(CNN) — Total cases of Covid-19 reached around the 33.9 million mark in the United States by mid-July 2021. Domestic US travel picked up considerably in the summer of 2021. Very few states had travel restrictions at the peak of summer -- and the few rules that are remaining are generally less strict. Despite all the eliminated restrictions, troubling signs have emerged. The combination of unvaccinated people and the more contagious Delta strain of coronavirus has led to new Covid-19 surges in 45 states. As of July 13, the Centers for Disease Control and Prevention still warned against nonessential travel for people who are not fully vaccinated. Fully vaccinated travelers do not need to self-quarantine, and they don't need to test negative before or after their travels unless the destination requires it. If you do decide to travel to another state or territory, you should still check out the latest local guidance before you go. Even though almost all states have dropped their travel restrictions, their official websites have important Covid-19 safety information. This list is alphabetical and includes links to state websites:
