Some observations (opinions...) Don't do what Italy did. Don't do what Spain did. The UK ignored what is happening in Italy, lookout Loretta.
Around the globe plenty of people in the 40 to 65 year old age range are requiring weeks of intensive care with respirators to beat this virus. Hospitalization is required in more than 10% of the cases. Huge strain on the system. In Italy 8% of the healthcare workers are infected, and young healthcare workers are dying. A herd immunity policy will fail miserably - too many in the herd will die slowly or recover slowly destroying the healthcare system.
Wuhan went 'draconian' and they appear to have it on the run. China kept people locked down until they tested negative. With closed borders Jamaica has a chance at slowing the spread if they can keep people from spreading the virus for a few weeks. Social-distancing in Italy is starting to have an effect, after 2+ weeks.
Be safe people!
