Summary
New AIDS cases in Japan are rising despite HAART availability, due to low HIV testing coverage. Enhanced prevention strategies and collaboration are crucial to combat HIV infection.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Context:
- National HIV/AIDS surveillance in Japan began in 1985.
- Highly Active Antiretroviral Therapy (HAART) became widely available in Japan in 1997.
- Despite HAART, a consistent increase in new AIDS patients has been observed.
Purpose:
- To analyze trends in new AIDS cases in Japan.
- To identify factors contributing to the lack of decline in AIDS incidence.
- To highlight the need for improved HIV testing and prevention strategies.
Summary:
- The number of new AIDS patients in Japan has steadily increased since 1985.
- The limited uptake of voluntary HIV counseling and testing (VCT) and the absence of provider-initiated testing and counseling (PITC) are key issues.
- Revised HIV Prevention Guidance in 2005 recommended core hospitals for monitoring, policy evaluation, prevention activities, and enhanced HIV testing.
Impact:
- The findings underscore the critical need to increase HIV testing rates in Japan.
- Collaborative efforts among the public, healthcare workers, NGOs, and government are essential for effective HIV prevention and control.
- Implementing comprehensive strategies is vital to curb the rising trend of HIV infection and AIDS.

01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:22Healthcare Associated Infections II: Preventive Measures
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
