Italian researchers are looking at whether a higher than usual number of cases of severe pneumonia and flu in Lombardy in the last quarter of 2019 may be a signal that the new coronavirus might have spread beyond China earlier than previously thought.

Adriano Decarli, an epidemiologist and medical statistics professor at the University of Milan, said there had been a “significant” increase in the number of people hospitalized for pneumonia and flu in the areas of Milan and Lodi between October and December last year.

He told Reuters he could not give exact figures but “hundreds” more people than usual had been taken to hospital in the last three months of 2019 in those areas - two of Lombardy’s worst hit cities - with pneumonia and flu-like symptoms, and some of those had died.

Decarli is reviewing the hospital records and other clinical details of those cases, including people who later died at home, to try to understand whether the new coronavirus epidemic had already spread to Italy back then.

“We want to know if the virus was already here in Italy at the end of 2019, and - if yes - why it remained undetected for a relatively long period so that we could have a clearer picture in case we have to face a second wave of the epidemic,” he said.

The World Health Organization has said the new coronavirus and COVID-19, the respiratory disease it causes, were unknown before the outbreak was first reported in Wuhan, in central China, in December.

Decarli said once his research was concluded, local health authorities might decide to request authorisation to exhume bodies of people with suspect symptoms.

Other experts cast doubt on the hypothesis that the new virus could have been circulating in Europe before the end of 2019.

“I think it extremely unlikely that the virus was present in Europe before January,” said Paul Hunter, a professor in medicine at Britain’s University of East Anglia who has been tracking the evolving pandemic.

Hunter said that unless Italian scientists get positive results from samples taken and stored at that time, then the suggestion should not be given credence.
