Biomaths in times of coronavirus

Since the outbreak of the coronavirus disease 19 (COVID-19), many mathematical models have been proposed, various of which several governments have used to implement their policies to lock down the population. In particular, Mexico City has posed for an ordinary differential equations model to control the spread of the virus. But, no optimal span of the lockdown was proposed, and therefore, the city is in an indefinite quarantine, affecting the whole country’s economy.
