A control approach to the Covid-19 disease using a SEIHRD dynamical model	2020-05-30		.txt	text/plain	6320	382	60	The recent worldwide epidemic of Covid-19 disease, for which there is no vaccine or medications to prevent or cure it, led to the adoption of public health measures by governments and populations in most of the affected countries to avoid the contagion and its spread. α and β are the probability of disease transmission in a single contact with exposed (infected) people times the average daily number of contacts per person and have units of 1/day. We propose the use of control theory to determine public nonpharmaceuticals interventions (NPIs) in order to control the evolution of the epidemic, avoiding the collapse of health care systems while minimizing harmful effects on the population and on the economy. Therefore, the control action needs to be calculated as a function of the number of infected people I (the number of exposed people E is quite unknown) in order to avoid future hospitalization requirements in the next 10.6 days at most.	./cache/cord-330956-692irru4.txt	./txt/cord-330956-692irru4.txt
