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.

The Abuja declaration identifies that the prevention and control of HIV/AIDS, tuberculosis and related infectious diseases must come with additional financial resources. Therefore, African governments agreed on setting the target of allocating at l...east 15 per cent of each country’s annual budget to the improvement of the health sector. Moreover, the declaration demands donor countries to assist by fulfilling the target of delivering official development assistance (ODA) in the amount of 0.7 per cent of gross national product (GNP).

Background: Comparable estimates of health spending are crucial for the assessment of health systems and to optimally deploy health resources. The methods used to track health spending continue to evolve, but little is known about the distribution of spending across diseases. We developed improved e...stimates of health spending by source, including development assistance for health, and, for the first time, estimated HIV/AIDS spending on prevention and treatment and by source of funding, for 188 countries.

To better understand the global response to HIV/AIDS, this study tracked
development assistance for HIV/AIDS at a granular, program level.
As the Group of Eight (G8) world leaders meet in Saint Petersburg, Russia for this year’s G8 Summit, it is important to take stock of international efforts to finance the response to the global HIV/AIDS epidemic. Financing a sufficient and sustain...ed response to the epidemic has emerged as one of the world’s greatest challenges, and one that will be with us for the foreseeable future. Often, those countries most affected are also least able to respond, increasing their vulnerability to HIV/AIDS and in turn further complicating their ability to address the epidemic, as is the case for many nations in sub-Saharan Africa. In addition, concerns have been raised about “second wave” nations, particularly China, India, and Russia, which stand on the brink of generalized epidemics if more is not done now

This report provides an analysis of donor government funding to address the HIV response in low- and
middle-income countries in 2022, the latest year available, as well as trends over time. It includes both
bilateral funding from donors and their ...contributions to the Global Fund to Fight AIDS, Tuberculosis and
Malaria (Global Fund), UNITAID, and UNAIDS. Overall, the analysis shows that while donor government
funding for HIV increased between 2021 and 2022, this was primarily due to the timing of payments from
the U.S. government and not actual increases in commitments.

For the global community to be able to achieve ambitious targets relating to the prevention and treatment of HIV, viral hepatitis and sexually transmitted infections (STIs), multiple types of medicines must be widely accessible to all affected popul...ations in all countries.
The purpose of this report is to provide forecasts of future demand for medicines used in the fields of HIV, viral hepatitis and STIs. This report jointly presents medicines forecasts across three disease areas in recognition of the benefits of addressing HIV, viral hepatitis and STIs in a coordinated manner.

The Malawi National Strategic Plan (NSP) for HIV and AIDS 2020–2025 is the guiding document for the multi-sectoral response to the HIV epidemic for the next five years. It succeeds the 2015-2020 <...span class="attribute-to-highlight medbox">HIV NSP, building on previous achievements and addressing areas that need improvement with the goal of meeting 95:95:95 targets and eliminating HIV as a public health threat by 2030. Implementation of the previous NSP contributed to the dramatic decline in the number of new infections from 111,000 in 1992 to 33,000 in 2019 and the decline in AIDS deaths from 71,000 in 2004 to 13,000 in 2019.1 As of September 2019, progress on the 90:90:90 UNAIDS Fast-Track targets was 93:84:92.

This document defines the framework for Malawi’s National HIV Programs. Considering public health benefits and risks, as well as funding and resource implications, deviations from these guidelines are not supported by the Ministry of Health.
In a prospective cohort study in Bangwe primary care clinic, Blantyre, Malawi, all adults (18 years or older) presenting with an acute illness were screened for TB symptoms (cough, fever, night sweats, weight loss). Demographic characteristics were linked to exit interview by fingerprint bioidentifi...cation. Multivariable logistic regression models were constructed to estimate the proportion completing same-visit HIV testing, comparing between those with and without TB symptoms.

Guidelines on care, treatment and support for women living with HIV/AIDS and their children in resource-constrained settings
The main aim of these guidelines is to enable the central units of national TB and HIV/AIDS programmes to support districts to plan, coordinate and implement collaborative TB/HIV activities. These g...uidelines reinforce current medical understanding, that highly active antiretroviral treatment (HAART) has decreased TB incidence of people living with HIV/AIDS. They are comprehensive, giving an overview of the range of activities that could be undertaken in high burden TB/HIV countries or where a rising prevalence of HIV might fuel TB. Activities highlight the need for comprehensive care, prevention and support for adults living with HIV/AIDS. Comprehensive TB and HIV care and prevention rely on full implementation of the DOTS strategy as part of a wide ranging HIV/AIDS care and prevention programme as well as collaborative TB and HIV programme activities.

In the area of nutrition and HIV, children deserve special attention because of their additional needs to ensure growth and development and their dependency on adults for adequate care. It was therefore proposed to first develop guidelines for chil...dren and thereafter consider a similar approach for other specific groups.
The content of these guidelines acknowledges that wasting and undernutrition in HIV-infected children reflect a series of failures within the health system, the home and community and not just a biological process related to virus and host interactions. In trying to protect the nutritional well-being or reverse the undernutrition experienced by infected children, issues of food insecurity, food quantity and quality as well as absorption and digestion of nutrients are considered. Interventions are proposed that are practical and feasible in resource-poor settings and offer a prospect for clinical improvement.
The guidelines do not cover the feeding of infants 0 to 6 months old, because the specialised care in this age group is already addressed in other WHO guidelines and documents.
