A total of seven medals won by Russia's Polina Frolova at this year's World Ski Orienteering Championships (WSOC) in Krasnoyarsk and the European Ski Orienteering Championships (ESOC) in Imatra have now been officially re-allocated following her positive drugs test.

They include the women's relay at the WSOC in March, where Frolova skied the second leg, as Russia beat Finland by 2min 22sec to win the gold medal.

The Finns have now been promoted to the gold medal, Czech Republic to silver and and Estonia to bronze.

That gold was one of five medals won by Frolova in the Russian resort.

But she has been stripped of them all following a positive test for the heart disease drug meldonium detected in a urine sample she gave on February 8 at the ESOC in Finland following the mixed sprint relay.

Frolova had combined with Andrey Lamov to beat Sweden 3 in a photo finish. 

The Swedish pair of Frida Sandberg and Ulrik Nordberg will now inherit the gold medal.

Russia 2 team Mariya Kechkina and Sergey Gorlanov will be promoted to the silver. 

Under the rules of the International Orienteering Federation (IOF), several teams can participate from each nation, but only the best team counts in the official results.

The 31-year-old Frolova will also lose the gold medal she won in the women's relay, where she skied the second leg.

The gold medal will go to Finland, the silver to Sweden and bronze to Czech Republic. 

Frolova has also lost her silver medals from the WSOC in the mixed sprint relay, women's sprint and women's middle-distance and bronze in the women's long-distance 

Three other results of Frolova at the ESOC were disqualified, comprising her fourth-place finish in the sprint event, fifth-place finish in the long-distance event and sixth-place finish in the middle-distance event.

"At their meeting in Tartu, Estonia, in connection with the World Orienteering Championships, the IOF Council have come to the decision that the medals will now be redistributed according to the new results," the IOF said in a statement. 

As well as being disqualified from all her competitions in 2017, Frolova was last month given a four-year suspension by the IOF. 

Meldonium hit the headlines in March last year when another Russian, five-time Grand Slam champion Maria Sharapova, announced she had tested positive for the substance at the Australian Open two months earlier.

Meldonium was only added to the WADA banned list on January 1 in 2016.

It was moved from the monitored to the prohibited list by WADA due to "evidence of its use by athletes with the intention of enhancing performance".
