My Girlfriend Cleaned Out Her Office At Work Using Bleach

My girlfriend cleaned out her office at work using bleach however it is an unvented area and she stayed in there for a good few hours with a lot of the stuff. I walked past at one point gagging from the smell. About four hours later she's now constantly vomiting with a huge fever, she says her eyes are sore and her insides hurt and she's struggling to breathe. Do you think this is due to the bleach or does she just have a bug and it's all a coincidence?
