Can bacteria live on a dry surface?

Although viruses can survive outside a host on household surfaces, their ability to duplicate themselves is compromised-shortening the virus’s life span. Humidity also makes a difference; no bacteria or virus can live on dry surfaces with a humidity of less than 10 percent.

How long do cold germs stay on surfaces?

Cold viruses can survive on indoor surfaces for up to seven days, but are infectious only for about 24 hours. Generally, they last longer on hard, nonporous surfaces such as plastic or stainless steel. The virus is less likely to live as long on soft, porous surfaces such as tissues.

Instead, they must invade a host organism and hijack its genetic instructions.
