First Day, First Cold

For many, next Tuesday (September 3rd) is the first day back to school.   For my son, the emails of who his teacher will be next year arrived and with it, a flurry of texts to all my mom friends to find out who else was going to be in his class.  He got lucky; several of his buddies are with him.  A few of his friends, however, did not get so lucky.  I expect there will be a lot of grumbling around the dinner table on Tuesday as we try to pry out how the first day of school went.

The first day of school signifies a number of things; the end of summer, back to school shopping, nerves over meeting your new teacher and entering a new grade where you know the work is going to get harder.  For parents it also signifies cold and flu days. 

According to the CDC, 40% of children aged 5 – 17 missed 3 or more school days last year because of illness or injury.  If you count up all the students, that means nearly 22 million school days are lost due to colds and 38 million school days are lost due to the flu each year.  Although 3 days may not seem like a lot to our children, I’m sure that for many of you, 3 days of staying home with a sick kid seems like an eternity and invariably we, as the caretakers, end up getting sick.  Thankfully, it’s not that hard to keep germs at bay.

Teach Cough and Snot etiquette because 10,000 is the number of bacteria in a sneeze:
  • To avoid spreading germs, teach your child to cough into their elbow and not their hand.  This helps minimizing a germ-laden hand from touching all of the high touch surfaces.  
  • Pack tissue in your child’s bag or send a box of tissue they can keep at their desk so that they can blow their nose and dispose of the contents, rather than wipe their nose with the back of their hand and increase the chance for their secretions to be left on another surface for someone to touch.

Teach hand hygiene, because cold and flu germs can survive on surfaces for 72 hours:
  • Teach your children early the importance of washing their hands, especially before they eat and always after they have blown their nose or coughed into their hand.
  • Help your child’s teacher keep the classroom healthy by donating alcohol-based hand sanitizer.

Help keep the classroom clean, because on average, your kid touches 300 surfaces in 30 minutes:
  • This is not just the job of the teacher or custodian.  Send wet wipes with your child’s lunch and have them get into the practice of wiping down their desk top before they eat.  The more frequently the desk top is wiped the less chance germs have to stay on the surface and make your child sick.
  •  Provide sanitizing wipes to your child’s teacher for their use in the classroom.  The more readily available they are, the easier it is to wipe down high touch surfaces that everyone in the class touches, which will help stop the spread of germs.

  • Vaccination is one of the most effective ways to stop the spread of disease.  Before heading off to school, make sure your child’s vaccinations are up-to-date and that they get the annual flu shot.

You can be sure that on Tuesday, aside from taking the obligatory first day of school picture, I’ll be “reminding” my son to wash his hands and help keep the classroom clean!

Does Time Matter?

Has anyone ever told you “slow and steady wins the race”?  Even as a child I was an avid reader.  I had a large volume of Aesop’s Fables.  I quite literally read that book to death.  One of my favorites was The Hare and the Tortoise.

The Hare was once boasting of his speed before the other animals. "I have never yet been beaten," said he, "when I put forth my full speed. I challenge any one here to race with me."
The Tortoise said quietly, "I accept your challenge."
"That is a good joke," said the Hare; "I could dance round you all the way."
"Keep your boasting till you've beaten," answered the Tortoise. "Shall we race?"
So a course was fixed and a start was made.
The Hare darted almost out of sight at once, but soon stopped and, to show his contempt for the Tortoise, lay down to have a nap.
The Tortoise plodded on and plodded on, and when the Hare awoke from his nap, he saw the Tortoise just near the winning-post and could not run up in time to save the race.
Then said the Tortoise: "Plodding wins the race."

What does this do with cleaning and disinfection?  Well, as with many things, it takes time to do things right. There is enough published evidence to support the fact that when cleaning and disinfection is not completed correctly, or rushed, corners are cut which leads to adverse outcomes.  The question becomes: how much time does it take to clean and disinfect a patient room? 

The Association for the Healthcare Environment (AHE) recommends 20 – 45 minutes should be dedicated for terminal cleaning of a room.  A recent study by Chopin et al. investigated whether increased time spent on terminal cleaning would in fact lead to improved disinfection.  Surprisingly, it did not.  The study included 3 arms in which housekeepers were given 25mins, <45mins or >45mins to clean a room. They found that time spent beyond 25mins did not affect disinfection of the high-touch surfaces tested in the study.  In fact, the longer the time spent cleaning, the higher the post-cleaning bioburden was found to be.  The results could be due to random chance or may be a result of different cleaning activities, such as cleaning more surfaces without focusing on properly applying the disinfectant used.

