The Public Health Agency of Canada has issued a “travel health notice” to its citizens who plan to travel to California. Childhood vaccination against whooping cough (pertussis) has dropped low enough to result in a 7-fold increase in the number of infections over the past year alone.
An increasing number of parents are opting out of vaccines, a trend that could threaten to reverse the preventive health gains we’ve made against certain infectious diseases this past century. How scary is that?
Incidentally, whooping cough can be lethal — killing a small percentage of kids who suffocate from the damage it does to the respiratory tract. For more information about whooping cough, I recommend the Mayo Clinic’s consumer health website.
To all the moms and dads out there, please vaccinate your kids. The benefits far outweigh any potential harms. And to you Canadians, make sure you’re vaccinated before you go to California.

Shingles (herpes zoster) is no fun. It usually begins with a couple of days of pain, then a painful rash breaks out and lasts a couple of weeks. The rash consists of blisters that eventually break open, crust over, and consolidate into an ugly plaque. It is localized to one side of the body and to a stripe of skin corresponding to the dermatomal distribution of a sensory nerve.
Very rarely a shingles infection can lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis) or death. More commonly, patients develop postherpetic neuralgia (PHN) in the area where the rash was. The overall incidence of PHN is 20%; after the age of 60 this rises to 40%, and after age 70 it rises to 50%. It can be excruciatingly painful, resistant to treatment, and can last for years or even a lifetime. Read more »

California recently declared an epidemic of whooping cough (pertussis) which resulted in the death of five infants under the age of 3 months. The pertussis vaccine, which is already given routinely to infants, is first given at 2 months of age, then 4 months and 6 months of age, with an additional booster at 15 to 18 months of age, and then again at 4 to 6 years old.
The vaccines for Bortella pertussis bacteria, which causes whooping cough, does not confer lifelong immunity. In other words, fully-vaccinated children who then become teenagers and then adults lose immunity, can acquire the infection and then spread it. Should babies acquire pertussis, as the public has discovered, it can be deadly. The persistent cough tires the baby, causes difficulty breathing, and can make them turn blue or cyanotic resulting in pneumonia or convulsions. According to CDC, about half of children aged 1 year and younger need to be hospitalized if infected with the illness. Although older children and adults can handle the cough, the infection can cause them to cough for weeks or months. Read more »

Remember “cooties” in grade school? You know, the germs or disease that girls gave boys or boys gave girls in grade school if they touched? Well, it seems they’re becoming an epidemic. Thank goodness someone checked for “cooties” on the Stanley Cup:
The NHL champion Blackhawks’ beloved trophy stopped by the Chicago Tribune newsroom, and so we took the opportunity to do something the Cup’s keeper said had never been done: We swabbed it for germs. We sent the samples to the Chicago lab EMSL Analytical, which found very little general bacteria and no signs of staph, salmonella or E. coli. “It’s surprisingly clean,” lab manager Nancy McDonald said. Just 400 counts of general bacteria were found, she said. By comparison, a desk in an office typically has more than 10,000.
No staph species detected? Hmmm. I think there was a sampling error…

On June 11, 2009, Dr. Margaret Chan, the director general of the World Health Organization (WHO), declared that the H1N1 flu that was then spreading around the world was an official pandemic. This triggered a series of built-in responses in many countries, including stockpiling anti-viral medications and preparing for a mass H1N1 vaccination program.
At the time the flu was still in its “first wave” and the fear was that subsequent waves, as the virus swept around the world, would become more virulent and/or contagious –- similar to what happened in the 1918 pandemic. This did not happen. At least our worst fears were not realized. The H1N1 pandemic, while serious, simmered through the winter of 2009-2010, producing a less than average flu season, although with some worrisome difference. Read more »
