Can the probability of AIDS infection be calculated? AIDS patients have a regular diet.

There is a set of formulas for calculating AIDS infection. Let's take a look at this formula for calculating the probability of AIDS infection.

What is venereal disease? Formula for calculating the probability of HIV infection

HIV infection probability = other party infection probability × behavior infection probability × missed detection probability

Instructions for use:

1. With regard to the infection probability of the other party, if it is determined that the other person is infected with HIV or a patient, it is calculated by 100%. If it is not possible to determine whether the other person is infected, then depending on the situation, there are generally several situations:

①, if the other party is a female sex worker, it can be calculated according to an average of 1% (reports vary from place to place, as high as 5% in some places)

②, if the other person is gay, it can be calculated at 5 per cent. (it has been reported in the UK that the HIV infection rate among gay people in London is as high as 15 per cent. Some experts estimate that the HIV infection rate among gay men in big cities in China may be as high as 5% 15%)

③, if the general population is calculated according to 0.1% (the total population of China is 1.356 billion, by the end of April this year, a total of 203527 cases of HIV infection have been reported in the mainland. In order to facilitate calculation, let's enlarge this data by 6.67 times to 1.356 million, and the population infection rate is 0.1%).

④, if intravenous drug users, can be calculated according to an average of 10% (the infection rate of intravenous drug users is 4.7% in London and 2.3% in the United Kingdom; it is reported online that the infection rate of drug users in Xinjiang, Yunnan, Sichuan and other places in China is more than 50%, while the infection rate of local injecting drug users in Yili, Xinjiang is as high as 89%).

⑤ and the above situations all have regional characteristics. Generally speaking, the percentage of people who come into contact with people in high-incidence areas and those who come into contact with people from high-incidence areas should be appropriately increased according to the local situation.

2. The probability of being infected through the following behaviors (that is, behavioral infection rate). Assuming that the other party has been identified as infected):

①, passive anal sex without condom 0.1-3.0%

②, uncovered active anal intercourse 0.06%

③, passive vaginal intercourse without condom 0.1-0.2%

④, non-condom active vaginal intercourse 0.03-0.09%

⑤, unprotected contact between husband and wife (5 years) 10%

⑥, having sexual intercourse is multiplied by 15% based on the above probability.

⑦, passive oral sex 0-0.04% (in a study of 102 gay and bisexual men newly infected with HIV, the University of California found that eight of them may have had unprotected oral sex. Be careful not to interpret this sentence as the infection rate of oral sex in the population is 8%)

⑧, blood transfusion 90-100%

⑨, mother-to-child transmission 20-30%

⑩, acupuncture 0.3%

3. For complex behaviors or multiple behaviors, the infection probability can be calculated separately and then added up.

4. About the probability of missing detection:

①, if there is no HIV antibody test, it is calculated according to 100%.

One month after ② and high risk, the antibody test was negative. For convenience, the missed detection rate can be calculated according to 1%.

Three months after ③ and high risk, the antibody test is negative, and the missed detection rate can be calculated according to 0.1%.

④, if it is negative after n tests, it can be calculated according to 1% of the n-th power. '

According to this formula, couples or male and female friends who have a stable one-on-one relationship have almost zero chance of contracting AIDS; in China, men who have condom sex with ordinary strange women have a 9/100000000 chance of being infected with AIDS; while non-condom sex with female sex workers is close to 1/1000. Judging from this result, men and women who have normal relationships and have only one partner in China have little chance of being infected with AIDS. Having multiple sexual partners or having sex with a sex worker is very dangerous.

If you are infected with AIDS, you should pay attention to the following dietary plans

What are the dietary care methods for AIDS patients? Here is the reason to tell you.
