These two groups must arouse attention!

——The proportion of patients aged 50 and above has risen

  According to data from an article published earlier by the China Center for Disease Control and Prevention, among the newly reported HIV infections and patients in my country each year, the proportion of patients aged 50 and above has risen significantly, from 22% 10 years ago in 2011. 44% by 2020.

  At the same time, comparing several provinces where the AIDS epidemic first began, among the newly reported HIV infections and patients in 2020, the provinces with the highest proportion of patients aged 50 and above accounted for more than 60%.

  These data suggest that the situation of middle-aged and elderly people infected with AIDS in recent years is not optimistic, and it has gradually attracted the attention of relevant departments.

  According to the article, from the perspective of the increasing risk of HIV infection among the elderly, attention should be paid to the emotional life of the elderly, so that family and relatives can alleviate loneliness, so that the elderly will no longer blindly seek stimulation and put themselves at risk.

At the same time, it is necessary to promote safer sex behaviors for the elderly to avoid AIDS to the greatest extent.

How much do you know about AIDS?

——What is the difference between people living with HIV and AIDS patients?

  HIV-infected persons: from HIV invades the human body, through the asymptomatic infection period (also known as the incubation period), to the stage before the development of AIDS, called HIV infection (HIV infection), the infected person is HIV-infected (HIV infection). By).

  AIDS patients: After being infected with HIV, after a period of time, the condition has developed to the onset stage, and AIDS-related indicated diseases appear.


the spread of AIDS, which has several?

  HIV is transmitted through three ways: blood, sexual contact, and mother-to-child transmission.

——What are the stages of the development of AIDS?

  The acute infection period (2-4 weeks after being infected with AIDS) can be manifested as low-grade fever, skin rash, lymphadenopathy, etc., but because there are no specific symptoms or signs, it is often ignored.

  The asymptomatic infection period (the incubation period is generally 8-10 years, but the incubation period of some virus strains that have been circulating in my country in recent years has been significantly shortened). There are no symptoms, and the patient can work and live normally.

  During the AIDS period, the virus replicates in the body for a long time, and CD4 cells gradually decline, leading to various opportunistic infections and tumors in the human body.

after infection with HIV, what are the specific symptoms do?

  After being infected with HIV, about 50% of infected people will have fever, diarrhea and other symptoms similar to colds and gastrointestinal infections in the acute stage. There are no specific symptoms, so they will be ignored or treated as colds.

  Some netizens are concerned about the symptoms or signs of body itching, red spots, white spots on the lips, dark spots, acne, and watery stools, but they are not the basis for judging whether they are infected with AIDS.

  If you have related health concerns, it is recommended to immediately seek AIDS counseling and testing services at local CDCs, hospitals and other institutions.

-Can AIDS be completely cured?

  There is currently no cure for AIDS.

However, antiviral therapy can be used to control the development of the disease and improve the quality of life.

  After HIV enters the human body, it will form a virus reservoir in the body, such as lurking in the brain, bone marrow cells, testis, intestinal lymph node cells, and the antiviral drugs we are currently using in the clinic are difficult to clear the virus in the reservoir. .

  However, the current antiretroviral drugs for AIDS can well help the infected person to control their condition. The important thing is early detection, early detection and early treatment to prolong life and improve the quality of life.
