Is whooping cough going around the community?
– Eric, Big Sky
Cold symptoms run rampant in the wintertime, and this year has been no exception – especially when it comes to the contagious cough running around Big Sky.
Since 2004, there has been a frightening resurgence of pertussis, or whooping cough in the U.S., and 2010 tallied the most cases in more than 50 years, with 27,550 nationwide. We’re still experiencing what the Centers for Disease Control has called “the worst whooping cough epidemic in 50 years,” though case numbers are dropping due to increased vaccination rates.
Whooping cough is a highly contagious upper respiratory illness caused by Bordetella pertussis. In the pre-vaccine era, children under 10 predominantly contracted the illness, stricken with prolonged cough and one or more of the classic symptoms: a “whoop” noise between coughs, severe coughing fits, and cough followed by vomiting.
It can be hard to know if a community is experiencing a pertussis outbreak, because affected individuals tend not to seek treatment during the first stage – confirmation of the illness, done through lab testing, is only reliable during the first 2-4 weeks. This is also the time period when medicine can actually shorten the course of the illness. Unfortunately, most cases go undetected.
If treated after two weeks, antibiotics may not shorten the illness but are likely to decrease the spread of the bacteria. Most infected individuals clear the illness within 3-4 weeks without treatment.
Since the 1990s, pertussis has affected mostly adolescents and adults, due largely to waning immunity. While their symptoms can be less severe than in children, these age groups can carry the illness to children and infants who are at higher risk of severe illness and death. Once infected, the typical incubation period is 7-10 days. This is much longer than the common cold, where incubation takes about three days.
Infections have three phases of illness. In the first stage, which lasts 1-2 weeks, runny nose, malaise and mild cough are common; high fever is atypical. Other early symptoms include excessive eye watering or redness.
The hallmark symptom occurs during the second stage, which starts around week two: severe, forceful coughs during exhalation, followed by a vigorous inhalation that sounds like a “whoop.” Often a person will have paroxysms, or fits of these distinctive coughs.
Since their airways are smaller, the whooping noise is more pronounced in young children, who may also stop breathing between coughing spells. This can be alarming, since the paroxysms can cause a person to vomit or pass out. In adolescents and adults, this period can last 2-3 months. Finally, within two more weeks, the symptoms subside.
If the illness is recognized, antibiotics are prescribed. However, neither natural infection nor vaccination offers life-long immunity, so following vaccination schedules is critical. The childhood vaccine is called DTaP (diphtheria, tetanus and acellular pertussis) and is given at 2, 4, 6 and 18 months of age, and at 4 and 11 years of age. An infant less than 2 months old is at high risk of pertussis infection and death.
To help protect this population, doctors recommend all pregnant women have a booster during their third trimester and repeat vaccination for every pregnancy. A pregnant mother passes on antibodies to the unborn child, offering protection until the child receives the first vaccine.
Since immunity wanes years after vaccination, it’s necessary for adults to get boosters, as well. The adult vaccine is called Tdap (tetanus, diphtheria and acellular pertussis). Tdap is now routinely given at least once after age 18. If you are unsure if your recent tetanus booster was a Tdap, get the Tdap vaccination immediately. This will help maintain immunity and reduce the possibility of passing the illness to a child.
See your medical provider if you suffer from a cough for longer than a week or show typical symptoms of whooping cough. If you’ll be spending time with a new baby, help protect it from pertussis by getting your vaccine.

We all are familiar with using a limited palette, but do you use one? Do you know how to use a limited palette to create different color combinations? Are you tired of carrying around 15-20 different tubes when you paint plein air? Have you ever wanted to create a certain “mood” in a painting but failed? Do you create a lot of mud? Do you struggle to achieve color harmony? All these problems are addressed in John’s workbook in clear and concise language!
Based on the bestselling “Limited Palatte, Unlimited Color” workbook written by John Pototschnik, the workshop is run by Maggie Shane and Annie McCoy, accomplished landscape (acrylic) and plein air (oil) artists,exhibitors at the Big Sky Artists’ Studio & Gallery and members of the Big Sky Artists Collective.
Each student will receive a copy of “Limited Palette, Unlimited Color” to keep and take home to continue your limited palette journey. We will show you how to use the color wheel and mix your own clean mixtures to successfully create a mood for your paintings.
Each day, we will create a different limited palette color chart and paint a version of a simple landscape using John’s directives. You will then be able to go home and paint more schemes using the book for guidance.
Workshop is open to painters (oil or acrylic) of any level although students must have some basic knowledge of the medium he or she uses. Students will be provided the book ($92 value), color wheel, value scale and canvas papers to complete the daily exercises.
