Chelsea assumed a ninth-minute lead at Villa Park as Enzo Fernandez turned in Pedro Neto's cross, but Villa came roaring back in the second half.
Substitute Marcus Rashford supplied two assists for fellow loanee Marco Asensio, with Jorgensen letting the Spaniard's second strike go straight through him.
Chelsea have lost two Premier League games this season having led at half-time, having only suffered one such loss in the last five seasons combined.
Jorgensen was promoted to the role of first-choice goalkeeper earlier this month, with Robert Sanchez being dropped after committing five errors leading to goals this season – the most of any player in the Premier League.
Asked if he was worried about the situation, Maresca told BBC Sport's Match of the Day: "I am always concerned, even when we were winning games, I was concerned.바카라 웹사이트
"Now I am, for sure. The problem with that with goalkeepers is it is a delicate position and when they make a mistake, everyone can see.바카라 웹사이트
"Unfortunately today, our goalkeeper made a mistake. This is a moment we need to support each other and try to stay strong."
Chelsea had 15 shots to Villa's 12 throughout the game, with the majority of their chances coming in the first half – when the Blues created 1.53 expected goals (xG) to Villa's 0.82.
"If you are not clinical, this league is always open – if you make a mistake, like we did on the second goal unfortunately," Maresca said.바카라 웹사이트
"When we have the chance, we have to take it. Once again today, we showed we can be good for long parts of the game. But that's not enough.바카라 웹사이트
"The performance has to be complete. We need to score goals when we have the chance and defend well, but I thought we defended well today. It is a moment where we were also a bit unlucky."
Villa boss Unai Emery, meanwhile, was delighted with the impact made by January arrivals Asensio and Rashford.바카라 웹사이트
He said: "We had the necessity to improve the squad and to have more players to help with our objectives: trying to be in the top seven or eight and trying to compete in the FA Cup and the Champions League.
"Of course, we brought the players in thinking about improving it. Then we had to try and adapt quickly, with a lot of meetings and getting information on the field."
