Example contact number concepts for epidemiology students

Contact numberAverage contacts per person per day · Multiplied by transmission chance per contact · Feeds into the basic reproduction number

Contact tracingIdentifies people exposed to a confirmed case · Usually covers a set window before symptoms · Contacts are notified and monitored

Mixing patternsHousehold contacts differ from school contacts · Age groups mix at different rates · Contact matrices capture these differences

Herd immunity thresholdDepends on the reproduction number · Calculated as 1 minus 1 over R0 in simple models · Lower R0 means a smaller immune share is needed

Contact survey methodsDiaries record daily encounters · Proximity sensors estimate close contact · Surveys must account for recall bias

DeckOwl turns your own material into a mind map, so the useful work happens in the content rather than in the layout.

Frequently asked questions

What is a contact number in epidemiology?

It usually means the average number of people one person meets in a given period, and it is a key input for estimating how fast an infection can spread. Multiplying it by the chance of transmission per contact gives a basis for the reproduction number.

How do I map contact numbers for an outbreak study?

Start with a contact matrix that splits people into age groups or settings such as home, school, and work. Then map how often each group mixes, and check the assumptions against survey data.

Can I export my mind map?

Export is a paid feature, and the Plus plan includes PDF and DOCX export. The free plan lets you study the map in the browser without exporting it.

Where can I get help with my DeckOwl account?

Use the contact options on the DeckOwl website for account, billing, or technical questions. This page covers the product and does not list a separate phone line.
