The Cherries resumed small group training last week with the rest of the Premier League, but were hit by a bomb when goalkeeper Aaron Ramsdale tested positive for the virus.
Speaking to the Daily Mail, Howe admitted the news was a shock and that he and the team were “shaken” by it.
“Of course, the first thing you think about is the health of the player,” said Howe.
“Then his family and loved ones and make sure he hasn’t passed on this infection. There was not a single positive in our group at the start and we were comfortable and we felt good.
“But as soon as you get that positive test, it changes everyone’s mindset. Suddenly everyone feels vulnerable, everyone is alerted to the fact that it is serious and real. “
“Then the unknown comes in. It shook us. We are now waiting for our next tests to see if anyone else is in contact with the player.
“I imagine there is anxiety among the players. I can only imagine that they feel the same as I do. “

The players and managers both participated in separate meetings with Premier League chiefs and the Professional Footballers ’Association and the League Managers’ Association before a vote on Wednesday to begin phase two of contact training.
There is still debate over the resumption of matches, with the Premier League meeting the initial restart date of June 12, and although they are ready to push back to June 19, leaders would prefer June 26.
The big fear on the side of managers is that if the contact training starts this week, it will not leave them enough time for their players to be fit in three weeks.
