December 1, 2022 is the 35th " World AIDS Day ". This year's "World AIDS Day" publicity event is " to fight AIDS , share health ", emphasizing that everyone must participate and work together to fight HIV.
01
HIV official naming time!
In 1981, the United States released a report on HIV case. From then on, humans discovered a new disease. In 1982, AIDS was officially named. In 1985, China discovered the first case of HIV. The process of human beings in fighting HIV is also constantly improving. Today, more than 30 HIV drugs are available.

Progress in fighting HIV in my country
In the past decade, the number of HIV screening laboratories in my country has increased from 17,000 to 49,000, the number of confirmatory laboratories has increased from more than 300 to more than 700, and the designated antiviral treatment institutions have increased from more than 3,400 to more than 6,000; the number of tests increased from 101 million in 2012 to 320 million in 2021; the proportion of antiviral treatment and the proportion of successful treatment increased from 87.3% and 88.7% in 2012 to 92.6% and 96.4% respectively, and the cumulative number of people receiving traditional Chinese medicine treatment increased from 24,000 in 2012 to 64,000 in 2021.
has also made great innovations in HIV detection. "HIV urine anonymous test package " has been piloted in many universities. This is one of the new measures for HIV universities to prevent and control AIDS.

Although we cannot cure HIV now, it has drug control, and countries around the world have also participated in the HIV vaccine competition. I believe that in the near future, vaccines for preventing HIV will be born after people's continuous efforts.

and HIV are just one word different HBV is also terrible
In fact, there is another virus and HIV that are just one word different. The transmission methods of the two viruses are similar, and they may cause hidden transmission in the population, and infected people may not immediately develop the disease and show symptoms. This virus is HBV - hepatitis B virus . Fortunately, this virus has a vaccine to prevent.
Since 1992, my country has included the vaccination of infants and young children with hepatitis B vaccine in the planned immunization management, and by 2005, hepatitis B vaccination has been completely free. At present, with the joint efforts of all people, the positive rate of surface antigen of hepatitis B virus in people under 5 years old in my country has dropped from 9.76% in in 2002 to 0.32% in 2014. However, due to the huge population base in my country, there are still a large number of existing patients.
We all understand that hepatitis B virus is an important murderer in liver cancer . Most cirrhosis and liver cancer develop from hepatitis B.
" Hepatitis B-cirrhosis-hepatitis cancer " is called the "Hepatitis B trilogy".
In general, about 10% to 30% of chronic hepatitis B patients develop cirrhosis after 5 to 10 years, and 5% to 10% of patients with cirrhosis have transformed into liver cancer after 5 to 10 years. Some patients also have cirrhosis and liver cancer simultaneously. Therefore, the hepatitis B vaccine is also called ", the world's first anti-cancer vaccine, ".
However, among the people vaccinated with hepatitis B vaccine, some people still cannot produce enough antibodies after multiple vaccinations. This group of people is called " non-responsive population ". Those who "no response" (hepatitis B two-and-half tests are completely negative or hepatitis B surface antibodies <10mIU/ml)>
60μg hepatitis B vaccine can help non-responders produce effective antibodies. Moreover, it has 3 injections of less than , and 1~2 injections of are required throughout the whole process. It can increase the antibody titer level faster than the low-dose hepatitis B vaccine, allowing the body to quickly obtain immunity to the hepatitis B virus and protect people from the invasion of the hepatitis B virus.
The specific vaccination procedure is as follows:
● people who have no response (after receiving 3 doses of hepatitis B vaccine throughout the whole process, the antibody titer is still less than 10mIU/ml), and 1 to 2 doses of 60μg hepatitis B vaccine can be vaccinated.First, take one shot, and check the surface antibody of hepatitis B two months later. If there is still no response, take the second shot.
● low response population (three doses of hepatitis B vaccine were received throughout the whole process and the antibody titers are now between 10 and 100mIU/ml), and 1 dose of 60μg hepatitis B vaccine was received.
● For those who were immunized with for the first time, and those with unknown immunization history will receive 2 shots of 60μg hepatitis B vaccine according to the procedure from 0 to February.
Although we humans are small in front of viruses, as long as we do not give up on research on viruses, we will eventually defeat them.
