Mycobacterial infection, a common vaginitis infection caused by Candida. There is a relationship with sexual life. However, Candida, as a commensal organism in the human body, may cause disease only under certain conditions. Genital candidiasis is a common disease of the genitalia of both men and women, and the human body itself is a carrier of Candida. Therefore, the infection may be caused by a decrease in the immunity of the body, which leads to the proliferation of Candida and causes the symptoms of vaginitis. It may also be transmitted through sexual life, which is definitely related to the husband. If the former is the case, it is recommended to go to the hospital to improve the relevant examination. Clotrimazole vaginal suppositories and nifurtimycin vaginal soft capsules can be given to treat the mold, and sexual intercourse should be prohibited during the treatment period to prevent the infection to the husband. If the cause is the latter, it is recommended that both parties should receive treatment. At the same time, after the cure, we must actively prevent the reinfection of mold, exercise, enhance the immunity of the body; develop good hygiene habits; prohibit other people’s supplies in public areas; advocate shower, no tub bath; avoid unclean sex; do not abuse antibiotics, etc. Therefore, the emergence of mold infection, both husband and wife should actively improve the relevant examination, and give symptomatic treatment.
