Suarez and his team-mates were quickly back on the front foot following the restart, though, and Cavani fed his strike partner for a low drive that El-Shenawy blocked bravely.
Salah was only fit enough to be named on the bench as Hector Cuper's side took on their South American opponents on Friday afternoon.
Salah - who scored 44 goals in all competitions for the Reds last season - joined the rest of the Egypt squad during a training session at the Ahmed Arena in Grozny on Saturday evening.
It was one of those games in which both sets of defences came out on top.
The win gave the group favourites a serious boost after Russia's shock 5-0 win against Saudi Arabia in the opening match.
A goal from Jose Maria Gimenez shocked the Pharaohs of Egypt who did well to keep Cavani and Suarez from having much space.
The two nations have played each other just once before, in an worldwide friendly that the South Americans won 2-0, but Friday's match is nearly impossible to predict.
According to oddsmakers, Uruguay is a -179 favorite to win on the moneyline.
Uruguay ran away as winners in their opener but would expect a better show from their attackers next when they go up against Saudi Arabia in their second game on Wednesday.

Will Salah help Egypt escape Group A? With a victory, Uruguay could reach the next stage with a game in hand against host Russian Federation on June 25.
He thumped the turf on 73 minutes when Elshenawy smothered at his feet, and seven minutes from the end the stopper was at it again, palming Cavani's drive over. And Cuper hinted on Thursday that it was the player who had the final say whether to play.
