Scotland were easily beaten 7-2 by Switzerland in Halstad before hitting back with a 9-7 victory over France in their second match of the day.
The win was a case of too little too late for the Scots, however, and they stay seventh in the 10-team A group with a record of three wins and four losses.
Scotland's remaining two matches are against hosts and table-toppers Sweden and last-placed Hungary.
In the early match, the team once again started with David Murdoch playing at fourth and skip Tom Brewster at third because of illness.
But it got even worse as Murdoch had to leave the ice at the end of the fifth end after feeling unwell, with Scotland trailing 3-1.
Brewster and co eventually fell to a 7-2 defeat in the ninth end - and Brewster said their trip was going from bad to worse.
"It doesn’t half feel like the curling gods are against us," said Bewster.
"We’ve got one guy being sick and another looking like he's coming down with flu, so it’s a war of attrition. It's horrible. We felt great last night and we felt good this morning.
"We just didn’t take out chances, and we had plenty. David had a tough shot in four but it was there, and that was it.
"The game hinged on that. We stayed on for a few ends because the ice was getting really flat and we just thought we'd see if we could get something."
Sweden continued their imperious form with a sixth straight win in their early match, 8-2 over Russia.
But the hosts lost their perfect record later in the day following a 9-5 defeat to Denmark. Norway took advantage to draw level at the top of the group, both nations now boasting 6-1 records.
The Czech Republic and Denmark are tied for third with 5-2 records, while Russia and Switzerland follow after winning four and losing three of their matches.
Hungary prop up the table as the only team yet to post a victory, with France and Germany just ahead with one win each to their names.
In women's action, there was better luck for Eve Muirhead's team as they put a late defeat to Sweden on Monday night behind them to down both Germany and Denmark.
Defending champion Muirhead lost 9-2 to Sweden but came bouncing back with a 7-3 victory over Germany on Tuesday.
That was followed by a 9-2 success against Denmark, leaving Scotland's women in contention to defend their title.
With two matches remaining - against Russia and Hungary - Scotland sit third in the table with a 5-2 record - the same as Denmark and Switzerland. Russia are on top, along with Sweden, having lost just once each.
England's women won one and lost one in Group B to leave then in sixth place with a 3-5 record at the end of the day.
