If resigning from a government post counts as a consequence, then there are a few UK examples:
In April 2020, Scotland's chief medical officer resigned after making two trips to her second home during the coronavirus lockdown.
In May 2020, Professor Neil Ferguson quit as a government adviser on coronavirus after admitting an "error of judgement", when "a woman he was said to be in a relationship with visited his home in lockdown".
Also: in September 2020, Margaret Ferrier, a Member of Parliament, travelled by train with COVID symptoms, and then again after a positive test. She was suspended from her party (the SNP), and later arrested and bailed.
(MPs can't be ordinarily be forced to resign; but they automatically lose their seat if sent to jail for more than one year, and can be subject to a recall petition if jailed for less than one year (source) or after a suspension from the Commons. Depending on the outcome of this case, that could still happen.)
UPDATE: In June 2021, Matt Hancock, the Secretary of State for Health and Social Care, resigned "after he breached social distancing guidance by kissing a colleague".
