Austria's daily Covid infections hit a new record on Thursday as the hardest-hit provinces started planning a full lockdown.
Pressure is growing on the government to do the same nationally, instead of the country's current lockdown for the unvaccinated.
Roughly 66 per cent of Austria's population is fully vaccinated, one of the lowest rates in western Europe. Its infections are among the highest on the continent, with a seven-day incidence of 971 per 100,000 people.
With colder weather setting in as winter approaches, cases have surged across Europe, prompting governments to consider reimposing unpopular lockdowns.
While the Netherlands has imposed a partial lockdown that applies to all, Austria has sought not to impose extra restrictions on the vaccinated.
Daily infections on Thursday rose above 15,000 for the first time, reaching 15,145. The peak of the biggest wave of infections before this was 9,586 about a year ago, when the country went into full lockdown.
Hardest hit
The hardest-hit of Austria's nine provinces are Upper Austria, a stronghold of the far-right and vaccine-criticising Freedom Party, which has the country's highest infection rate and its lowest vaccination rate, and neighbouring Salzburg.
The conservative governor of Upper Austria, Thomas Stelzer, said on Thursday that if Austria did not lock down nationally, his province would, Austrian media reported.
"If no national lockdown is ordered tomorrow, there will definitely be a lockdown of several weeks in Upper Austria together with Salzburg. We will coordinate with our neighbouring province (Salzburg) and with the federal government," newspaper Kurier quoted Mr Stelzer as telling Upper Austria's parliament.
The conservative governor of Salzburg, Wilfried Haslauer, told news agency APA his province is indeed preparing a lockdown. Austria's nine governors are holding a meeting on Friday and have invited conservative chancellor Alexander Schallenberg and health minister Wolfgang Mueckstein.
