The best place to inquiry about boat passages , problems etc. is the cruise line itself. Unfortunately from time to time , they are less candid with advice. They want to retain your money paid for the trip. Note - winter cruises - the Danube sees limited or non exsistant cruises in winter.
Pelvic inflammatory disease (PID) is an infection caused by bacteria. When bacteria from the vagina or cervix travel to your womb, fallopian tubes, or ovaries they can cause an infection. Most of the time, PID is caused by bacteria from chlamydia and gonorrhea.
Most cases of pelvic inflammatory disease are caused by gonorrhea and/or Chlamydia, although several different types of bacteria can be responsible. Young, sexually active women with multiple sex partners are at greatest risk for pelvic inflammatory disease. Douching and a history of PID are other risk factors.
