Evaluation of Bioaerosoles in Health Center Environments in The City of Valencia, Venezuela
Health center facilities are areas where patients who have a greater or lesser degree of immunological compromise congregate. In this context, the hospital environment is a space where nosocomial diseases could be acquired causing deterioration of the preexistent clinical condition. This study carri...

It seems there is little commitment to applying correct measures to comply fully with standards for patient handling in critical areas, favoring an environment conducive to microbial development, as well as factors such as temperature, relative humidity and air conditioning systems, which do not comply with what is indicated in international technical standards.

Health center facilities are areas where patients who have a greater or lesser degree of immunological compromise congregate. In this context, the hospital environment is a space where nosocomial diseases could be acquired causing deterioration of the preexistent clinical condition. This study carried out evaluations in hospital environments at health centers in the city of Valencia, Venezuela, taking into account critical areas such as operating theatres. For sample collection, methodologies established by the Spanish Technical Standards were taken into account.
