To minimize the spread of droplet nuclei, any coughing patient with a respiratory infection – in particular, patients with or
suspected of having TB – should be educated in cough etiquette and respiratory hygiene; that is, in the need to cover their
nose and mouth when sneezing and/or coughing (see rest of the recommendation p. 12 of the guideline).
