“…The findings were conveyed in a variety of formats including letters, editorials, expert opinion, reports, webinars, feature articles, news articles, and traditional research articles. In terms of countries, the included articles were from Portugal [ 28 ], Ethiopia [ 29 ], Japan [ 30 ], China [ 9 ], Malawi [ 31 ], the United States of America [ 32 ], Pakistan [ 33 , 34 ], Nigeria [ 35 , 36 , 37 ], India [ 38 , 39 , 40 ], South Africa [ 41 , 42 , 43 ], one provided recommendations for high burdened settings [ 44 ], one presented evidence from LMIC [ 45 ], and one study was addressed to all the countries [ 46 ]. The primary healthcare settings ranged from clinics, outpatient departments, general practitioner’s practices, PHC centers, and pharmacies.…”

“…TB clinics in New York, USA temporarily halted the performance of any new TB tests [ 32 ]. A study from a LMIC reported that fewer TB cases were diagnosed due to the difficulty in accessing primary care [ 45 ], while a clinic in Nigeria reported that one person came to collect the TB medication during the lockdown [ 37 ]. South Africa experienced a 25% drop in access to primary healthcare following the lockdown, as well as a 9% drop in TB testing [ 41 ].…”

Evidence of TB Services at Primary Healthcare Level during COVID-19: A Scoping Review

et al. 2021

Tuberculosis (TB) is still a major public health concern, despite the availability of preventative and curative therapies. Significant progress has been made in the past decade towards its control. However, the emergence of the novel coronavirus disease 2019 (COVID-19) has disrupted numerous essential health services, including those for TB. This scoping review maps the available evidence on TB services at the primary healthcare (PHC) level during the COVID-19 period. A comprehensive literature search was conducted in PubMed, Web of Science, Medline OVID, Medline EBSCO, and Scopus. A total of 820 articles were retrieved from the databases and 21 met the eligibility criteria and were used for data extraction. The emerging themes were the effect of the COVID-19 pandemic on TB services, patient and provider experiences, recommendations for TB services during the COVID-19 period, and the implementation of the recommendations. The review found that the mitigation strategies, as well as fear and stigma experienced at the start of the COVID-19 pandemic may have led to TB cases potentially going undetected, which may threaten TB treatment outcomes. Therefore, efforts must be directed at finding these missing cases and ensuring that PHC facilities are equipped to adequately diagnose and treat them.

“…One of the possible post-pandemic effects is the increase in morbidity and mortality from TB and RR/MDR/XDR-TB due to overcrowded conditions, treatment abandonment and lack of an active search for cases during confinement and outbreaks of COVID-19, allowing the appearance of new outbreaks and chains of transmission, especially in vulnerable populations; thus, measures should be taken and TB control programs should be evaluated and implemented (Buonsenso et al, 2021;Comella-del-Barrio et al, 2020). TB control requires surveillance interventions, clinical assessment, diagnostic testing, contact tracing, and confirmation of diagnosis with supervised treatment regimens; as all these important actions have been limited, all the recent advances in the End TB Strategy have been affected (Homolka et al, 2020;McQuaid et al, 2020;Motta et al, 2020).…”

Molecular genotyping of Mycobacterium tuberculosis allows for the identification of circulating lineages and sublineages in the population and their relationship with migratory movements. The purpose of this review is to describe the phylogeography of Mycobacterium tuberculosis reported in South American countries that was analyzed using genotyping tools, analyze the Tuberculosis hotspots for the region and determine the impact of the COVID-19 pandemic on the Tuberculosis control program. The Latin American Mediterranean (LAM) sublineage belonging to the Euro-American lineage (Lineage 4) presents the highest prevalence in South America and is followed by the Beijing sublineage belonging to the East Asian lineage (Lineage 2). The Beijing sublineage is considered of worldwide interest because of its association with multidrug-resistant tuberculosis (MDR-TB), which is almost entirely distributed in South America, with Peru being the country with the highest prevalence for this sublineage. On the other hand, the Indo-Oceanic (Lineage 1), India-East Asia (Lineage 3) and West- African 2 (Lineage 6) sublineages have been reported with lower prevalence in South America. The molecular techniques used in the genotyping studies for Mycobacterium tuberculosis in South America were as follows: typing by complementary oligonucleotide spacer sequences (Spoligotyping), restriction-hybridization patterns (IS6110-RFLP, PGRS-RFLP), mycobacterial interspaced repeat units-variable number tandem repeats (MIRU-VNTR) and whole genome sequencing (WGS). At present, Brazil and Peru are the hotspots for tuberculosis and MDR-TB in South America, where the control of tuberculosis wholly affected by the COVID-19 pandemic. Thus, there have been significant impacts on containment programs and possible post-pandemic scenarios such that scientific contributions will need to be evaluated and implemented with new strategies for prevention, diagnosis, treatment and control of Tuberculosis.
