Coronavirus death toll has now exceeded 100,000 worldwide, a figure that adds a sense of scale to COVID-19’s virulent effects. Ongoing research shows that the risk is not equally divided out, however. In fact, there is a gulf between people with certain pre-existing health conditions and those with none at all.
Health bodies have outlined a number of health conditions that raise your risk of developing severe complications from catching COVID-19.
A recent study conducted on 1,600 hospitalised patients in China has advanced the effort to understand more about those most at risk.
The research, which analysed information for 1,590 hospitalised patients between December 2019 and January 2020, found the risk to be highest in people with cancer.
Those with a tumour had a 250 percent increase in adverse outcomes.

The study also found that patients with two or more comorbidities were at a far greater risk of falling critically-ill, compared with those who had a single comorbidity, and even more so as compared with those without.
Eight percent of the hospitalised patients had two or more conditions.
Writing in the European Respiratory Journal, the authors said: “Among laboratory-confirmed cases of Covid-19, patients with any comorbidity yielded poorer clinical outcomes than those without. A greater number of comorbidities also correlated with poorer clinical outcomes.”
The findings are consistent with previous studies.
One of the first studies to assess the risk of COVID-19 in vulnerability groups was in February.
The study, which used data from more than 72,000 patients, found heart disease to be one of the gravest indicators.
Heart disease, a number of conditions characterised by narrow or blocked blood vessels, accounted for 10.5 percent of COVID-19-related deaths.
Six percent of patients with high blood pressure also died.
