Document Summary

The number of infected cases are small, but the number of deaths are high. The e(cid:271)ola (cid:448)irus has (cid:272)oe(cid:448)ol(cid:448)ed (cid:449)ith the (cid:271)at a(cid:374)d it does(cid:374)"t (cid:272)ause that (cid:373)u(cid:272)h da(cid:373)age to the (cid:271)at.

For a lot of pathogens, replication within a host is associated with transmission between hosts. As we infreace relication rate in the host, we increase transmission rate. Increasing replication rate might increase transmission rate, but it will decrease the days of how long the infection lasts.
