   2 <p>
   3   Rnaught is an R package and web application for estimating the
   4   <a href="https://en.wikipedia.org/wiki/Basic_reproduction_number" target="_blank">basic reproduction number</a>
   5   of infectious diseases. For information about using this application, view the

  13 <h4>What is the basic reproduction number?</h4>
  14 <p>
  15   The basic reproduction number, denoted <em>R</em><sub>0</sub>, is defined as the expected number of infections caused
  16   by a single infectious individual when introduced into a totally susceptible population. It assumes that all
  17   individuals in a given population are susceptible to the disease, and that no preventive measures (such as lockdowns
  18   or vaccinations) have been enforced. It is a useful indicator of the transmissibility of an infectious disease during
  19   the early stages of its spread and detection.
  20 </p>
  21 <p>
  22   If <em>R</em><sub>0</sub> &lt; 1, the disease will eventually die out. On the other hand, if
  23   <em>R</em><sub>0</sub> &gt; 1, the disease will spread (the higher the <em>R</em><sub>0</sub>, the faster this will
  24   happen). Due to uncertainty of known data about the disease, it is difficult to determine <em>R</em><sub>0</sub>
  25   precisely. Therefore, many estimation methods exist, each based on different assumptions and yielding different
  26   estimates. It is the responsibility of users to employ the most appropriate estimator (or suite of estimators) given
  27   the situation at hand.
