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.

COVID-19 has altered health sector capacity in low-income and middle-income countries (LMICs). Cost data to inform evidence-based priority setting are urgently needed. Consequently, in this paper, we calculate the full economic health sector costs of COVID-19 clinical management in 79 LMICs under di...fferent epidemiological scenarios.

In April 2020, Gavi and COVAX joined the Access to COVID-19 Tools Accelerator (ACT-A) to provide equitable global access to COVID-19 vaccines to tackle the pandemic. In June 2020, the Gavi COVAX Advance Market Commitment (AMC) was launched to finance equitable access in 92 lower-income countries. Si...nce then, US$ 10 billion has been raised for the AMC to procure vaccines and support delivery. Despite a challenging supply situation, COVAX has now shipped one billion doses to 144 countries, including over 870 million to AMC economies.
