According to Johns Hopkins University, there are more than two-point-nine million confirmed cases of Covid-19 in the US.
And medical experts warn the country is still heading in the wrong direction.
New cases are surging in at least 32 states and some fear a lack of social distancing during the Fourth of July weekend may cause those numbers to keep climbing.
Health experts say that cases in the US and Southwest are rising so fast that contract tracing is no longer possible.
And a new study published in the proceedings of the National Academy of Sciences finds asymptomatic or pre-symptomatic people may be responsible for half of the country’s Covid-19 cases.
The study found that more than one-third of these infections would need to be identified and isolated to suppress a future outbreak.
Researchers say even immediate isolation of all symptomatic cases would not be enough to get the spread under control.
The model assumed that Covid-19 may be the most contagious during the pre-symptomatic stage, which is uncommon for a respiratory infection.
Meanwhile Atlanta Mayor Keisha Lance Bottoms and her husband are among the latest to test positive for the virus.
Bottoms said Monday she has no symptoms.
Bottoms is one of the top prospects to be Democratic presidential nominee Joe Biden’s running mate.
