 <h4>What is the basic reproduction number?</h4>
 <p>
-  The basic reproduction number, denoted <em>R<sub>0</sub></em>, describes the expected number of infections caused by a
-  single infectious individual. It assumes that all individuals in a given population are susceptible to the disease,
-  and that no preventive measures (such as lockdowns or vaccinations) have been enforced. As such, it is a useful
-  indicator of the transmissibility of a disease during the early stages of its detection.
+  The basic reproduction number, denoted <em>R</em><sub>0</sub>, is defined as the expected number of infections caused
+  by a single infectious individual when introduced into a totally susceptible population. It assumes that all
+  individuals in a given population are susceptible to the disease, and that no preventive measures (such as lockdowns
+  or vaccinations) have been enforced. It is a useful indicator of the transmissibility of an infectious disease during
+  the early stages of its spread and detection.

 <p>
-  If <em>R<sub>0</sub></em> &lt; 1, then the disease will eventually die out. On the other hand, if
-  <em>R<sub>0</sub></em> &gt; 1, the rate at which the disease spreads is exponential. Typically, it is difficult to
-  determine <em>R<sub>0</sub></em> precisely, due to uncertainty in information relating to the spread of the disease.
-  Therefore, many estimation methods exist, each based on their own models and yielding different estimates. It is the
-  responsibility of public health officials to employ the most appropriate estimator given the situation at hand.
