Can genital herpes in women heal by itself?
Genital herpes has an intermittent onset because herpes cannot be said to be cured and never recurs. The herpes virus congregates at the sacral nerve roots in the human body. Therefore, when immunity is low, the virus travels along the sacral nerve root to the surface of the skin, causing damage in spots, commonly known as a recurrence of herpes. Thus, genital herpes does not heal on its own; it is merely in a quiescent phase of an outbreak. Therefore, genital herpes is generally harder to treat in females than in males because the female body has a cavity, and herpes inside the cavity may not be visible.
Can gonorrhea relapse?
Gonorrhea (gonococcus) is caused by a bacterial infection. If it is an initial infection of gonococcus, it can be completely cured using sensitive antibiotics in the prescribed treatment course at a standard hospital. However, if the medication is used irregularly or intermittently by oneself, this can easily lead to drug resistance in gonococcus. Therefore, if drug resistance in gonococcus occurs, the effectiveness of the treatment is relatively poor. Hence, it is crucial to receive treatment at a standard hospital through formal medical procedures. Of course, if it is recurrent gonococcal infection, repeated infections may require a longer treatment course.
Gonorrhea and syphilis symptoms
Gonorrhea infection, if in males, generally presents with significant urethral irritation including symptoms such as urethral discharge, frequent urination, urgent urination, and pain during urination. However, in females with gonorrhea, it may cause increased vaginal discharge and an unusual odor, but many women with gonorrhea do not exhibit any symptoms. As for syphilis, if it is primary syphilis, ulcers may appear on the genitals, lips, or other body parts, known as chancres. In typical secondary syphilis, pinkish-red rashes may appear on the palms of the hands and soles of the feet, usually without itching, although rashes may also occur on the trunk and might not be itchy. Additionally, many cases of syphilis remain latent and show no clear symptoms.
Can genital herpes be completely cured without recurrence?
Genital herpes is difficult to completely cure without recurrence because the virus from the previous herpes outbreak resides at the sacral nerve root. When resistance is low, typically during times such as drinking alcohol and staying up late, the herpes virus travels to the area served by the sacral nerve, such as the external genitals, buttocks, and perineal region, causing blisters. Therefore, it is very difficult to completely eliminate genital herpes so that it never recurs, but the likelihood of recurrence generally decreases significantly after five to six years. Therefore, what we need to do is mainly to enhance our immune function. We can use some medications to help boost immunity, and we should also try to drink less alcohol and get more sleep.
Is blood testing for genital herpes accurate?
Genital herpes testing, blood tests generally reflect antibodies, which have a certain window period. If genital herpes has just occurred, and blisters have just formed, it is very possible that the antibodies are still negative, but the disease has already manifested. Or, the genital herpes may have healed, but the antibodies are positive. Therefore, blood tests can generally only diagnose past infections and are not very accurate for current infections. Thus, the best method for testing genital herpes is to collect blister fluid for DNA testing using PCR methods when blisters are present. This approach is the most accurate, while blood tests can only serve as a reference.
How is genital herpes tested?
Herpes viruses are generally divided into two types, type 1 and type 2 genital herpes, mainly caused by type 2 herpes virus. The best approach for type 2 herpes virus is to use blister fluid for PCR testing of DNA. If testing is not possible, you can also consider blood tests for herpes virus antibodies. If the IGM for type 2 herpes virus is positive, then consider it a current symptomatic infection. If the IGM is negative, but HCG is positive, then consider this herpes as a past infection.
Gonorrhea testing methods
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 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.
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.
Is genital herpes serology accurate?
Serological testing for genital herpes in hospitals generally provides testing for type 1 and type 2 viruses, including IgM and IgG. Over 90% of genital herpes cases are primarily caused by type 2 virus, so the focus is typically on type 2 virus IgG and IgM. However, IgM represents an active infection, meaning a current infection stage. If IgM is negative and IgG is positive, it indicates a past infection. These results are generally accurate, but their timeliness is not as high as DNA's timeliness. Therefore, if possible, it is best to collect vesicle fluid on the first or second day of a herpes outbreak and use PCR to test the DNA for the most accurate results.
