The short answer is yes.

Keep in mind that not all viruses are created equal; there are both RNA and DNA viruses and enveloped and non-enveloped viruses. These factors are more important with chemical disinfectants/sterilents and the such. Many viruses are inactivated by simply becoming exposed to less then ideal (for the virus) environmental conditions such dehydration or exposure to UV.

Some bacteria (spore forming- i.e. some Bacillus spp.) are more resistant to adverse environmental factors and may require either greater lengths of time, higher pressures (use of pressure cooker or autoclave) or higher temperatures (dry heat) to achieve organism destruction.
