The current conglomerate analysis for week 42 (from October 12 to 18) of the AGES Infection Surveillance and Epidemiology department shows, in addition to a slight accumulation in the free time area, more serious cases in the elderly and residences.
As of October 23, 39,504 cases out of a total of 75,439 could be assigned to one of the 7,507 groups.
644 groups of households discovered
An example from Styria in the current analysis shows a nursing home employee as the first case, follow-up infections in five colleagues, eleven residents, and a family member of an employee resulted in the group. However, the health / social area is lower than the previous week and fell from eleven to 8.5 percent. The family environment continued to be the most extensive: with 644 conglomerates, this sector has a participation of almost 60 percent (it went from 53 to 58 in one week) and, therefore, 1,691 of the 4,055 cases are assigned to this environment.
Unknown source for household groups
In the household group, in which members infect each other, little can be done to combat the spread of the virus, as the source of the virus is unknown. Therefore, it is important to start early, as AGES epidemiologist Daniela Schmid emphasized on several occasions. For example in the leisure area, where the proportion is 25 percent and 1,000 cases per week.
36 people infected with corona after a birthday party in Lower Austria
Two new examples from the KW32 entertainment environment show groups appearing at a birthday party in Lower Austria and another in Styria. There the party ended with 36 infected teenagers between 18 and 20 years old. In the course of contact tracing by authorities, the original figure of five to six people was refuted. More corona infections in a school followed by three classmates who could at least have been at the party and with a teacher and in the families of the party guests.
A case from Styria resulted in a group of 17 people in a football club after a sociable round on the club premises: one player with already mild symptoms was enough for both players from the fight team, the reserve team and a The women’s team player became infected, a clear indication that the transmission did not occur during the football game itself, said in the AGES analysis.
Cluster analysis is a fundamental tool for the Crown Commission; According to the WHO, a cluster is defined by an accumulation of cases by time or place or an accumulation of cases that are characterized by a common exposure, for example a joint trip – the known travel clusters of the Summer, or attending an event of leisure, that is, celebrations or parties. Depending on its origin, the weighting of a cluster affects the recommendation of the Corona Commission to change the traffic light.
