Condensation occurs where air meets a surface that is below the dewpoint temperature. This is mainly in winter or in warmer weather on cooling coils when mechanical cooling is needed.
Humidification is mainly used in hospitals and when the outdoor air contains very little moisture. (Winter or Desert). Hospitals have high ventilation rates, sick people and immune compromised people. Without humidification, the humidity in the occupied space can drop far below the optimum for health and comfort of around 50%

Anywhere that you cannot afford to shut down the cooling you will have more than one cooling tower so you can continue operation if a tower is out of service. (eg Hospital, Critical computer centre, Critical Process)

As numbers get close to 100% we have a tendency to think of them as much the same and sometimes miss something important.
Let's look at the numbers based on who hasn't tested positive for EBV.
5% in the general population 0.1% in the population with MS
This is a ratio of 50:1 which doesn't seem likely to be meaningless to me.