As the researchers indicated, their study did not include observing environmental services (EVS) staff cleaning, so achieving contact time and product application was not recorded.  Again, in recent years a fair number of studies have been published investigating the role that contact time has in ensuring disinfection is achieved.  In general, the longer the contact time the harder it is to achieve the level of kill desired in healthcare facilities.  Similarly, there are different disinfectant chemistries that while contact times may be short their active ingredients dry so quickly that they cannot achieve the contact time as approved by the Health Canada or the EPA.

Does this mean we can skimp on the time we give our staff to clean?  No.  What it continues to highlight is that we need to find that balance between time (both contact time and the time given to clean rooms) and the process used by EVS to clean and disinfect.

Pigs’ Ears – a Tasty Treat and Health Hazard

If you’re a pet lover you may be among those who like to spoil their pets.  My cats get the occasional treat, but being cats they’re finicky and the organic, meat-only healthy treats that cost an arm and a leg don’t pass muster.  They prefer the easy-to-find on sale Temptations Cat Treats.  I have also spent a fair chunk of change on fluffy, plush cat beds.  It was a waste of money.

Dog lovers have a never-ending supply of treats they can pick up for their beloved canine friends, from rawhide and animal bones to pigs’ ears and raw food.  If you think you dog may like it, you can probably find it.  Unfortunately, pet treats and raw food does have some pitfalls and can adversely impact not just your pet’s health, but yours as well.   Case in point, pig ears sold as dog treats in 33 states are being recalled due to an outbreak of Salmonella. At least 127 people have now been stricken with the bacteria, with 26 of them hospitalized.   Thankfully no one has died.

Salmonella can affect animals eating contaminated products as well as the humans who handle the sickened animals or the infected product. Affected pets may become lethargic and have diarrhea, fever and vomiting.  Dog owners who have come in contact with the pig ear treats should see if a doctor if they experience high fever (temperature over 102˚F), blood in stool, diarrhea, or frequent vomiting that prevents keeping liquid down, and are concerned about the symptoms. People infected with Salmonella are usually ill for 4-7 days and recover without treatment.

Some key recommendations from the CDC include:
1.  Do not feed any pig ear treats to your dog. Throw them away in a secure container so that your pets and other animals can’t eat them.
·     Even if some of the pig ears were fed to your dog and no one got sick, do not continue to feed them to your dog.
·     Wash containers, shelves, and areas that held any pig ear dog treats with hot, soapy water. Be sure to wash your hands after handling any of these items.
2.  Shop safely
·      Always wash your hands thoroughly with soap and water after touching unpackaged dog food or treats, including products in bulk bins or on store shelves.
3. Take extra care around young children
·     Children younger than 5 should not touch or eat dog food or treats.
·     Young children are at risk for illness because their immune systems are still developing and because they are more likely than others to put their fingers or other items into their mouths.

Thankfully, as a vegetative bacteria, Salmonella spp. are among the easier-to-kill pathogens.  Until recently, Salmonella was one of the 3 main bacteria that had to be tested in order to receive a Hospital-Level disinfectant designation by the EPA.  While it is no longer required to be tested, virtually every consumer and professional product carries the claim due to its importance and association with foodborne illnesses.

If you have any pig ears at home, please take care and make sure your home is Salmonella-free!

Cleaning, a Good Investment that Saves Lives

Do you ever feel like you’re bashing your head against a wall or like a salmon swimming upstream? Having been in the infection control arena, focusing on cleaning and disinfection, I often wonder why we have to repeat the same things over and over. Why do we keep having to prove the things we know to be true and know that work over and over and over again?

A recent article published in ICHE titled “Sustained improvement in hospital cleaning associated with a novel education and culture change program for environmental service workers” concluded that the program the researchers introduced was able to address environmental service worker’s knowledge gaps, challenges and barriers resulting in behaviour change and sustained improvements in cleaning. I don’t mean to sound callous or disrespectful of the researchers, but this is not rocket science.

In June 2011, in my “To Clean or Not to Clean”, I referenced a collection of articles published by APIC, where the take home message was cleaning is important. Cleaning needs to be done right the first time, and that cleaning saves lives. Looking back through history, Florence Nightingale, during the Crimean War (1853 – 1856), identified the link between overcrowding, hygiene and poor patient outcome and by instituting a cleaning program and increasing the space between patients, saw a marked decrease in infection transmission. 

