Many contagious diseases are spread through direct or indirect contact with people.
Bacteria and viruses, such as Covid-19 or coronaviruses, can be transmitted carried by microparticles of saliva that we expel when coughing, sneezing, speaking or through the contact of our hands with different surfaces.
These pathogenic elements, if a series of precautions are not followed, can access our body through our airways or mucosa, after having touched contaminated surfaces or having been in close contact with an infected person.
It is important to know the patient’s medical history, to rule out symptoms that may indicate a possible infection.
If the necessary protection measures are not taken, such as the use of masks with the appropriate protection factor, protective glasses, caps and gloves, the health professional has a high risk of contagion, being very close to the patient.
