Background: Annual mass drug administrations (MDA) of ivermectin will strongly reduce Onchocerca volvulus microfilariae (mf) in the skin and in the onchocerciasis patients' eyes. Ivermectin treatment will also affect the expression of immunity in patients, such that activated immune defenses may help control and contribute to clearance of mf of O. volvulus.

Article Synopsis
  • National public health institutes (NPHIs) in Africa played a vital role in COVID-19 responses, utilizing innovative strategies and technology for effective management and communication.
  • These institutions improved laboratory capacities and forged stronger public-private partnerships, establishing systems expected to sustain beyond the pandemic.
  • Challenges remain, including the need for more trained staff, better data sharing, and addressing inequalities in health service access, emphasizing the importance of ongoing investment in NPHIs to enhance public health infrastructure.

Background: The World Health Organization has targeted lymphatic filariasis (LF) for elimination as a public health problem and recommends, among other measures, post-elimination surveillance of LF. The identification of sensitive and specific surveillance tools is therefore a research priority. The Wuchereria bancrofti-specific antigen Wb123-based enzyme-linked immunosorbent assay (Wb123 ELISA) detects antibodies to the recombinant Wb123 antigen of W.

Article Synopsis
  • COVID-19 began in December 2019 in China and was declared a pandemic by March 2020, with Togo reporting its first case on March 5, 2020.
  • A survey conducted from April 23 to May 8, 2020, aimed to estimate the prevalence of SARS-CoV-2 among high-risk groups in Lomé, using oropharyngeal swabs and blood samples for testing.
  • Results showed a low overall prevalence of 1.6% among 955 participants, with government measures likely contributing to the low rates of infection, leading to a recommendation for targeted screening in these high-risk populations.

Background: In Togo, the prevalence of Hepatitis B Virus Surface Antigen (HBsAg) among young people aged 15-24 years was estimated at 16.4% in 2010; however, risk factors for HBsAg carriage are poorly documented. We sought to identify risk factors for HBsAg carriage and the serological profile of HBsAg carriers in Lomé (capital city of Togo).

Background: The only available vaccine that could be potentially beneficial against mycobacterial diseases contains live attenuated bovine tuberculosis bacillus (Mycobacterium bovis) also called Bacillus Calmette-Guérin (BCG). Even though the BCG vaccine is still widely used, results on its effectiveness in preventing mycobacterial diseases are partially contradictory, especially regarding Buruli Ulcer Disease (BUD). The aim of this case-control study is to evaluate the possible protective effect of BCG vaccination on BUD.

Background: In a previous study PCR analysis of clinical samples from suspected cases of Buruli ulcer disease (BUD) from Togo and external quality assurance (EQA) for local microscopy were conducted at an external reference laboratory in Germany. The relatively poor performance of local microscopy as well as effort and time associated with shipment of PCR samples necessitated the implementation of stringent EQA measures and availability of local laboratory capacity. This study describes the approach to implementation of a national BUD reference laboratory in Togo.
