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.
Pelvic inflammatory disease (PID) is usually caused by a sexually transmitted infection (STI) that infects the cervix . When the cervix, which connects the upper vagina to the uterus, is infected with an STI, other bacteria in the vagina can more easily get into and infect the uterus and fallopian tubes. The most common STIs that cause PID are gonorrhea and chlamydia. PID caused by chlamydia may have milder symptoms or no symptoms (compared with PID caused by gonorrhea), which can delay diagnosis. PID caused by chlamydia is most common among teenagers and young adult women.
