Biden camp says he again tests negative for COVID-19 ahead of campaign travel
Campaign says will continue to observe public health guidelines
Joe Biden's campaign says the Democratic presidential nominee tested negative for coronavirus Sunday.
The results come five days after Biden spent more than 90 minutes on the debate stage with U.S. President Donald Trump.
The president was diagnosed with COVID-19 days after the debate, and he remains hospitalized.
Biden had two negative tests on Friday, as well.
He is scheduled to travel Monday to Florida.
His campaign said it will continue to observe public health guidelines on masks, social distancing and crowd sizes.
