The methods for detecting gonorrhea generally fall into two main categories. One involves testing for the pathogen of gonorrhea. A simple method is the microscopic examination of Neisseria gonorrhoeae, which can be seen under a microscope as Gram-negative diplococci. Another method is the cultivation of Neisseria gonorrhoeae, although culturing with medication can occasionally result in false negatives. A more advanced and accurate method is PCR (Polymerase Chain Reaction), which involves using a urethral swab to detect the DNA of Neisseria gonorrhoeae. Currently, this is considered the most sensitive and accurate method available.

Can gonorrhea be transmitted through a washing machine?

The probability of transmitting gonorrhea through a washing machine is very low, but it is still recommended to wash separately for safety. Gonorrhea is mainly transmitted through sexual contact, with patients of the disease being the source of infection. In a few cases, it can also be transmitted through contact with secretions containing gonococci, or through contaminated items such as clothing, bedding, towels, bathtubs, and toilets. Gonococci do not grow well outside the human body and have poor resistance to physical and chemical factors. They can survive for 15 minutes at 42°C, only 5 minutes at 52°C, and die within 1 minute at 60°C. In completely dry environments, they die within 1-2 hours, but in not completely dry environments, and in solutions, they can maintain infectivity for more than ten hours, or even several days. However, gonococci are very sensitive to common disinfectants. If sharing a washing machine, you can add hot water or a disinfectant for washing.

Can gonorrhea cause blood in urine?

Gonorrhea infection can present with symptoms of blood in the urine. Common symptoms of gonorrhea include urethral discharge, a large amount of purulent secretion on the underwear, as well as frequent urination, urgency, and pain during urination. Blood in the urine can also occur, although it is less common. Besides gonorrhea, stones must also be ruled out if blood in the urine is observed. If there is only blood in the urine, the likelihood of it being gonorrhea is relatively small, as gonorrhea usually presents with other accompanying symptoms such as frequent urination, urgency, pain during urination, and itching in the urethra.

The discharge from gonorrhea is what color?

Gonorrhea is a sexually transmitted disease caused by the infection of Neisseria gonorrhoeae, also known as gonococcus, primarily manifesting as purulent infections of the urinary and reproductive organs. The main route of transmission for gonorrhea is through sexual contact, but it can also be transmitted through close living contact and from mother to child. The clinical symptoms of gonorrhea vary; symptoms in males are typically more pronounced, including frequent urination, urgent urination, painful urination, and redness and swelling at the urinary opening, which may exude yellow purulent discharge. In females, the symptoms of gonorrhea are generally milder, commonly affecting the cervix and vagina with mucous secretions initially, which may later become purulent, often without significant noticeable symptoms.

Is urethritis gonorrhea?

Urethritis is not necessarily gonorrhea. Gonorrhea is a sexually transmitted disease primarily characterized by pus-forming infections of the urinary and reproductive systems caused by Neisseria gonorrhoeae. Acute urethritis can be divided into bacterial urethritis, gonococcal urethritis, and non-gonococcal urethritis, which are a broad category of diseases. Therefore, gonorrhea can have the clinical symptoms of acute urethritis and is a type of acute urethritis. If it is gonococcal urethritis, it should be treated as such, while non-specific urethritis should be treated as non-specific urethritis.

What should you avoid eating if you have gonorrhea?

Actually, the dietary restrictions for gonorrhea are not very special and are quite similar to those of general diseases. For gonorrhea, one should not drink alcohol, try to avoid staying up late, and avoid overly spicy and stimulating foods, such as extremely spicy dishes, hot pots, and fried foods. The diet should be as bland as possible. Of course, if we consider one's own resistance, it is possible to make some soup and eat some good chicken soup, which can also improve one's resistance.
