Abstract:
In November 2024, a case of clade Ib mpox was confirmed in Canada. Here, we describe the events that led to laboratory confirmation of clade Ib monkeypox virus (MPXV) and the public health response. Genomic analysis of the Canadian clade Ib MPXV revealed a number of APOBEC3-related mutations suggesting sustained human-to-human transmission. These findings expand the number of countries with travel-related clade Ib mpox and highlights the continued need for mpox monitoring of potential human adaptations or new transmission patterns.

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
