今職場でインフルエンザ(風邪)が流行ってますって英語でなんて言うの？

It is correct to say that the flu is going around a certain area. But there are also other ways to express the thought of an illness spreading. For instance, using the verbal phrase "stricken by" or "sticken with" effectively emphasizes the seriousness and contagiousness of the illness under discussion. This verb is commonly used when referring to people catching a disease. I was stricken with malaria during my travels in Africa. Alternatively, one could simply say that his/her coworkers are sick with the flu. The simplicity of this sentence helps the audience to understand the issue and infer that an illness is going around or spreading.

There is often flu 'spikes' that can be due to a couple of conditions. Some of these have to do with the season and also different changes in population - major events etc in a particular country, an influx of tourists from different parts of the world. Saying that you "caught the flu at work." suggests that you caught the flu of someone at work. We say "I 'caught' the flu" or "I hope I don't "catch" the flu." as if it were a ball that can be caught. This is because the flu is a virus that is highly contagious and can spread quickly through condensed areas - hence increased numbers of flu being diagnosed during certain periods of time. Saying that "The flu is going around." indicates that many people have the flu and that you are at greater risk of catching it!

Idioms can be very useful to bring extra color and add "zing" to any conversation! Contageous diseases...(like the flu) are said to "spread like wildfire" meaning very fast indeed... "Everyone at work is " down with the flu"...its spread like wildfire"

Of course, people say "the flu" is going around the office or the factory, but sometimes people call it "a bug", which also means "an insect". If you are lucky, you are only sick for one day, and you can call it a "24-hour bug". I read online that using "bug" to mean "illness" is at least 100 years old. About 10 years ago, characters on the popular TV police drama "The Wire" used "the bug" to refer to HIV/AIDS. I think that usage has grown in popularity since then.

The flu virus is spreading quite rapidly at my workplace right now. This is a good way to explain that many people are infected by the flu virus at your place of work."Spread" means "extend over a large or increasing area." which means many of your colleagues are starting to catch it. The flu virus is going around where I work. This is the simplest way to express the idea because "going around" has the same meaning as spreading.

The above would be a good way of explaining the flu is going round work and everyone is catching it.

"The flu is going around at work" 'Going around' is the term used when talking about things such as illness,gossip etc, around a workplace/school etc. ex. "Chicken Pox is going around at school" "The flu has spread around work" 'Spread' is also another term used for 'going around', to spread something means its has been separated/moved over a surface/through things/people.
