It is possible for a man to contract Escherichia coli (E. coli) from a woman. Certain strains of this common bacterium can cause illness when transferred between individuals.
About E. coli
Escherichia coli (E. coli) is a type of bacteria commonly found in the intestines of humans and animals. Most E. coli strains are harmless and are a normal part of the gut microbiota, even aiding in digestion. However, some strains are pathogenic, causing illness if they enter other body parts or if a virulent strain is ingested. These pathogenic strains can lead to infections in the gastrointestinal tract, urinary tract, and other areas.
Pathways for E. coli Transfer to Men
Sexual activity is a notable pathway for E. coli transmission from a woman to a man. During sexual contact, E. coli from the anal or vaginal area can transfer to a man’s urethra, potentially leading to a urinary tract infection (UTI).
Poor hygiene practices also significantly contribute. Inadequate handwashing after using the restroom can spread fecal bacteria, contaminating hands, surfaces, or objects. Research indicates E. coli is more likely to spread through poor toilet hygiene than through contaminated food.
Indirect contact also plays a role. E. coli can survive for short periods on contaminated surfaces or shared personal items. Touching contaminated items and then one’s mouth or genital area can lead to infection. Studies show that E. coli strains causing UTIs can be shared between sexual partners, indicating male UTIs are sometimes sexually transmitted.
Common E. coli Symptoms in Men
Symptoms of an E. coli UTI in men can include a strong, persistent urge to urinate and a burning sensation during urination. Men may also experience frequent urination with little volume, cloudy or foul-smelling urine, and discomfort or pressure in the genital area or lower abdomen.
In some instances, the infection can spread, leading to pain in the back or side, particularly if the kidneys become involved. While less common than UTIs, gastrointestinal symptoms such as diarrhea, abdominal cramps, nausea, and vomiting can also occur, especially if E. coli is ingested. These symptoms typically appear within 1 to 10 days after exposure.
Prevention and When to Seek Medical Care
Preventing E. coli transmission involves consistent hygiene practices. Thorough handwashing with soap and water is important, especially after using the restroom, before preparing food, and after contact with animals. Practicing safe sexual behaviors, such as proper hygiene before and after sexual activity, can help reduce the risk of transfer.
Seek medical care if E. coli symptoms develop or worsen. Consult a healthcare provider if you experience diarrhea lasting more than a few days, bloody diarrhea, a fever higher than 102°F, persistent pain during urination, severe abdominal pain, or signs of dehydration like dizziness or reduced urination. Prompt diagnosis and appropriate treatment prevent potential complications.
