It's illegal to select an individual for redundancy for something like this.
The flu-like symptoms are accompanied by a fever. Contrary to the press hype, it's really no more severe than any other flu strain. Thousands die from the usual seasonal flu strains each year but that doesn't make the headlines, whereas the mortality rate figures for this strain are being constantly revised *downward*.
Assuming you do have it and your bad feeling isn't just psychosomatic, the incubation period is 5-7 days and will present as the usual flu like symptoms combined with a fever and posssible nausea. Current advice is to call the NHS helpline if you think you are presenting these symptoms, rather than go to the local surgery and spread it around.
