Ings has been in isolation since that match and is due to come out of it on Friday ahead of their game with Leicester City.
Ings, 28, played 77 minutes and scored Southampton’s winner in the match at St Mary’s on January 4. He had tested negative before the game.

Saints manager Ralph Hasenhuttl admitted Ings may have been contagious during the game
The striker celebrated with his team-mates after netting the winner but Hasenhuttl confirmed there had been no other positive tests in his squad since.
Ings is set to return to training on Friday but may not be involved against Leicester City on Saturday evening.
Southampton haven’t played since the Liverpool game following the postponement of their FA Cup third round tie with Shrewsbury Town because of a Covid outbreak at the League One club.
Hasenhuttl was speaking about the latest guidelines urging footballers to cut out close contact in their goal celebrations when he revealed Ings’s status.
He said: ‘After the last game against Liverpool, we had one positive test. Danny Ings has been out now for 10 days in self-isolation.
‘That [Ings result] meant that in this game maybe also he was contagious I think its 48 hours before a positive test you can be and we had no further positive tests so far and that means our protocols we are sticking to and our guidelines we really follow them and are very disciplined are definitely good and when you stick to these guidelines then you can also work like we do it every day together, celebrate together.

‘We did it after the Liverpool game we did it in the game and I think this is the answer enough. You never know but this showed me when you stick to the protocols that you have [you can] control the risk.
‘And it’s the reason why the Premier League decided to let us play football and this is what we are doing.
‘For me, part of football is the duels, part of football is defending a set-piece where you’re standing together and part of football is celebrating when you score a goal and I think the protocols and experience we made so far shows that it works.’
Goalkeeper Alex McCarthy missed the Liverpool game after a positive test.
Liverpool have not announced any positive Covid results since their game at Southampton. Sportsmail has contacted Liverpool for comment.
Ings’ positive test comes as football is under enormous scrutiny for how it is responding to the coronavirus pandemic and Whitehall sources have told Sportsmail there is ‘growing frustration’ over Covid rule breaches among players.

As Sportsmail revealed on Thursday, a series of urgent meeting have been set up between the Premier League, captains and managers to address new Covid protocols amid fears of government intervention.
A series of stringent measures were sent to clubs in the wake of the new strain of the virus spreading rapidly across the country.
Players were told that they should avoid hugging, high-fives and handshakes when celebrating goals or victories. However, a number of teams celebrated in groups after scoring goals in the midweek Premier League matches.
Sportsmail revealed that the ongoing situation has prompted worried Premier League officials to take action.
They will hold a series of calls with captains, managers and key staff – thought to be safety officers – on Thursday and Friday at 2pm and 4pm.
Four summits will be held on each afternoon. On the calls they are expected to be reminded of the new protocols, the reasoning behind them and the potential impact that repeated non-compliance could have.

Despite being urged not to, players are still celebrating with hugs, high-fives and handshakes
As an elite sport, football is allowed to continue when most of the activities in the country are curtailed during the national lockdown aimed at reducing sky-high rates of coronavirus infection.
Ministers have considered shutting the game down and insist it is hard to justify the additional freedoms it enjoys when the public see footballers flouting the rules they have to follow, including group hugs, dressing room celebrations, as well as going to parties.
Seven Premier League players from five clubs breached social distancing guidelines by attending or organising parties during the festive period.
This was followed by breaches of Covid rules on and off the field in the FA Cup third round when players celebrated goals in huddles and enjoyed a singsong and drank champagne together in the dressing room after two matches.
And now, with the return of Premier League fixtures, players have marked the majority of goals with celebratory scrums, which have horrified health experts for the poor example they set and infuriated frustrated politicians. All of this has increased calls for the game to be shut down.
Meanwhile, Aston Villa’s fixture with Everton on Sunday has become the latest Premier League fixture to be called off because of an outbreak within a club.
A significant number of Villa’s squad are still isolating after a Covid-19 outbreak at the club. The game was meant to be played on January 17 and at present there is no new date offered for the match to take place.
