Overview of case definitions and contact tracing indications in the 2022 monkeypox outbreak

Giovanni Guarducci et al. Infez Med. .

Abstract

Background: In 2022, a new outbreak of the Mpox virus occurred outside of Africa, its usual endemic area. The virus was detected in European, American, Asian, and Oceanian countries where Mpox is uncommon or had not been reported previously and where the spread was rapid. The study aims to compare the case definition and the indications for contact tracing in case of Mpox infection among the World Health Organization (WHO), the European Centre for Disease Prevention and Control (ECDC), and four European Countries.

Methods: From August 2022 to November 2022, we conducted research, first on the WHO and ECDC official websites and then on the official websites of the Ministry of Health or National Health Agencies of four European Countries (Italy, France, Spain, and Portugal). All reports found were compared to enlighten the differences in the definition of the case and indications for contact tracing.

Results: The WHO divides the case definition into four categories: suspected, probable, confirmed, and discarded, while the ECDC divides cases into confirmed and probable. The ECDC defines contact as close and others, while the WHO divides it into high, medium, and minimal risk. The four countries analyzed show heterogeneity in both the case definitions and the indications for contact tracing.

Conclusions: Our analysis revealed heterogeneity in the case definition between the WHO and ECDC. Different countries followed different indications or have given their indications for both the case definition and contact tracing indications. Harmonization strengthens public health preparedness and response and creates unified communication.

Keywords: Mpox outbreak; epidemiological and virological surveillance; monkeypox; public health authorities.
