HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti...ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

The National Guidelines for HIV-1 Viral Load Laboratory Testing support plans to scale up viral load (VL) testing to reach the 90-90-90 targets in India. This phased scale-up includes the setup of 70 additional VL testing laboratories nationally. These guidelines include laboratory design considerat...ions, a summary of VL technologies, and specimen collection and handling as well as transportation and storage guidance. Quality control and quality assurance requirements are described as well as laboratory safety issues. The guidelines also describe the VL laboratory network to be developed with supply chain management issues and commodities described. Annexes include laboratory registers and reporting forms.

Trachoma is the leading infectious cause of blindness worldwide. In April 2023, it was a public health problem
in approximately 40 countries, with an estimated 116 million people at risk and 1.5 million people affected
by the late blinding stage of the disease (1). About 84% of those at risk of tr...achoma are in the World Health
Organization (WHO)’s African Region; about 52% of those at risk of trachoma live in Ethiopia

The Integrated Management of Adolescent/Adult Illness (IMAI) approach
Myth: It’s better to ‘tough it out’ without taking asthma medication. The lungs do not get stronger or become better able to deal with asthma if a person tries to work through an attack without medication. In fact, the lung inflammation that goes along with an attack (see what is asthma) ...can cause permanent damage to the lungs. Always use medication according to the Asthma Action Plan. If you have questions, talk with your health care provider.

In many low- and middle-income countries, there is a wide gap between evidencebased recommendations and current practice. Treatment of major CVD risk factors remains suboptimal, and only a minority of patients who are treated reach their target levels for blood pressure, blood sugar and blood choles...terol.
In other areas, overtreatment can occur with the use of non-evidence-based
protocols. The aim of using standard treatment protocols is to improve the quality
of clinical care, reduce clinical variability and simplify the treatment options,
particularly in primary health care. Standard treatment protocols can be developed by preparing new national treatment guidelines or by adapting or adopting international guidelines.
The Evidence-based protocols module uses hypertension and diabetes screening
and treatment as an entry point to control cardiovascular risk factors, prevent target organ damage, and reduce premature morbidity and mortality. A comprehensive risk- based approach for integrated management of hypertension, diabetes, and high cholesterol is included in the Risk-based CVD management module.
This module includes clinical practice points and sample protocols for:
1. hypertension detection and treatment
2. type 2 diabetes detection and treatment
3. identifying basic emergencies – care and referral.
HEARTS emphasizes adaptation, dissemination, and use of a standardized set of
simple clinical-management protocols, which should be drug- and dose-specific,
and include a core set of medications. The simpler the protocols and management tools, the more likely they are to be used correctly, and the higher the likelihood that a programme will achieve its goals.
