Giardia Gastro reported

Postby dazintaz » Wed 02 May, 2018 9:49 pm

Just reporting 7 of our walking group who completed the OT last week have all fallen ill this week from drinking water from tanks. Please exercise caution and boil water before drinking if you intend walking over the coming weeks or until any significant rainfall.

Have they been tested and diagnosed as having giardia or is it just gastro? Giardia is different from gastro and would be a far more serious issue.
Nothing to see here.

Its no coincidence, we are now in 3 different states VIC NSW and TAS and its 7 days after completing the walk and all experiencing the symptoms of a Giardia infection. Lots of people on the track, lack of rain (1 empty tank at Bert Nichol hut) we didn't boil water before drinking. 2 of us have been to the doc today. Not good.

Doesn't sound good at all and no it isn't nice.
But Gastro can be contagious, and Giardia is a far more serious health issue than normal gastro. Get your doctor to take a stool sample done to be sure. Giardia can stay in your system for months and months where gastro will clear within a week.

On receipt of a positive Giardia stool sample test, I would highly recommend contacting Parks Tasmania.

They’d like to know so they can provide info to departing walkers, and treat the water tanks chemically.

Can we be sure the culprit is the tank water and not the usual contamination from handling taps, toilet doors and the like?

Surely you wouldn’t find a group of seven people where they ALL don’t wash their hands before eating?

Dunno.

But the problem (Giardia or gastro) and the source (tanks/other water source/hygiene/food) need to be confirmed before trying to decontaminate the tanks.

Wow, late April and dry tanks.. thirsty bunch

Adult gastro has fast onset/ short incubation, catch from another then from each other even. If the symptoms have now been lingering longer- definitely- get to a doc.

Agreed. That’s why I said this:

On receipt of a positive Giardia stool sample test


Parks may even be able to shed some light on it if others who were on the track have also been diligent enough to report it to them.

I don’t normally treat tank water, but the one time I did was an exceptionally dry and hot spell on the OLT where the levels were getting low - and the water that was remaining was noticeably warmer.

Hope you improve soon Daz!

Correlation does not equal causation.

Giardia is found on surfaces or in soil, food, or water that has been contaminated with feces from infected humans or animals.

It could be the water tanks, or it could just be the general state of the huts and facilities.

I've observed some pretty messy situations on the track and have no doubt how easy it is for a sick person rushing back and forth to the toilet to unintentionally contaminate everything.

A friend was diagnosed with Giardia after a trip to the Southern Ranges a couple of years ago. He most likely picked it up from the long drop toilet at the Cockle Creek ranger station when partaking in a pre-trip poop.

I praise people who putting out Giardia warnings. It is the most horrible parasite. Last year a group of us fell ill for months after drinking from the tanks in Darlington at Maria Island. Water from most tanks and running streams is often safe but all it takes is one bug.

What was the outcome? Giardia or Gastro?

take a look at the intake mesh on top of most of the tanks and see all the possum poo trapped in there.. the water flows right over and through it.. we filtered water EVERYWHERE on the OLT.. takes 2 mins to do a few liters through the Sawyer.. I don't like the taste of possum poo :)

Some of the older huts have tanks attached and getting on the roof presents an easier path to possums.

This one is a reportable disease. I expect if it was in fact giardia, we'd know by now. So too from the many thousands of non- filterers of the past.
It's obviously a very rare set of conditions and happenstance, an infection in Tassie mtns.

(as I understand, bringing water to the boil is enough to kill Giardia parasites)
