Fermo, Italy - Recent assessments indicate a slight decrease in HIV diagnoses across Italy, but health officials emphasize the ongoing risk of infection, particularly among young adults. Dr. Alberto Licci, medical manager of the infectious diseases department at the Murri hospital in Fermo, highlights the importance of continued prevention efforts and early detection.
What is HIV and AIDS?
HIV, or Human immunodeficiency Virus, is a virus that attacks the body’s immune system. It progresses slowly, often without noticeable symptoms for years, targeting the body’s defenses against other infections.When the virus severely weakens the immune system, it leads to AIDS, or Acquired Immunodeficiency Syndrome, characterized by a range of opportunistic infections and conditions [[1]].
The virus can also cause hematological alterations, potentially leading to leukemia.
HIV Statistics in Italy and the Marche Region
Over the past decade, new HIV diagnoses in Italy have modestly declined, now averaging between four and six cases per 100,000 people annually. AIDS diagnoses have also decreased, falling below one case per 100,000 people per year. However,officials caution against complacency,emphasizing the importance of timely diagnosis and treatment.
The Marche region mirrors this national trend, with approximately two to four new HIV diagnoses and fewer than one new AIDS diagnosis per 100,000 people each year.
| Region | New HIV Diagnoses (per 100,000) | New AIDS Diagnoses (per 100,000) |
|---|---|---|
| Italy (National) | 4-6 | <1 |
| Marche Region | 2-4 | <1 |
Rising Incidence among Young Adults
New HIV diagnoses are relatively higher among individuals aged 16 to 35,reaching 4.5 to 6.2 cases per 100,000 people per year. A significant majority – approximately 75% – of these diagnoses are in males. Though, when considering only heterosexual transmission, the proportion of new diagnoses in females rises to 35%, compared to 65% in males.
Did You Know? Antiretroviral therapy (ART) not only improves the health and lifespan of people living with HIV but also prevents onward transmission of the virus [[2]].
Factors Contributing to Infections in Youth
The increased frequency of infections in young people is attributed to insufficient details regarding prevention and care, coupled with inconsistent awareness initiatives across different regions. Improved collaboration between the healthcare system and schools is crucial to address this issue.
Transmission Routes of HIV
Today,HIV is primarily transmitted through sexual contact,with heterosexual transmission being the most common route. Male-to-male sexual contact remains a significant mode of transmission, particularly due to the increased risk of trauma in the anal area.Transmission through intravenous drug use, while declining, remains an significant factor.
Late Diagnosis and its Consequences
Delays in HIV diagnosis are often linked to a lack of awareness about testing options and lingering stigma surrounding the disease. Early diagnosis and treatment are critical to preventing disease progression and improving health outcomes.
Pro Tip: Regular HIV testing is recommended, especially for individuals with multiple partners or those engaging in high-risk behaviors.
Mortality Rates and Therapeutic Advancements
Approximately 500 people in Italy and fewer than 20 in the Marche region die annually from AIDS-related complications, deaths that could be avoided with earlier diagnosis and treatment. Significant advancements in antiviral therapy since the late 1980s have dramatically improved the outlook for people living with HIV.
Current treatment regimens often involve a single daily tablet that suppresses the virus to undetectable levels, preventing transmission and restoring immune function. Long-acting injectable therapies are also available, improving quality of life for many patients.
Specific Risk Factors: Chemsex and Penitentiary Institutions
“Chemsex,” the use of psychoactive substances to enhance sexual experiences,is emerging as a risk factor for HIV transmission due to increased risk-taking behaviors and potential for addiction. HIV prevalence is also higher in penitentiary institutions due to the concentration of marginalized populations, intravenous drug use, and limited access to healthcare and education.
Prevention Strategies
Effective prevention strategies include consistent condom use, pre-exposure prophylaxis (PrEP) for individuals at high risk, and post-exposure prophylaxis (PEP) following potential exposure. Regular HIV testing is also essential.
What are your thoughts on the availability and accessibility of PrEP in your community? do you believe more education is needed regarding HIV prevention?
The Search for an HIV Vaccine
Despite over four decades of research, a vaccine to prevent HIV infection remains elusive. While significant progress has been made in understanding the virus, funding for vaccine research has faced setbacks in some regions, hindering progress.
The global fight against HIV/AIDS has seen remarkable progress, with a significant reduction in new infections and AIDS-related deaths since the peak of the epidemic in the mid-1990s. However,challenges remain,including addressing disparities in access to treatment and prevention services,combating stigma,and developing a cure. Ongoing research focuses on innovative prevention strategies, such as long-acting injectable PrEP and therapeutic vaccines, as well as efforts to eliminate the epidemic in key populations and geographic areas.
Frequently Asked Questions about HIV
- What is HIV? HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, leading to AIDS if left untreated.
- How is HIV transmitted? HIV is primarily transmitted through sexual contact, sharing needles, and from mother to child during pregnancy, childbirth, or breastfeeding.
- Can HIV be prevented? Yes,through consistent condom use,PrEP,PEP,and regular testing.
- is there a cure for HIV? Currently, there is no cure for HIV, but effective treatments can manage the virus and prevent transmission.
- What are the symptoms of HIV? Early symptoms can be flu-like, but many people experience no symptoms for years.
