Potential Causes of Increased STD Rates

Before looking at the numbers, it’s important to remember there are several factors at play that influence how common STDs are in any given area of the US. Even throughout the pandemic, STD rates continue to increase, but there appear to be simple explanations as to why. For those who continued seeing a physician, virtual visits meant that more diagnoses were missed. Labs and testing supplies were in short supply as the focus shifted to COVID-19. While these issues may no longer be as prevalent, one of the biggest issues that still contributes to increasing STD rates is lack of education and access to necessary sexual health clinics and resources.
