The US has recorded more than 2.3 million infections and 121,000 deaths to date, the highest number in the world on both counts. States started to ease Covid-19 restrictions in mid-May, but the first wave of the epidemic seems far from over. Infections are on the rise nationwide once again. Here are the latest developments:

• Dr Anthony Fauci, the most senior infectious-disease expert in the US, has told lawmakers the country was seeing a "disturbing surge" in some states. He said there was "increased community spread" in many southern and western states
• California, Florida and Texas were among the states to report a surge in new infections on Tuesday. Seven states have reported record daily increases in hospital admissions, according to analysis by the Washington Post
• California has broken a new daily record for infections for the second day in a row, with more than 6,000 new cases
• Florida’s cases have increased by 3,289, a day after total infections surpassed 100,000
• Texas Governor Greg Abbott has urged people to stay at home, after the state recorded more than 5,000 cases in a single day, breaking its previous record
• Health experts have attributed the rise in cases to the relaxation of social-distancing rules and an increase in testing. In some states, more infections among younger people are being detected
• Dr Robert Redfield, director of the federal Centers for Disease Control and Prevention (CDC), has told Congress Covid-19 has "brought this nation to its knees"
