mers_2014_15: Data on Middle East Respiratory Syndrome (MERS) in Saudi Arabia.

Description

This data set gives:

1. the daily incidence of onset of symptoms of laboratory confirmed human infections with MERS-CoV in Saudi Arabia between the beginning of July 2014 and the end of December 2015, and

2. estimates of the mean and standard deviation of the serial interval for MERS.

Format

A list of two elements:

• incidence: a dataframe containing 495 days of observations with dates in the first column, and number of local (2nd column) and imported (3rd column) cases of MERS,

• si: a list of estimates of the mean (mean_si) and standard deviation (std_si) of the serial interval for MERS.
