NON-FINNISH and non-Swedish speakers have been hit the hardest by the coronavirus epidemic in Greater Helsinki, reports Helsingin Sanomat.

“They’ve had more than two times more infections relative to the size of the population group,” Asko Järvinen, the chief physician of infectious diseases at the Hospital District of Helsinki and Uusimaa (HUS), said to Helsingin Sanomat on Monday.

THL: 43 new infections

  • The Finnish Institute for Health and Welfare (THL) says the number of laboratory-confirmed coronavirus infections rose by 43 to 7,981 between Monday and Tuesday.
  • A total of 184 new infections were reported over the latest seven-day monitoring period between 16 and 22 August, signalling an increase of 27 from the period between 9 and 15 August.
  • The death toll from the new coronavirus rose by one to 335 between Monday and Tuesday.
  • Twelve people are presently in hospital care, including one in critical care, with symptoms caused by the virus.
  • The number of samples tested for the virus has risen by roughly 22,400 to 574,100 since Monday.

There are other demographic differences in the incidence and severity of infections, too. Men, for example, are over-represented in critical care admissions necessitated by the virus, accounting for two-thirds of patients in critical care in Uusimaa.

Five per cent of patients who have required hospital care have been 22–30 years old, 10 per cent 30–39 years old, 14 per cent 40–49 years old and 25 per cent 50–59 years old.

Helsingin Sanomat highlighted that the age profile of the cases has changed noticeably since last spring, as most of the recent infections have been detected in 20–39-year-olds. Young people rarely develop serious symptoms from the new coronavirus.

Under 10-year-olds, meanwhile, have accounted for around four per cent of all positive test results in Uusimaa. The share of positive test results in the age group is considerably lower than the 2.4 per cent for all test subjects, only 0.8 per cent.

“Another way to put this is that even small children can get sick from the coronavirus, but they have more diseases caused by other viruses. The number tells nothing about symptoms because many children only experience mild symptoms,” said Järvinen.

The estimate that the majority of infections cause only minor symptoms or no symptoms at all remains logical, he added to the newspaper.

“Our understanding of the share of asymptomatic carriers is derived from few sources, like [passenger] ferries. It has been possible to monitor the disease presentation more closely when people are in confined spaces,” he told. “These situations nonetheless demonstrate that many may only have budding symptoms that vanish quickly.”

Because the first few days of infections are when the carriers are most likely to transmit the virus to others, the chains of infection typically start developing early and are difficult to break in time.

Järvinen estimated that the causes of symptoms experienced at different stages of the disease can vary: the early symptoms are probably caused directly by the viral infection, whereas the later worsening of symptoms may be an indication of a strong immune response.

“People usually seek hospital treatment after having the disease for roughly a week, which means it may be because of a too strong immune response,” he told.
