For Portugal there are two small spikes around 3/11-3/12 and 3/16 and then a big spike in IPDV between 3/28/20 and 4/1/20. On Mar 12 Portugal declared the highest level of alert following community transmission and on Mar 13th the total number cases exceeded 100. On Mar 31st the first death was announced
However when one looks at alldays instead of just weekdays the peak at 3/13/2020 does not look as prominent.Thus we are left with just the peak at the end of March and the start of April:
If one removes Portugal then there does not appear to be any significant increase or decrease in the IPDVs for the remaining countries around the times of the Covid-19 interventions in March.
