Gonococcus is the pathogenic bacilli of gonorrhea. Gonorrhea is the one of the sexually transmitted diseases (STD), which is the NO. 1 incidence of STD disease in China.
Human-being is the only host for gonococcus. Sex transmitted is the main way to cause the gonorrhea for adults. The reason for little girl’s gonorrhea is indirect transmitting through contacting her parents’ commodities. The physical effect is tumid and pain on outer vagina, erosion, dense secretion on vagina and so on. The new babies get gonococcus conjunctivitis from their gonorrhea mothers’ vagina injection.

Syphilis is an important sexually transmitted disease, which could arise genital apparatus, accessorial lymph and whole physical pathological changes. It is caused by syphilis pain leptospira infection.
Human-beings are the main transmitted source for Syphilis disease. Mainly transmitted way is through unprotected sex. The pregnancy female could transmit the syphilis disease to her baby directly by placenta. The baby’s disease is called pre-exist syphilis.
Syphilis could be divided in to three periods:
  1. Hard chancre could appear on the first period of Syphilis. About one month, this chancre could be cure naturally. During this time, the leptospira would latent in the human body for 2-3 months, and then the second period happens.
  2. All skin surface will see the syphilis anthema, lymph intumesce. These results can also influence the other apparatus: bones, eyes, arthrosis and others. After three years, it could enter the third period.
  3. Syphilis virus not only destroy the skin, but also destroy all the human’s apparatus and structure. After 10-15 years, the serious matter could arise the hear blood vessel and nerve center’s pathological changes.

Human immunodeficiency virus(HIV) is the disease source of acquireding immune deficiency syndrome(AIDS). From its first report in USA in 1981, it threaten human’s health with its high death level, big quantity transmitting and rapid transmitted speed. It becomes a conspicuous disease worldwide.
The infecting way of HIV is infected person and pre-exist HIV person. HIV virus would be analysis through their blood, semen, secration of their vagina, latex, medullary fluid, brains fluid and tears. There is three ways for HIV virus transmitting: A) sex B) pipe or tube for HIV blood transportation and polluted medical equipment by HIV virus. C) Especially the corporate injectors of drug abuse persons’. D) Mother to baby transmitting.

There is only one red line appeared on the strip, which means the HIV antibody in blood is negative. The sample blood has no HIV infection result. People should relax and be in safe situation. But during the beginning 3 months of the HIV virus in human’s body, the positive result would be hard for testing. In this way, we suggest that people should take a test after 6 months when they suspected their infection of HIV.

If the testing time be controlled within 30 mins. There would be no difference between these two ways, because the blood form different parts of the body would show different speed during their climbing on the strip. When the HIV antibody in the serum reaching the testing line and show the red result, the hemoglobin in plasma has not reached the testing section. At this time (within 30mins), the testing result would be no problem. If the time is over 30mins, the hemoglobin with red color could arrive the testing section; it will make some confusion for unprofessional people. But in fact, this is easy to distinguish if you have strip experience. The real red line for testing appearing on the strip would be in cross way. On the other hand comparing with the hemoglobin’s red confusion, its line would be in longitudinal style, from the bottom to the up side.
