Italy's R0 value is now officially above 1, again. This is what you get when people misbehave even though the regulations were (and are) good enough to reduce the infection rate to a minimum.
Actually, new daily cases are so low that Rt increasing above 1 is likely to be caused by statistical fluctuations... for now

Moreover, 30% of the new daily cases are caused by people coming from abroad (and illegal immigrants are only a very small part of this).
For foreigners, nationwide news talked a lot about an enterpreneur returning in Veneto region from Serbia with COVID-19 symptoms. He was tested positive and, despite worsening conditions, he refused to be hospitalized. Not only he returned to work, but he attended a party and a funeral service. Ultimately, he worsened so bad to require intensive care. Luckily, this cluster seems to have been contained quickly and efficiently.
[...] willfull blindness that caused Italy's health sector to crash around that date.
I do understand that the details on how coronavirus spread here may be difficult to get for a foreigner, because they require some basic knowledge of the country itself, but that one line seems to imply that the entire nation's healthcare system has been overwhelmed by Covid-19 at various stages. It wasn't. There are twenty regions in this country, and only one (maybe two, depending on criteria) of them got hit very, very hard. These regions are densely populated but they represent at best one fifth of the entire country in terms of population. And there have been areas within these regions that experienced Covid-19 in a much less catastrophic way.
Other regions, including my own, sent their own doctors to help and I don't recall any articles saying that ICUs were overwhelmed from Emilia Romagna southwards. There is a raging debate about very expensive makeshift hospitals, built and set up very quickly, that served no real purpose at all. We even hosted two patients from other regions because we had extra space in our own hospitals. An Air Force C-130 transferred these extra patients here (I still have the videos in my phone, recorded right from the tarmac).
For foreigners, it is also worth noting that, unlike the rest of the country, Lombardy has quasi-private healthcare (unsurprisingly, the governor who made this reform was found to be heavily involved in bribery scandals). Many hospitals are privately-managed, and focus more on specialist services than general medicine, and have comparatively few ITUs.
Lombardy and Veneto regions discovered their first clusters the same day, but Veneto healthcare system started a massive screening campaign in order to contain the outbreak, while Lombardy healthcare system did not even stock up supplies considering it a waste of money.
When the 2nd Lombardy cluster was found in an hospital near Bergamo, the hospital was closed only for few hours and then reopened. Moreover, the Italian industrial employers federation strongly advised against locking down the valley with the newly found cluster to avoid closing major industries in the area. This backfired, spreading the virus and leading to nationwide lockdown.
In an attempt to trace back the arrival of the virus in Italy, compatible virus traces were found in sewage waters in Milan, Turin and Bologna as early as December 2019, and the hospital near Bergamo epicenter of the outbreak reported having ~100 unusual cases of "pneumonia of unknown origin" in the same time frame. They are still investigating whether they were already COVID-19 cases.
