Few things have been able to dominate headlines for weeks at a time, but then, the world hasn't seen the outbreak of a disease like the novel coronavirus, COVID-19, in quite some time. Its spread has been rapid and in China, which has been hardest hit by far, the government is treating its threat with the utmost gravity, locking down tens of millions of people and instituting travel bans, among other measures intended to slow the disease's spread.
Outside China, however, governments are trying to walk a tightrope between preparing their citizens for the potential of a wider outbreak without encouraging outright panic.
