In the Region of the Americas, between epidemiological week (EW) 1 and EW 52 of 2018, a total of 560,586 cases of dengue were reported (incidence rate of 57.3 cases per 100,000 population), including 336 deaths. Of the total cases, 209,192 (37.3%) were laboratoryconfirmed and 3,535 (0.63%) were clas...sified as severe dengue. Cases reported in 2018 were higher than the total reported in 2017 but lower than the historical average reported in the previous 11 years (2006-2016) (Figure 1). Similarly, the proportion of cases of severe dengue and dengue with warning signs reported in 2018 was higher than the previous two years, but lower than the preceding ten years, and it remains below 1% which was reached in 2015.

WHO guidelines on the pharmacological treatment of persisting pain in children with medical illnesses
Après plus de trois ans sans cas, Haïti a signalé le 2 octobre 2022 un ensemble de cas de choléra dans la zone métropolitaine de Port-au-Prince, alors que le pays était sur le point d'être déclaré exempt de choléra.
Cette résurgence du choléra en Haïti survient dans un contexte opérat...ionnel complexe, au milieu d'un environnement socio-politique instable marqué par des blocus, des pénuries de carburant, des activités de bandes criminelles et une insécurité galopante. Les troubles civils et le manque d'accès aux communautés touchées aggravent la crise humanitaire complexe et entravent les efforts de réponse d'urgence.

At the time of writing, the novel coronavirus pandemic had reached every region of the world, with millions of infections globally and untold disruptions to nearly every aspect of daily life.
After more than three years without cases, Haiti reported on 2 October 2022 a cluster of cholera cases in the metropolitan area of Port-au-Prince, just as the country was on the verge of being declared cholera- free.
This cholera resurgence in Haiti is happening in a complex operational context, am...id a volatile socio- political environment marked by blockades, fuel shortages, criminal gang activity and rampant insecurity. Civil unrest and lack of access to the affected communities are deepening the complex humanitarian crisis and hindering emergency response efforts.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).
