E' una revisione della letteratura del 2005, molto interessante, anche se fa riferimento a dati un po' vecchi,comunque i concetti fondamentali sono:
-"...data suggest that risk of disease transmission to other symptom-free passengers within the aircraft cabin is associated with
sitting within two rows of a contagious passenger for a flight time of more than 8 h.
This association is mainly derived from investigations of in- flight transmission of tuberculosis, but is believed to be relevant to other airborne infectious diseases.Some variation in this association has been reported, with one outbreak of severe acute respiratory syndrome (SARS) in which passengers seated as far as seven rows from the source passenger were affected " (questa è vera sfortuna: shock: )
Comunque:
-"The risk of disease transmission within the confined space of the aircraft cabin is difficult to determine" ( ci sono pochi studi al riguardo)
Fortunatamente,
-"In general, HEPA filters used on commercial airlines have a particle-removing efficiency of 99·97% at 0·3 microns.These filters remove dust, vapours, bacteria, and fungi. HEPA filters also effectively capture viral particles because viruses usually spread by droplet nuclei"
Uso delle maschere:
-"Although masks play a crucial part in infection control in health care settings, their use is unproven in disease control within the aircraft cabin"
E soprattutto:
"In addition to the flight crew, public health officials and
health care professionals have an important role in the management of infectious diseases transmitted on airlines and should be familiar with guidelines provided by local and international authorities"
Quindi se avete bisogno di un'infermiera a bordo, sono a disposizione...
