Notes
1,These statistics refer to infections occurring in private households.
2,"The ratios presented are rounded to the nearest 100 if over 1,000, to the nearest 10 if under 1,000, and to the nearest 5 if under 100. This may result in credible intervals which appear to be similar to the estimated average ratio."
3,"All estimates are subject to uncertainty, a credible interval gives an indication of the uncertainty of an estimate from data analysis. "
4,"These ratios do not represent a person's risk of becoming infected, since risk of infection depends on a number of factors such as contact with others or whether a person has been vaccinated. "
