Time trend of Coronavirus Covid-19 in Italy

Data updated at 20-09-2020.

The most recent remark is on July 6th, 2020.

This article reports the temporal trend of the data of the Italian Ministry of Health released by the Civil Protection, related to the COVID-19 epidemic that has hit Italy since February 2020.

Graphical analysis

Below is a graph composed of two zones. The upper zone draws the time series of cumulative data relating to the epidemic. Here I show, day by day:

  • the numbers of infected cases (positive);
  • those, unfortunately, deceased;
  • the healed;
  • and, finally, the total numeber of cases: infected+healed+deceased.

The lower area graphically shows, day by day, the trend of the variation of positive cases. The abscissas of the zones are aligned. Thereby it is immediate to compare the trend of the slope of the line of positive cases present in the upper area, with the difference of the cases, reported in the inferior area.

COVID-19, Italy

Hereafter the numbers for the last day detected. The columns indicate [1]:

  • date, the date of the day;
  • overall hospit., the number of positive cases hospitalized;
  • quarantine at home, the number of positive cases in home isolation, with mild or no symptoms;
  • positives, the sum of the positive cases: hospitalized+quarantine;
  • change of positives, the variation of the sum of the positive cases between the current and the previous date; this is not a cumulative data;
  • new positives, the new positive cases at the current date; this is not a cumulative datum;
  • healed, the number of patients healed;
  • deceased, the number of deceased patients;
  • overall cases, the total number of cases: positive+healed+deceased.

Finally, below I report the temporal trend of new daily cases regarding the overall country.

COVID-19, Italia, regioni, andamento temporale nuovi casi giornalieri

This chart is the one checked by ISS experts to understand the trend infection. And based on this they tell us that we have passed the peak of the contagions. What does this statement mean? The daily number of new ones contagion is the speed of spread of the infection. For infections it is observed that the diffusion speed has a trend that recalls that presented from this graph, taken from this wikipedia article:

pandemic

Having exceeded the peak means having overtaken the maximum of the graph, and proceed towards ever lower diffusion rates.

In the previous graph we see the theoretical effect of containment, which allows to postpone the peak and to lower it: the aim is not to decrease the number of affected people [2], but to dilute the time expansion to prevent healthcare facilities from going into crisis.

Unfortunately, the actual course of an infection is quite different from that of a theoretical curve, and it is influenced by many factors. First among all the possibility of contrasting the diffusion. And that's what we're looking at in our real trend of new daily cases. It is quite difficult to see a similarity with the curve above. Above all, the trend of cases after the peak does not seem to decrease as indicated by the theoretical model. Rather, there is the sensation of assisting at a very slow decrease with a linear trend.

Some remarks

The most recent observations precede the temporally older ones.

[July 6th, 2020]. After a long pause, I add a note at a delicate moment.

From June the 3rd, in Italy we are experiencing the almost complete reopening of the activities. Also, up to two days ago, we observed a slow but steady one decrease in positive cases.

But in the last two days the trend of positive cases has reversed. We deals with modest figures. The national figure yesterday was +21, and today it is +67. But it is a fact that the curve the positives started growing again. It is not good news.

I believe that the current "isolates the outbreak" policy requires a lot of effort, and an extensive asymptomatic screening campaign. Campaign that in Italy we have never been implemented. If this is also associated with the lack of controls by the police about spacing and hygiene rules (mask and clean hands), the result cannot be positive.

An observation regarding the region Lazio. Today it arrived to count 870 positive cases, of which 212 hospitalized. While the number of hospitalized is comparable with Lombardy, the number of positives is approaching a thousand. And this is aligning Lazio with regions such as Piedmont (1208 positive) and Emilia-Romagna (1064 positive). If I were Zingaretti (the current Governor of the region, secretary of the Democratic Party) I would worry and look for ways to pay more attention to the problems of the region he should govern.

[July 6th, 2020 - end]

[April 12, 2020]. Government continues to tell us that things are constantly improving. The fact is that they tend to present best data from time to time. Once upon a time it is the low number of death. The day after a lesser gain of positives. And the next day, the decrease of the hospitalized. This way of doing has the purpose of avoiding the spread of discouragement. But in this way people lower their guard and they do not respect the containment rules.

We can see the result in our charts. Meanwhile we reached the peak of new daily infections (over 6500) on March 21, twenty days later we still have almost 4700 new cases of infection every day. The descent rate is very slow.

Let's face China. In that case one month after the start of the lockdown, the curve of the total cases had definitely changed its shape, decreasing the slope to clearly start the expected flattening. Flattening indicating zero new infections.

In Italy, one month after the introduction of the lockdown, which took place on March 9, the curve of total cases still points decidedly upwards. Obvious sign that the measures in place are unable to block the spread of the virus in a few weeks.

This observation also applies to the United Europe as a whole. With the difference that Italy began the lockdown much earlier than the other EU countries. Indeed, one month after the outbreak of the infection in Europe, some of these countries do not have yet imposed the lockdown. So in theory now we should be much better. Theory that I do not see come true in practice.

I think the keystone is to isolate asymptomatic positives. In Italy we are not implementing a strong positive quarantine policy. While in China these were removed from their families. Here this does not happen. Consequently, a new positive in Italy almost certainly equates to contagion of an entire family.

[April 12, 2020 - end]

[March 30, 2020]: maybe finally we can hope. Looking at the chart below, we note that the variation of the positives (the bottom rectangle) is decreasing for 9 days, except for a sudden single increase on March 25th. Statistically, we can hope that the lockdown is finally producing effects to contain the outbreak.

[March 30, 2020 - end]

[March 18th 2020] About the national trend, I feel the need to remark the following fact. Various sources of information are using the general total of daily data of the Ministry of Health to account for the change in the epidemic.

This number indicates the total number of people affected by the virus, adding three different groups: sick, healed and deceased. This quantity give us an idea of ​​the overall impact of phenomenon. It can only increase. And when all this ends, it will take on a fixed value: constant, equal to the maximum value reached. The slope of this curve (i.e. its daily variation, used by many news media) tells us if the speed with which the virus impacts the country as a whole decreases. But it is not the right indicator to measure the virulence of the infection.

The data relating to each of the aforementioned groups are precious. The analysis of each of these classes tells us something about how we are dealing with the epidemic. For example, observe how it varies the number of people healed per day, after a few weeks, can tell us how the therapies adopted are effective.

But the total of these three quantities is much more articulated, and if the analysis is not pointig in the right direction, it gives us misleading indications. Remember the concept of adding apples with pears, who taught us in elementary school? It is just that.

To understand the progress of the infection, it is necessary to analyze the size of the group formed by infected people, and only these. The healed and the deceased are no longer infected. Both of these cases are defeats for the virus, which is not more able to propagate using them as vectors.

The size of the group of infected people is the red line in the upper box of the national trend. To observe the variation of the slope of this curve is particularly important: it tells us the speed of spreading the virus.

Even just the total number of infected people (note: not the total of people affected: infected + healed + deceased) is complex to analyze. Consider the fact that every day the other two classes (heale and deceased) contribute to this measure: they subtract to the number of infected. While the number of new positives adds up. The slope of the total of infected people is the result of these three quantities, antagonistic to each other.

I find misleading the term new_currently_positive that Civil Protection uses in its data tables. In my data analysis I call this column change of positives because it is the difference between the total of the positives of the day and the total of the positives from the previous day.

The number of people joining the positive group for the first time, also known as the new currently positive, can be calculated by adding to the changes of positives the number of people who left the group: the people healed during the course of the day and the deceased during the day. If you do this operation, in this period there is a notable increase in new positives compliance with the provisions of the Civil Protection.
