The Operational guide: use of referral laboratories for the analysis of foodborne hazards in the Pacific aims to strengthen the food analysis capacity of Pacific Island countries and areas by identifying national and reference laboratories capable of testing for priority foodborne hazards. The Pacif...ic Island countries and areas are often vulnerable to food safety incidents and emergencies due to their geographical distribution and dependence on food imports. The guide outlines key considerations for selecting referral laboratories and submitting samples to them, enabling continuous improvement of food safety systems and providing safe food for all. The target audiences are health and food safety authorities.

L’ulcère de Buruli, une infection causée par Mycobacterium ulcerans, touche plus de 33 pays dans le monde, mais un peu moins de la moitié seulement de ces pays communiquent régulièrement des données sur la maladie à l’OMS. La plupart des cas notifiés se trouvent dans les sous-régions d...Afrique occi-
dentale et centrale. Le mode de transmission de l’ulcère de Buruli n’est pas connu. Environ la moitié des personnes touchées sont des enfants de moins de 15 ans et les deux sexes sont concernés à parts égales.
Le diagnostic repose principalement sur l’observation des caractéristiques cliniques et épidémiologiques.
Parmi les quatre méthodes de confirmation utilisées (examen microscopique, amplification en chaîne par polymérase (PCR), histopathologie et mise en culture), la PCR est la plus rapide et la plus courament employée. D’autres méthodes rapides, comme l’utilisation de la chromatographie sur couche mince par fluorescence pour détecter la mycolactone dans les lésions des cas suspects d’ulcère de Buruli, sont actuellement à l’étude dans quatre pays d’Afrique. Des travaux de recherche sont en cours pour mettre au
point des tests utilisables sur le lieu des soins. Le traitement de l’ulcère de Buruli consiste à administrer une association d’antibiotiques (rifampicine et clarithromycine) pendant 8 semaines. Des traitements complémentaires, comme le soin des plaies, les greffes cutanées et la prévention des incapacités, sont nécessaires dans certains cas pour parvenir à une guérison complète.
La cible fixée par l’Organisation mondiale de la Santé (OMS) exigée des pays pour assurer la lutte contre l’ulcère de Buruli est la confirmation d’au moins 70 % des cas par PCR pour chaque pays. Tous les pays d’endémie disposent d’au moins un établissement doté des moyens nécessaires pour effectuer les tests de PCR pour la confirmation des cas. Cependant, la plupart des pays de la Région africaine n’ont pas réussi à atteindre la cible fixée. Un déclin du taux de confirmation a même été observé.

By end of March 2022:
42 COVID-19 detection laboratories were assessed in the 1st Quarter 2022.
23 (55%) Labs are reported fully functional, while 19 (45%) requires assistance to fully operate (i.e., medical supplies, equipment, maintenance, and staffing).
34 (89%) labs have RT-...PCR machines, while 4 (11%) doesn’t have.
Most laboratories operate 1 shift of 8 hours 13 (34%), followed by 2 shifts of 16 hours 11 (29%).
Over 1000 testing capacity per day is reported in Tripoli Biotechnical Centre Lab (5,000), Azzawya NCDC Lab (2,500), Tripoli NCDC public health lab (1500), Misrata NCDC Lab (1,300), and Misrata Medical centre Lab (1,300).
The reported needs ranked per priority are equipment, consumables, and staff training; consequently.

Technical guidelines for testing for COVID-19 in the clinical laboratories of the National Integrated Health System.
Buruli ulcer is caused by infection with Mycobacterium ulcerans. The disease is reported in more than 33 countries worldwide, but only about half of these countries regularly report data to WHO; most cases are reported from subregions of West and Central Africa. The mode of transmission is not known....
About half of those affected are children aged under 15 years; there is no gender difference. Diagnosis is based mainly on clinical and epidemiological characteristics. Of the four methods used for laboratory confirmation (microscopy, polymerase chain reaction (PCR), histopathology and culture), PCR is the most rapid and widely used. Other rapid methods for detection of mycolactone in lesions from suspected cases, such as fluorescent thin-layer chromatography, are under evaluation in four countries in Africa.
Research to develop point-of-care tests is in progress. Treatment of Buruli ulcer comprises 8 weeks of combined antibiotics (rifampicin and clarithromycin). Complementary therapies such as wound care, skin graft and prevention of disability are needed in some cases to ensure full recovery.
The target set by the World Health Organization (WHO) for control of Buruli ulcer is for countries to achieve a rate of case confirmation by PCR of at least 70%. All endemic countries have at least one PCR facility to support confirmation of cases. However, most countries in the WHO African Region have not been able to reach the target, and the rate of case confirmation has been declining

Timely detection of novel coronavirus (2019-nCoV) infection cases is crucial to interrupt the spread of this virus. We assessed the required expertise and capacity for molecular detection of 2019-nCoV in specialised laboratories in 30 European Union/European Economic Area (EU/EEA) countries. Thirty-...eight laboratories in 24 EU/EEA countries had diagnostic tests available by 29 January 2020. A coverage of all EU/EEA countries was expected by mid-February. Availability of primers/probes, positive controls and personnel were main implementation barriers.

Countries who have no testing capacity can send their samples to the WHO appointed 2019-nCoV referral laboratories for testing. National 2019-nCoV laboratories with limited experience are encouraged to send the first five positives and the first ten negative 2019-nCoV samples to their referral labor...atories for confirmation.

This document provides countries with recommendations for structuring a public health entomology laboratory network. The document will help countries to identify their areas of need and determine how the entomology network can be strengthened, especially in the context of a decentralized health syst...em. The recommendations also consider the different degrees of development and different entomological research needed to support disease prevention and control activities.
