Across the world we are seeing Coronavirus infections rise in law makers and politicians in different countries. At least two politicians have already died of the Coronavirus in Iran, where at least 8% of the parliament is infected. A member of France’s National Assembly was hospitalized. A Ukrainian lawmaker has isolated himself after meeting with the above referenced French lawmaker. Two cases of the Coronavirus have also been confirmed in Brussels at the EU.
In the U.S., we already have the incoming White House chief of staff, Sen. Ted Cruz, Rep. Paul Gosar, Rep. Doug Collins, and Rep. Matt Gaetz who have all self-quarantined after coming into contact with a person infected with the Coronavirus at CPAC 2020 where President Trump and VP Mike Pence also attended. We also have Rep. Julia Brownley closing her office in D.C. and working remotely after meeting with a person in D.C. last week who tested positive for COVID-19.
If something were to happen to either the President of VP, the following is the current line of succession for the President of the U.S.:
No. Office Current officer
The U.S. government also has a Continuity of Operations plan in place for itself, while FEMA would provide guidance to the private sector for business continuity planning purposes. At least for the immediate future you do not have to worry about the loss of government function, but all the same you should be prepared.
