But with the resumption of exchanges among the younger generations, it is gastroenteritis and colds, which have disappeared thanks to recurring confinements and remote courses, which are making a comeback even if the level of activity is still well below Those who usually observe around this time.
Relaxation of barrier gestures

Twice as many gastros and rhinos in a few weeks
In our region, the incidence rate of gastroenteritis thus jumped from 50 to 121 cases / 100,000 inhabitants between the 1D and the 2e week of September. He has since come down (112 the 3e week and 68 last week) but could well see a rise insofar as the trend is rather a continuous increase in France (85/100 000).
For acute respiratory infections (colds, rhinos, sore throats), the rate rose from 49 to 80 between the 1D and the 2e week of September. It was 73/100 000 the last week equivalent to the national rate (76/100 000).
