Answer

"Liverpool have won 5 games in a row". (They won all of them - no gaps)

"There has been a spate of attacks on hedgehogs" (often used for bad things)

"There has been a flurry of activity on the stock market". (The most 'original' expression I can think of is a flurry of snow - your explanation 'sudden burst' is correct)

And as you say -  a streak is often used with continued luck, bad luck, good fortune, misfortune... also a "stroke of luck" is one piece of good luck!

Answer

What you wrote is already pretty definitive.
