What is the most common cause for infection pancreatitis?

Answer 1

The most common infectious causes are mumps, viral hepatitis, coxsackieviruses, echoviruses, and mycoplasma.

How often these pathogens are implicated in the development of pancreatitis is unclear.

Answer 2

There are several possible causes of pancreatitis:

Disease of the biliary tract. The biliary tract is the system of organs and ducts (including the liver, gallbladder, and bile ducts) that creates, transports, stores, and releases bile into the duodenum for digestion. The formation of stones in the biliary tract can block the main duct of the pancreas as it enters the duodenum.
Heavy alcohol use over a long period of time, which can raise protein levels in pancreatic juices. Over time, the protein can form plugs, blocking small pancreatic ducts. Alcohol also allows enzymes to pass more easily through duct walls and damage the pancreas. Biliary tract stones and alcoholism are the most common causes of pancreatitis.
The drugs azathioprine, sulfonamides, corticosteroids, nonsteroidal anti-inflammatories (NSAIDs), and tetracyclines
Infection with mumps, hepatitis virus, rubella, Epstein-Barr virus (the cause of mononucleosis), and cytomegalovirus
Abnormalities in the structure of the pancreas or the pancreatic or bile ducts, including pancreatic cancer
High levels of triglycerides (fats) in the blood
Surgery to the abdomen, heart, or lungs that temporarily cuts off blood supply to the pancreas, damaging tissue
Injury resulting in compression of the pancreas against the spine
Who's Most At Risk?

These conditions or characteristics increase the risk for pancreatitis:

Biliary tract disease
Binge alcohol use and chronic alcoholism
Recent surgery
Family history of high triglycerides
Age (most common between ages 35 and 64)
African-Americans are at higher risk than Caucasians and Native Americans.
