Table 2.

The percentage of participants for each frequency of personal protective measure recommended by the World Health Organization

	N	1. Never		1. Sometimes		2. Always/Frequently
		N	%	N	%	N	%
Participants with influenza-like illnesses Facemask	139	-	-	6	4.3	133	95.7
Physical distancing	139	-	-	56	40.3	83	59.7
Hand hygiene	139	5	3.6	20	14.4	114	82.0
Surface disinfection	139	14	10.1	43	30.9	82	59.0
Avoiding crowds	139	3	2.2	48	34.5	88	63.3
Participants without influenza-like illnesses Facemask	619	1	0.2	8	1.3	610	98.5
Physical distancing	619	8	1.3	72	11.6	539	87.1
Hand hygiene	619	8	1.3	46	7.4	565	91.3

Chi square (with Fisher's exact test) was used to compare the implementation of personal protective measures between participants who had influenza-like illnesses and those who did not. There was a significant difference in the use of facemask (P=0.006), physical distancing (P<0.001), hand hygiene (P=0.004), surface disinfection (P=0.0002), and avoiding crowded places (P<0.001).
