Compliance with temperature monitoring and reporting in persons who had contact with a person with Marburg hemorrhagic fever, the Netherlands, 2008*

Variable High-risk group score, mean (SD) Low-risk group score, mean (SD) p value†
Temperature monitoring week
1 4.87 (0.63) 4.25 (1.16) 0.004
2 4.87 (0.63) 3.84 (1.30) <0.0001
3 4.82 (0.68) 3.34 (1.54) <0.0001
Temperature reporting week

*Answers were given on a 5-point Likert scale, according to the following categories: 1, never; 2, seldom; 3, sometimes; 4, often; 5, always. High-risk contact, unprotected contact with the patient or her body fluids; low-risk contact, contact with the patient or her body fluids while following strict isolation measures.
†By 2-sample Student t test assuming unequal variances. Because of the relatively large sample sizes of 45 and 32 and data that consisted of scores from 1 through 5 with the indicated SDs, this test is justified by the central limit theorem and because the t distribution with 75 = 45 + 32 – 2 df is almost identical with that of a normal distribution. All p values were statistically significant (p<0.05).
