TNew data from the World Health Organization reveal that the COVID-19 pandemic has disrupted malaria services, leading to a marked increase in cases and deaths.
According to WHO’s latest World malaria report, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide i...n 2020. This represents about 14 million more cases in 2020 compared to 2019, and 69 000 more deaths. Approximately two-thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic.
As in past years, the report provides an up-to-date assessment of the burden of malaria at global, regional and country levels. It tracks investments in malaria programmes and research as well as progress across all intervention areas. This latest report draws on data from 87 countries and territories with ongoing malaria transmission.

Since the emergence of COVID 19 in December 2019, various public health responses measures have been implemented to control the pandemic. Among measures taken by the Africa CDC was the launch of PACT initiative to accelerate COVID 19 testing. Key to the initiative is the engagement of Community Heal...th Workers (CHWs) in risk communication and community engagement (RCCE), surveillance activities for early case identification, contacts tracing and in facilitating referrals for testing and continuum of care.
As of 31 May 2021, Through PACT support, over 17154 CHWs have been trained and locally deployed in 24 AU Member states. The PACT supported CHWs visited more than 2,568,654 households for community engagement activities, active case search and contact tracing, identified 1,618,601 Contacts, 710,167 COVID 19 suspect cases based on the standard case definition and facilitated referrals for 553053 (78%) suspect cases for testing. These efforts were crucial for early identification and isolation of cases in limiting further transmission.

Lorsqu’un virus circule largement dans une population et entraîne de nombreuses infections, la probabilité de mutation augmente. Plus un virus a de possibilités de se propager, plus il se réplique – et plus il est susceptible de muter. L’arrêt de la propagation du virus à la source res...te essentiel. Les mesures actuelles visant à réduire la transmission du virus – dont le lavage fréquent des mains, le port du masque, la distanciation physique et le fait d’éviter de se rendre dans les lieux très fréquentés ou fermés – restent efficaces contre les nouveaux variants car elles réduisent la transmission du virus, qui a donc moins de possibilités de muter. Grâce aux notes explicatives de l’OMS sur les vaccins, en savoir plus sur les vaccins, sur leur fonctionnement et sur la façon dont ils sont fabriqués pour en garantir l’innocuité et y permettre un accès équitable.

Weekly Epidemiological Record No 9, 2022, 97, 61–80
This position paper supersedes the 2016 publication, “Malaria vaccine: WHO position paper-2016.”1 It includes the updated WHO recommendations on the wider use of the RTS,S/AS01 vaccine for the reduction of malaria morbidity and mortality in ...children living in areas of moderate to high malaria transmission. It also incorporates findings from the evaluation of the WHO-coordinated Malaria Vaccine Implementation Programme (MVIP), recommended by SAGE and MPAG in 2015, and from additional studies since 2015.
This paper does not include findings on vaccine efficacy in infants first vaccinated at 6–12 weeks of age. Because of the lower vaccine efficacy observed in this age category, WHO did not recommend pilot implementation or RTS,S/AS01 vaccine introduction for these young infants. Recommendations2 on the use of RTS,S/AS01 vaccine were discussed by SAGE and MPAG during a joint session in October 2021; evidence presented at the meeting can be accessed at https://terrance.who.int/mediacentre/data/ sage/SAGE_eYB_Oct2021.pdf

The spread of Severe Acute Respiratory Syndrome - Coronavirus 2 (SARS-CoV-2) continues to progress, causing damage in several countries of the world due to its rapid transmissibility and significant mortality rates, despite government measures to contain its tra...nsmission, such as movement control, the closing of schools, bans on travel and public gatherings, the mandatory use
of masks, and hand hygiene. The coronavirus disease (COVID-19) has clinical manifestations that are similar to those found in other infections also transmitted through the airways, such as pulmonary tuberculosis (TB) Although TB is a global health problem, it is a curable disease, with affordable treatment and prevention. Nonetheless, it remains one of the leading
causes of death from a single infectious agent worldwide, a situation threatened by COVID-19.

n response to the outbreak, the Africa Centres for Disease Control and Prevention (Africa CDC) has been supporting African Union Member States in responding to the COVID-19 pandemic through a variety of interventions such as non-pharmaceutical interventions, quarantine, testing, isolation, contact t...racing, and clinical management. The Test to Treat guideline aims to increase continental testing efforts and reduce COVID-19 transmission in Africa and put-up response measures to control the impact of the virus, both to limit spread and to reduce substantially the risks of severe health outcomes related to COVID-19 infection. These countermeasures include highly effective vaccines and boosters, rapid testing options for monitoring exposure, and effective therapeutic options for both pre-exposure prevention and treatment of mild-to-moderate disease, oxygen therapy for moderate-severe disease, all of which can potentially be updated efficiently as new variants emerge that may affect the effectiveness of the available tools.

A desperate global thirst for fossil fuels is worsening climate change, leading to more extr...eme weather events that have hit every continent, led to thousands of deaths, and caused $250+ billion in damage in 2021.
• People 65+ and children <1 experienced 3.7 billion more heatwave days in 2021 than the annual average from 1986–2005.
• Heat-related deaths shot up 68% from 2000–2004 to 2017–2021.
• Climate change is abetting infectious disease transmission, warming coastal waters and leading to the spread of Vibrio bacteria like the one that causes cholera, and expanding the reach of the malaria parasite.

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

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.

Lymphatic filariasis (LF) is a preventable neglected tropical disease (NTD) caused by infection with the filarial parasites Wuchereria bancrofti, Brugia malayi or B. timori. Mosquitos in the genera Culex, Anopheles, Mansonia and Aedes transmit the parasites from person to person. Lymphoedema and hyd...rocoele are the visible, chronic clinical consequences of the impairment of lymphatic vessels caused by infection with these parasites. WHO established the Global Programme to Eliminate Lymphatic Filariasis (GPELF) to stop transmission of infection by mass drug administration (MDA) of anthelminthics and to alleviate the suffering of people affected by the disease through morbidity management and disability prevention (MMDP). Since the start of GPELF, the number of infections has been reduced by 74% globally. The latest estimate is that 51.4 million people are infected.

In 1997, the Fiftieth World Health Assembly adopted resolution WHA50.29 on the elimination of
lymphatic filariasis as a public health problem. Preliminary guidance from WHO printed in 2011 referred to “verification” as the official process by which the achievements of the Global Programme to El...iminate Lymphatic Filariasis (GPELF) would be confirmed. For the sake of harmonization, the terminology now used for elimination of lymphatic filariasis as a public health problem is “validation”. In 2015, the WHO Strategic and Technical Advisory Group for Neglected Tropical Diseases endorsed standardized processes for confirming and acknowledging success for all neglected tropical diseases targeted for eradication, elimination of transmission, or elimination as a public health problem.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.
