Bromley public health calendar of bugs

The calendar gives information on some of the bacteria and viruses that produce the highest number of infectious diseases throughout the year.

Be aware of what bugs are most common at certain times of the year and the symptoms to look out for. 

With every bug described in this calendar the standard principles of infection prevention and control remain the same: hand hygiene, covering nose and mouth when coughing or sneezing (Catch it, Bin it, Kill it!), fresh air and ventilation, and keeping the environment you live or work in clean.

You can download the Calendar of Bugs 2023 (PDF 18.63 MB) to print out for yourself at home.

A version of the document with just the bug information is also available to download and print Bugs key facts (PDF 22.29 MB)