In June 2012, a guest blogger, Rick Wray’s blog “Complexities of cleaning a paediatric hospital environment” talked to the fact that achieving optimal cleaning requires an understanding of the complex interplay of chemistry, human factors and behavioural science involved in cleaning processes. He further discussed a program they had at their facility where assorted hospital staff were partnered with a member of our cleaning staff to learn from and to work with them to clean patient rooms. One senior leader became aware of the pride and diligence of the staff member with whom he was partnered. She was reluctant to let him do the cleaning; not because it was a job beneath his usual position but because he wouldn't do it well enough and she would have to clean up behind him.  

In December 2014, in my blogHey! Hey! Ho! Ho! Apathy has to go!when it comes to cleaning and disinfection there are just as many people who believe they cannot affect change so they do nothing, and just as many people again that plainly think cleaning and disinfection is someone else's responsibility.  However, based on another review of published literature by Donskey to determine if we had sufficient evidence to prove that improved cleaning and disinfection could reduce HAIs, the conclusion was that, "Although the quality of much of the evidence remains suboptimal, a number of high-quality investigations now support environmental disinfection as a control strategy. Based on these data, current guidelines for pathogens such as C. difficile, MRSA, VRE, and norovirus emphasize the importance of environmental disinfection as a control measure." 

These are but a few examples of the work the infection prevention community has completed to link the importance of cleaning and disinfection to the reduction in HAIs. The work has investigated best practices to ensure the cleaning processes used will meet the needs of our healthcare facilities and there are several studies that highlight the importance of providing training to our EVS staff and elevate them to a higher level to support the fact that they are a crucial part of our infection prevention program.

In reviewing this study, we have proven yet again that cleaning when completed effectively by skilled and trained staff, can directly impact the lives of patients.  If we know it, and if we have proven it time and time again, why can’t we get the C-suite or the wallet holders to understand the importance of cleaning and disinfection and the importance of having a skilled environmental services team? How do we get them to understand that this investment will save money and more importantly save lives?

State Fair Nightmares

August is a bitter sweet month.  We have jokingly been telling my son he only has 30 days until school starts.  It’s fun to bug him, but then you realize that August has arrived and summer vacation is quite literally a month away from being over!  While summer may be drawing to a close, August marks another change in season – City or State Fair season! 

I’ve always loved a good summer or fall fair.   As a country kid, I could be found showing horses and cows and not to brag or anything, I may have won a ribbon or two for my beloved Belgium belted rabbit, Mr. Boots or my white and ginger guinea pig Sparky.  For those that may be looking for an event that can pair education with cotton candy, funnel cakes and fried food, there are a few things to consider to ensure you keep yourself, your family and your animals safe.

Case in point, 1 child has died and 3 others were sickened by E. coli after coming into contact with animals at the San Diego County Fair.  The source of E. coil has not been confirmed but the children all visited the animal areas or the petting zoo.  As a result of the infections, public access to animal areas was closed including the petting zoo.  While this is just one example, between 1996 to 2012 about 200 outbreaks involving animals in public settings were reported to the CDC.  The National Association of State Public Health Veterinarians (NASPHV) has put together a number of recommendations as a way to minimize outbreaks, infections and deaths:

1.       Contact with animals should only occur in settings where measures are in place to reduce potential for spread of disease (e.g. access to hand washing stations).
2.       Disseminate educational and training materials to venue operators (e.g. infection control training and guidelines).
3.       Sample collection to ensure that animals do not carry pathogens that can transmit to humans.
4.       Information on facility design to reduce potential for contact with manure.
5.       Avoid contact with pre-weaned calves, reptiles, amphibians and live poultry for children under the age of 5.
6.       Signage to clearly communicate the importance of hand hygiene.
7.       Do not provide animal feed in containers that can be eaten by children (e.g. ice cream cones).
8.       Disinfect the area, at least once per day.

Being a farm girl, I am a proponent of people-animal interactions and not just the cute baby animals, but all animals, as learning where our food comes from and how farmers raise animals is important.  Farm fairs are also a time where farmers get to show off their prized animals.  To some, it may seem strange or boring to watch a ring full of cows or pigs, but let me tell you, winning can increase the worth of the animal and their future offspring.  If you don’t believe me google “Missy, the million dollar Holstein” or “Deveronvale Perfection”, a sheep that sold for $376, 691.

I hope you’ll search your area for a State or City Fair.  It’s a great day of entertainment and education, but just remember to wash your hands after touching the animals!
