Research into 355 deaths found that only three of the victims, 0.8 per cent, had been clear of illnesses before they were infected.
Nearly half of them – 48.5 per cent – already had three or even more health conditions before they were diagnosed with Covid-19.
Another 25.6 per cent had two other ‘pathologies’, while 25.1 per cent had one.

The research by Italy’s National Institute of Health is consistent with previous findings that people with existing illnesses are more likely to die from coronavirus. According to the study, the most common of these problems in Italy include high blood pressure, heart disease and diabetes.
Some 76.1 per cent of the patients who died of Covid-19 had previously had problems with high arterial blood pressure, the study found. More than a third – 35.5 per cent – had diabetes, while 33.0 per cent had suffered from ischemic heart disease.
Nearly a quarter, 24.5 per cent, had suffered from atrial fibrillation.
According to a study in the journal Immunology Research, high blood pressure causes low-level damage to the insides of blood vessels and the damage stimulates a small response from the immune system meaning that, when it has to respond to a real threat like a viral infection, there is a greater risk of it overreacting.
Immune overreaction can lead to sepsis or organ failure, which are often fatal, and are known to be a cause of death among coronavirus patients.
The Italian study also found that the average age of people who died from the virus in Italy was 79.5, although it was slightly higher for women than men. That is also consistent with previous findings from around the world that older people are more vulnerable to the disease.
Italy’s population is the second-oldest in the world, after Japan’s, and the country has suffered the worst outbreak in Europe by far.
