RESUMO
In 2020, Montana, USA, reported a large increase in Colorado tick fever (CTF) cases. To investigate potential causes of the increase, we conducted a case-control study of Montana residents who tested positive or negative for CTF during 2020, assessed healthcare providers' CTF awareness and testing practices, and reviewed CTF testing methods. Case-patients reported more time recreating outdoors on weekends, and all reported finding a tick on themselves before illness. No consistent changes were identified in provider practices. Previously, only CTF serologic testing was used in Montana. In 2020, because of SARS-CoV-2 testing needs, the state laboratory sent specimens for CTF testing to the Centers for Disease Control and Prevention, where more sensitive molecular methods are used. This change in testing probably increased the number of CTF cases detected. Molecular testing is optimal for CTF diagnosis during acute illness. Tick bite prevention measures should continue to be advised for persons doing outdoor activities.

Children represent one quarter of the US population. Because of its enormous size and special needs, it is critically important to address this population group in pandemic influenza planning. Here we describe the ways in which children are vulnerable in a pandemic, provide an overview of existing plans, summarize the resources available, and, given our experience with influenza A(H1N1), outline the evolving lessons we have learned with respect to planning for a severe influenza pandemic. We focus on a number of issues affecting children-vaccinations, medication availability, hospital capacity, and mental health concerns-and emphasize strategies that will protect children from exposure to the influenza virus, including infection control practices and activities in schools and child care programs.
