HIV & AIDS Treatment in Practice No. 188
Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

Recommendations for a public health approach
2010 revision
Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people ...living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5–15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV

Provide guidance to HIV care practitioners on the optimal use of antiretroviral (ARV) agents for the treatment of HIV infection in adults and adolescents.
MSF provides treatment for HIV and tuberculosis (TB) in more than 20 countries around the world. The report Burden sharing or burden shifting? How the HIV/TB response is being derailed examines the situation in nine countries where MSF runs programmes: Central African Republic, Democratic Republic ...of Congo, Eswatini, Guinea, Kenya, Malawi, Mozambique, Myanmar and Zimbabwe. With a focus on the financial resources available, this report highlights the current risks and gaps in HIV and TB service delivery in these countries.
Given the findings of gaps in diagnosis, prevention and care services and dwindling resources, MSF calls for a robust assessment of the needs and the resource capacity of each affected country, and calls on international donors to ensure that the financial burden is shared, rather than shifted onto those countries worst affected by the diseases.

Policy Brief

July 2021. This publication brings together important clinical and programmatic updates produced by WHO since 2016 and provides comprehensive, evidence-informed recommendations and good practice statements within a public health, rights-based and person-centred approach.
These guidelines bring in... the most recent guidance on HIV testing strategies - the entry point for HIV prevention and treatment - and include comprehensive guidance on infant diagnosis. Key recommendations are presented on rapid antiretroviral therapy (ART) initiation and the use of dolutegravir. Updated recommendations are included on the timing of ART for people with TB, and the use of point-of-care technologies for treatment monitoring.
