On 14 August 2024, the Director-General of the World Health Organization (WHO) determined that the resurgence of Mpox in the Democratic Republic of Congo (DRC) and a growing number of countries in Africa constitutes a Public Health Emergency of International Concern (PHEIC). Te...mporary recommendations are being developed with input from the International Health Regulations Emergency Committee and will be available in the coming days.

Since the first confirmed cases in October 2022, Haiti has reported 24,232 suspected cases, including 1,742 confirmed cases and 483 deaths. The most affected areas are in the Ouest Department, particu...larly Port-au-Prince. Children aged 1 to 4 years are the most affected group. The ongoing humanitarian crisis, security issues, and limited access to healthcare have worsened the outbreak, hindering epidemiological surveillance and case reporting. The PAHO/WHO is working with Haitian authorities to respond to the outbreak and mitigate its spread.

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.

In 2018, three countries in the Region of the Americas (Colombia, Haiti, and the Bolivarian Republic of Venezuela) reported confirmed cases of diphtheria. In 2019, Haiti and Venezuela reported confirmed cases.

The first autochthonous case of chikungunya virus (CHIKV) infection in Brazil was in September 2014 in the State of Amapá, and from there it rapidly spread across the country. The present study was conducted in 2016 in the st...ate of Rio Grande do Norte, and the aims were to describe the epidemiological and the clinical aspects of the CHIKV outbreak.
