The death toll from the coronavirus outbreak surged past 1 000 on Tuesday.
Most cases overseas have involved people who had been in Wuhan, the quarantined central Chinese city where the virus emerged late last year, or people infected by others who had been at the epicentre.
United said Saturday in a statement that Ighalo had been left out of the Spain squad to avoid any potential problems related to the killer virus on re-entry to Britain.
However, United manager Ole Gunnar Solskjaer told the club’s website Ighalo will be in the squad for a match that could have a crucial bearing on who finishes in the top four this term and qualifies for the Champions League next season.
“Yeah, he is going to travel with us,” said Solskjaer.
“We will just see his fitness work this week and I think we will get him sharp.
“We want to integrate him as quickly as we can because, of course, he is desperate to play for us.”
Ighalo, who has played his club football in China for the past three years after joining Changchun Yatai from Watford, was signed as emergency cover for the injured Marcus Rashford.
Chelsea presently occupy the fourth and final Champions League spot and are six points clear of eighth-placed United.
The other three Champions League places look destined for Liverpool, Manchester City and third-placed Leicester, who have a 10 point advantage over fifth-placed Sheffield United and a game in hand to boot.
