It's possible. Sort of.
Assuming this virus has a fatality rate of around 0.3%, then they'd need around 70-80% of their 10,000,000 ish population to catch it to achieve it, which would mean a total death rate of 21,000 to 24,000 people. It also means the disease will spread quicker throughout their population simply because there's fewer to infect yet the rate in which the virus spreads exponentially stays the same. So they'd get a relative small big "hit" to their health system.
It's sort of doable with that low of a population to be honest. The difference here is we have more than six times the population, so for us it'd be a death rate of around 160,000, done via a massive spike in deaths over a longer period of time.
It's why it's difficult to compare country to country, because Sweden will look "good" compared to us on the surface no matter what happened. We in the UK simply couldn't have done what Sweden have done.
