Centers for Disease Control and Prevention (CDC) categorizes germs into three main categories

The Centers for Disease Control and Prevention (CDC) categorizes germs into three main categories—urgent, serious, and concerning—based on their potential to cause public health threats and the urgency of action required to address them. Additionally, the CDC maintains a watch list of pathogens that are closely monitored due to emerging resistance or other factors. Here's an overview of each category along with examples: Urgent Threats : Urgent threats are pathogens that pose an immediate public health risk due to their high levels of antibiotic resistance, limited treatment options, and potential for widespread transmission. Examples include: Carbapenem-resistant Acinetobacter Drug-resistant Candida Auris Clostridioides difficile Carbapenem-resistant Enterobacteriaceae (CRE) Drug-Resistant Neisseria Gonorrhoeae Serious Threats : Serious threats are pathogens that are moder...
