Coronavirus infection almost always enters the family through adults, says Timo Lukkarinen, Director of Helsinki Health Centers at Helsingin Sanomat. Lukkarinen is responsible for tracing the exposed in Helsinki. According to him, quite often the whole family falls ill, but not nearly always. At home, adults are most likely to infect each other. Some children can get sick and some stay healthy.

Lukkarinen tells HS that it is impossible to determine with whom all children have been in close contact in kindergartens and schools. Children are often so mildly symptomatic that their infections are not detected. For example, no clusters of infection were detected in Helsinki and Vantaa when the schools were still open.

Adults, on the other hand, have significantly more infections in those occupational groups where teleworking is not possible. There are more than 200 infected people working in social work and health care in Helsinki.

The number of infections in the social and health sector has not been overemphasized in relation to other working-age people, Lukkarinen says in the newspaper. Instead, the construction industry is a surprising risk area in the Helsinki metropolitan area. There have been clusters in Vantaa, especially in the gangs of foreign builders living in busier rooms. One infestation was also found on a construction site where workers did not live or spend their free time together.

The infected people have worked in Helsinki, for example, in a pharmacy, cleaning service, kindergarten, bank, transport company, shop, bakery, plant maintenance, restaurant and university. Due to the large number of customers, grocery stores have been suspected of being at risk, but the employees of the stores do not appear particularly in the statistics. Lukkarinen, who was interviewed by HS, estimates that it is safe to do business in stores if he takes care of hand hygiene and maintains safety distances.
