Core Viewpoint - The importance of early detection and treatment in HIV/AIDS prevention is emphasized, as it significantly reduces the risk of opportunistic infections and complications, ultimately lowering the economic burden on patients [1][2]. Group 1: Early Detection and Treatment - Early detection of HIV allows for intervention before the immune system is severely compromised, which can significantly lower the risk of opportunistic infections [1]. - Delaying diagnosis due to misconceptions about false positives or lack of symptoms can lead to missed treatment opportunities and increased health risks [1]. - Effective suppression of viral load through early treatment greatly reduces the risk of HIV transmission, benefiting both the patient and the broader community [1]. Group 2: Prevention Methods - The main transmission routes for HIV include sexual contact, blood exposure, and mother-to-child transmission, with specific preventive measures recommended for each [2]. - Safe sex practices, such as consistent condom use and avoiding multiple sexual partners, are crucial in preventing sexual transmission [2]. - For blood transmission, it is advised to avoid sharing needles and ensure that any blood products are tested; also, procedures like tattooing should be done in regulated environments [2]. - Pregnant women with HIV should receive timely antiviral treatment to prevent mother-to-child transmission, with most able to give birth to healthy babies through proper intervention [2]. - In cases of high-risk behavior, seeking medical attention within 72 hours can help block the virus's replication, serving as a critical last line of defense against transmission [2]. - Common social interactions do not pose a risk for HIV transmission, as the virus does not survive well outside the human body [2].

Core Viewpoint - The event on June 6, 2025, marks the 30th National "Eye Care Day," focusing on public awareness of common eye diseases and their prevention and treatment strategies, particularly in the context of an aging population [1][4]. Group 1: Common Eye Diseases - Cataracts, glaucoma, age-related macular degeneration, presbyopia, and dry eye syndrome are prevalent eye diseases that significantly impact quality of life [1][4]. - Cataracts are linked to natural aging and UV exposure, with sunglasses recommended as a preventive measure [3]. - Glaucoma results from increased intraocular pressure leading to irreversible damage to the optic nerve, often associated with stress and irregular lifestyles [3]. Group 2: Prevention and Treatment Strategies - Preventive measures for glaucoma include self-care, stress management, aerobic exercise, and various treatment options such as medication, laser therapy, and surgery [3]. - Dietary recommendations for age-related macular degeneration include consuming foods rich in lutein, such as carrots and corn, alongside mainstream treatment options like medication and surgery [3]. - Presbyopia, a functional disease due to aging, can be managed with appropriate eyewear, medication, and surgical interventions [3]. Group 3: Public Awareness and Education - There is a need for increased public awareness regarding the scientific understanding of these eye diseases, emphasizing the importance of early detection, intervention, and treatment to prevent irreversible damage [4].
