Superbugs and Sewage at the Beach
By Ralph Morris, MD, MPH, and Joan B. Rose, PhD

We seem to be reading and writing a lot about superbugs—antibiotic resistant bacteria that are responsible for at least 2 million infections (including healthcare-associated infections acquired while receiving medical treatment in a hospital) and 23,000 deaths each year in the US.1 But the recent discovery of the “superbug enzyme” NDM2 in bathing seawaters in Ireland impacted by untreated sewage/wastewater3 brings this global public health issue even closer to home. After all, unless you work in the healthcare field, most of us avoid hospitals but go out of our way to spend a day at the beach!

Diarrheal outbreaks linked to swimming are a persistent challenge for aquatic venues

Crypto-Editorial-Cartoon

Americans will soon head to the pool as Memorial Day weekend marks the unofficial start of the swimming season, but a new survey reveals that there may be more in the pool than just water.

The survey, conducted on behalf of the Water Quality and Health Council, found that 1 in 4 adults (25 percent) would swim within one hour of having diarrhea, half of adults (52 percent) seldom or never shower before swimming in a pool, and that 3 in 5 adults (60 percent) admit to swallowing pool water while swimming.

These results are concerning to experts from the U.S. Centers for Disease Control and Prevention (CDC), the Water Quality and Health Council, and the National Swimming Pool Foundation® (NSPF®), given that waterborne outbreaks of diarrheal disease caused by the germ Cryptosporidium (or … READ MORE >>

A New Resource to Help Curtail Norovirus: Pictogram Disinfection Posters
By Linda F. Golodner

Norovirus, the dreaded illness popularly known as the “stomach bug,” is the leading cause of gastrointestinal upset in the US. According to the US Centers for Disease Control and Prevention (CDC), there are 19 to 21 million cases of norovirus in the US annually. The highly contagious virus is an unwelcome visitor in schools, day care and elder care settings, offices, sporting venues, cruise ships and more. norovirus prevention poster norovirus cleanup posterNorovirus presents the greatest health risk to young children and the elderly. Globally, the economic burden of norovirus hovers around $60 billion in healthcare costs and lost productivity.

The Perfect Pathogen

As described by CDC’s Dr. Aron J. Hall in an “Editor’s Choice” article in The Journal of Infectious Diseases in May, 2012, norovirus may be the “Perfect Pathogen,” because, among other factors, it:

According to a recent Science Daily report, thousands of brown howler monkeys in a forest in southeastern Brazil have died of yellow fever.

Yellow fever, a deadly scourge transmitted by mosquitoes that has impacted the course of human history time and time again, is on the rise in Latin America. The first yellow fever death in Brazil in 17 years occurred in January 2017, when a young person who worked in the jungle succumbed to the disease. A recent Pan American Health Organization (PAHO) “Situation summary in the Americas” reported that since the current outbreak began in Brazil in December 2016, there have been over 1,400 confirmed or suspected cases and at least 234 deaths in six states of that country. Suspected and confirmed yellow fever cases have also been reported in Colombia, Ecuador, Peru, Bolivia and Suriname.

A Guest Post by Terry Arko

Algae Swimming PoolAlgae in the swimming pool is an unwelcome sight, but one that usually can be dealt with effectively. The following “color-coded” tips can help you or your pool service professional identify and eliminate, or at least control, the most common types of algae. It is important to follow manufacturers’ directions for using and storing all pool chemicals.

It is the easiest type of algae to remediate, but left unaddressed, green algae can worsen to the point of obscuring the floor and steps of the pool and potentially even a struggling bather, raising the drowning risk. Eradicate green algae by raising the chlorine level or adding an algaecide. Following treatment, it is important to run the filtration system continuously to clear the water by trapping the READ MORE >>
