Is It Possible to Transmit HIV through Saliva?

Oral mucosal exudate rapid detection reagent ^[1] uses artificially synthesized protein as an antigen to quickly and qualitatively detect HIV1 / 2 antibody in oral mucosal exudate. Because saliva does not transmit AIDS, no wound is detected, and no blood is seen (there is a large amount of HIV in the blood, and the risk of transmitting AIDS is extremely high), so there will be no "contagion", and the risk of infection by the tester or medical staff can be avoided , Occupational exposure risk of sampling personnel, contamination risk of medical waste, etc. ^[1]

AIDS is not transmitted through saliva, but can be tested by oral mucosal exudate ^[2]

On November 7, 2002, the U.S. government-approved rapid test kit required only one drop of blood to detect whether an examinee was infected with HIV within 20 minutes. On March 26, 2004, the Bush administration has approved oral mucosal exudate ^[3]

definition

After HIV enters the body, it takes a period of time before HIV antibodies are produced in the body. During this period, the antibody test is negative. This period is the window period. The amount of HIV in the infected person will reach a peak at this time, which is extremely contagious, and the acute infection period also occurs during this period.

cycle

According to the latest research results on clinical viruses of the highest HIV / AIDS prevention agency in China, the AIDS Prevention and Control Center of the Ministry of Health, the window period is 2-6 weeks.

Window calculation

The calculation of the window period should start at the time of high-risk behavior or when receiving blood transfusion, that is, if high-risk sexual behavior or blood transfusion occurs on January 1, then the time for antibody testing should be from January 1. After 6 weeks, that is February 12.

No blood collection and painless

The oral mucosal exudate ^[3] can be used to detect HIV, avoid blood collection, reduce the pain and discomfort of the subject, and reduce the fear caused by blood collection.

easy to use

Oral mucosal exudate ^{[3] is} easy to detect and sample. Simply place the oral swab in the mouth and wipe it back and forth along the upper and lower gum lines to obtain a sample.

Simple operation (5 photos)

The entire testing process is usually completed within half an hour. There is no need to hire professional doctors or laboratory technicians, and ordinary personnel can operate by themselves after simple training.

Oral mucosal exudate ^{[3] is} easy to interpret. Judging by the number of intuitive lines, the test result is negative or positive.

A. If there are two lines, one in the detection area and one in the control area, the test result is considered positive regardless of sharpness. A positive result indicates the presence of anti-HIV-1 or HIV-2 antibodies in the sample. (Note: If two lines are present, the test result is considered positive regardless of sharpness.)

B. If only one line appears in the control area, the result is negative, indicating that no anti-HIV-1 or HIV-2 antibodies were found in the sample.

C. If the control line in the control area does not appear, the test result is invalid. Even if a detection line appears in the detection area, the test results are still invalid. Invalid tests should be repeated with new test strips or samples.

Avoid infection and occupational exposure

Oral mucosal exudate ^[3] tests can reduce the incidence of blood infectious diseases. The use of auxiliary materials (blood collection needles, etc.) or accidental acupuncture is avoided, and medical personnel are prevented from contracting AIDS due to work while testing patients. The saliva test avoids the generation of pollutants such as biological waste to avoid infection.

Accuracy of oral mucosal exudate detection

At present, the accuracy of AIDS test for oral mucosal exudate is similar to blood test for AIDS products. Generally speaking, the sensitivity is 99.3%, the specificity is 99.9%, and the accuracy is 99.8%.
