One of the most miserable and unpleasant scenarios is getting an infectious diarrhea when camping, hunting or backpacking or any time for that matter. Here are some basic information as well as when it is time to seek out a health care provider.
Diarrhea is a subject matter that most of us will be familiar with at some point in our life. Most of these episodes are self limited. Especially most viral diarrhea which are common in school age children are self limiting and subside in 72 hours.
Diarrhea is uncomfortable and when on a trip and in the outdoors it becomes a very uncomfortable problem. It can be incapacitating and is rarely fatal. Fatalities with infectious diarrhea have to do with comorbidity, dehydration and cardiac arrythymias for the most part.
Infectious diarrhea is caused by food, beverage or waterborne pathogens which are either viruses, bacteria or protozoa parasites. These can cause watery diarrhea, cramping and severe abdominal pain. Foul smelling stool is also common.
Prevention is the first step in limiting one’s exposure to any infectious agent.
Cryptosporidium is a protozoa that also causes infectious diarrhea. It is commonly found in contaminated water. It is characterized by severe watery diarrhea that can be accompanied by low grade fever. In general it is self limiting. And if left untreated usually only last about three days. Outbreaks are common in day care centers.
Symptoms: cramping, nausea, nausea and diarrhea, rare that diarrhea is bloody.
Cryptosporidium is spread by oral contact with contaminated objects or drinking polluted water and eating unwashed vegetables. It also can be contracted by swimming and inadvertently swallowing water.
Myth you cannot get Cryptosporidium from chlorinated water.
Boiling does kill Crypto.
Campylobacter is an infectious bacteria causes severe diarrhea and severe bloody stool. Bloody diarrhea is seen with this bacteria and E-Coli. Unlike Crypto and Giardia Campylobacter also presents as nausea and emesis. The main culprit with this bacteria is eating poultry and eggs but it can be found in other meats. Unpasteurized milk is also a common source. When camping and bringing these food sources please wash them thoroughly and cook them thoroughly. Even if you like your meat rare in a camping situation when far away from treatment it is beneficial to eat your steak well done.
Giardia is thought to be in about 80% of North Americas water source. It has been labeled Beaver Fever however it can come from many sources of wild animals who defecate in streams. Elk, deer, bison, moose, voles and even birds. Patient presents with malodorous diarrhea which can be explosive and watery. It is usually self limiting however treatment is excellent and it can resolve quickly. It should be noted there are some resistant strains to our commonly used antibiotic and I have used an alternative in the last ten years.
