Stomach Flu Contagious Causative Agents

The catch here is, are all medical conditions with the word flu in its name are really influenza? The answer is a big NO! Take for example stomach flu illness also otherwise known as gastric flu or intestinal flu, it is medically referred to as gastroenteritis yet it is not categorically an influenza or flu although with in cases with virus as a causative agent there is presence of inflammatory cells due to inflammation of the stomach, small intestine and to some extent includes inflammation of the large intestine as well which might cause possible temperature elevation as a normal defense reaction of the human body.

What is a Stomach Flu?  

It is important to note that the suffix “itis” usually indicates inflammation. Any medical condition with “itis” affixed at the end of the root word usually indicates inflammatory condition such as gastroenteritis or what is popularly known in layman’s term as the contagious stomach flu. Gastroenteritis is a medical health condition wherein there is presence of stomach and intestinal irritation as well as inflammation or to a greater extent inflammation of the entire gastrointestinal tract.

Is Stomach Flu Contagious?

Clinically, contagious refers to the capability of passing a condition via direct physical contact with an infected individual or contaminated food, clothing or any object which have direct contact with the causative factor. The mode of transmission for stomach flu is via oral-fecal route often acquired from contaminated water and poor hygiene and sanitation regarding food preparation.

Causative Agents of Stomach Flu Contagious

Viral Induced Gastroenteritis

According to medical research stomach flu contagious norovirus caused approximately 50% of the cases of contamination from ill preparation of food. The 20% is caused by rotavirus and the affected majority are kids.  The 30% is caused by either of the two.  

Bacterial Induced Gastroenteritis

The common causing bacteria are the following: salmonella, shigella, staphylococcus, campylobacter jejuni, clostridium, eschirichia coli, yersinia, vibrio cholera. Each bacterium causes more or less similar physical manifestations with a common symptom of diarrhea. Sometimes colitis or inflamed large intestine is observed.

Parasite Induced Gastroenteritis

Parasites such as giaradia and cryptosporidium can induce severe stomach flu persisting for weeks. For giaradia the brooding period is often 1-2 weeks and for cryptosporidium it’s 2-10 days. Both of which originated from stools. However, water contamination by parasite infected stool is the common causative factor. It is imperative especially kids to be reminded always to close mouths when engaged in water recreation as one gulp of contaminated water poses a great health risk. Food contamination is a possible cause as well. It is important to bear in mind that the chemical agent chlorine commonly used for water treatment cannot eradicate cryptosporidium.

Trichinella parasite contaminates not well cooked or raw foods especially meat dishes. It may cause symptoms which run for 1-2 days from onset such as puking, loose bowel movement and pain in the abdomen sometimes to a greater extent puffiness of the eyes and muscular pain lasting for weeks.
