of active skin infection continue after treatment, patients must contact their medical provider to be re-evaluated. A second course of antibiotics and or an antibacterial nasal spray may be recommended. After the infection is healed you may still be a MRSA carrier. Notify all future medical providers that you may be a MRSA carrier. Medical providers sometimes refer to the carrier status as being colonized; this means you still have MRSA bacteria on your skin and in your nose. You may not get sick or have any more skin infections, but you can spread MRSA to others.

MRSA is a serious infection that can become life-threatening if left untreated. If you or someone in your family has been diagnosed with MRSA, there are steps you need to take now to avoid spreading it to your family and friends. MRSA carriers need to make adjustments in their lifestyle to reduce these chances. The brochure, “Living with MRSA” can be downloaded here:

Blue Green Algae

The summer recreation season is upon us. County residents and visitors are visiting our local waterways to enjoy camping, boating, kayaking, and river rafting activities.

The Siskiyou County Public Health Department reminds residents and visitors that Irongate Reservoir, Copco Lake and Lake Shastina are known to have seasonal blooms of blue-green algae (cyanobacteria). Irongate Reservoir and Copco Lake are currently experiencing a bloom. Blooms typically occur between June and October when temperatures rise and water conditions are favorable for algal growth.

Samples from Irongate Reservoir and Copco Lake taken in late July indicate high algae cell counts and visible algal scums along the shoreline. Sampling from previous years indicates that these algae are capable of releasing toxins that are potentially harmful to human health. Related to those blooms, Siskiyou County provided brochures at the affected waterbodies and provided public service announcements about potential health concerns.

Blue-green algal blooms are common phenomena that occur world wide. The State of California has embarked upon a process to evaluate the potential health risks associated with blue-green algal toxins, determine appropriate water sampling and monitoring procedures, identify strategies to control toxic blooms, and to better inform the public about health and environmental concerns. Siskiyou County is an active participant in this statewide effort and will continue to keep abreast of information and issues concerning toxic blue-green algal blooms.

While there have been no documented cases of human illness associated with blue-green algae in California, studies around the world show that recreational exposures to toxic blue-green algae might result in eye irritation, allergic skin rash, mouth ulcers, vomiting and diarrhea, and hay-fever like symptoms. There is little information available about the potential human health effects of long-term exposure to blue-green algae.

The presence of blue-green algae in a water body does not necessarily mean toxins are always present. However, identifying the presence of toxins is an expensive and difficult process and one that may involve many days to weeks before results are available. Therefore, it is prudent for recreational users to adhere to the following precautions with regard to blue-green algae blooms in Siskiyou County waterbodies:
  • Avoid wading and swimming in water containing visible blooms or water containing algal scums or mats.
  • Carefully watch children to ensure that their exposure and accidental water ingestion is minimized. Because of their small body size and weight, children who ingest a small amount of water can receive a higher relative exposure to toxic substances than adults who ingest the same amount.
  • Do not drink, cook or wash dishes with untreated surface water under any circumstances. In addition to blue green algal toxin concerns, open surface waters can contain harmful bacteria and parasites.
  • If you accidentally swallow water from a bloom and experience one or more of the following symptoms you should contact your physician and the Public Health Department.
    • Stomach cramps
    • Vomiting
    • Diarrhea
    • Fever
  • Fish caught in these reservoirs may be consumed after removing guts and liver, and rinsing filets in tap water.
In addition, residents and visitors are reminded that domestic animals and livestock can be affected by blue-green algal blooms. There are documented animal poisonings and deaths associated with exposure and consumption of algal toxins. Special care should be taken to ensure that animals do not drink the water or swim through heavy scums or mats. Consumption of algal toxins occurs when animals lick their fur after wading/swimming in blue-green algal blooms.

The public may contact the Siskiyou County Public Health Department for additional information by calling (530) 841-2100. For information about the State of California’s activities related to blue-green algae blooms, visit these web sites:

Stay Cool in Extreme Heat

Siskiyou County temperatures have slightly cooled this week and there have been no reports of residents needing hospitalization related to the heat wave. In the state of California however, Stanislaus and other counties with record breaking temperatures have experienced some heat related deaths. The California Health Alert Network has released an extreme heat alert for the state.

Dr. David Herfindahl, Siskiyou County Public Health Officer, encourages Siskiyou County residents to use common sense and watch out for family, friends, and neighbors who may be at risk for heat exhaustion, heat stroke, heat cramps, sunburn or heat rash. The following tips may help you stay cool:

  • To sustain normal body temp of 98.6 F use fans, air conditioners and/or frequent baths and showers.
  • Stay hydrated by drinking plenty of water. Avoid caffeinated and alcoholic beverages. Sports drinks replenish salt and minerals, and are recommended after exertion. People who have epilepsy, heart, kidney or liver disease, may be on fluid-restricted diets and should consult a doctor before increasing liquid intake.
  • Eat light, cool and easy to digest foods that support the body’s normal temperature.
  • When outside, protect face and head by wearing a wide-brimmed hat and dress in loose-fitting, lightweight, and light –colored clothes that cover as much skin as possible.
  • Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
  • Never leave children or pets in closed vehicles.
  • Stay indoors as much as possible and limit exposure to the sun.
In addition to preventing heat related illness, early detection and treatment is important. Those most prone to heat related illness are people with high blood pressure, chronic illness, the elderly, homebound people, and children under the age of 5 years. Onset of symptoms may be hours to several days after exposure to high temperatures and inadequate fluid replacement. The first sign could be confusion or acting strange accompanying high body temperature (103 degrees or above). Additional symptoms include: red, hot and dry skin, rapid, strong pulse, throbbing headache, dizziness, and nausea.

In the case of heat related illness the first step is to reduce body temperature:
  • Begin by taking the person to a shady area.
  • Cool them rapidly with water or by whatever method is available. For example immerse in cool water; place the person in a cool shower, spray the person with cool water from a hose, sponge the person with cool water. Continue to cool them with a fan while keeping them wet.
  • Monitor body temperature and continue cooling efforts until the body temperature drops.
  • Promote rehydration with electrolyte rich fluids like sports drinks, no alcohol.
  • Seek medical assistance as soon as possible.

Avian Influenza (a.k.a. Bird Flu)

Avian flu, also known as bird flu, is a respiratory disease that can infect humans and birds. Avian flu is very contagious among birds and if transmitted to humans can be deadly.

Outbreaks of avian flu are currently present in many Asian counties and Russia. Because these viruses do not commonly infect humans, there is little or no immune protection against them in humans. If the avian flu virus changes to more easily infect humans and becomes easily spread person to person, “influenza pandemic” (worldwide outbreak of disease) could begin. At present, there is no vaccine available to protect against avian flu.

Siskiyou County Public Health has developed an Influenza Pandemic Response Plan which would be used to guide our response efforts should the need arise.
The Health Department continues to encourage everyone to practice good respiratory hygiene measures for any colds or flu like illness:

  • Wash your hands frequently
  • Cover your cough or sneeze
  • If you are sick, stay home from work or school
