Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'вспышка' for a flash of light or brief emotion. 'Outbreak' implies sustained spread. For a single, short event like a 'вспышка гнева', use 'outburst'.
- Not a direct equivalent of 'эпидемия' (epidemic). 'Outbreak' can be smaller in scale.
Common Mistakes
- Using it for positive things (e.g., 'an outbreak of generosity').
- Confusing it with 'outburst' (short, emotional).
- Using as a verb ('The disease outbroke' is incorrect; use 'broke out').

FAQ
Frequently Asked Questions
No, 'outbreak' is solely a noun. The corresponding verb is the phrasal verb 'break out' (e.g., 'War broke out').
Almost never. Its core meaning involves negative, uncontrolled events like disease, violence, or fire. Using it for positive things sounds strange and is considered incorrect.
'Outbreak' is the broadest term for a sudden occurrence. An 'epidemic' is a large-scale outbreak affecting a community or region. A 'pandemic' is an epidemic that has spread over multiple countries or continents.
The most common pattern is: '[Article] + outbreak + of + [negative phenomenon]'. For example: 'An outbreak of looting followed the earthquake.' or 'The outbreak was contained within days.'
