All the debilitating inward signs of a cold - aches, pains, tiredness and brain fog - without the obvious symptoms of congestion and coughing. Still enough to lay you out for a couple of days, even though your immune system is doing its best to hide your weakness from predators.
I was off work for a chunk of last week with a stealth cold. Knocked me flat for a day or two but didn't really go anywhere. Annoying.
