People diagnosed with cancer more than 24 months ago are more likely to get severe Covid-19 infection, according to researchers. For the study, published in the journal Frontiers in Oncology, the researchers analyzed the case of 156 cancer patients with confirmed Covid-19 diagnosis in London. Patient follow-ups, conducted 37 days later, found 22 percent of patients from the cohort died from Covid-19 infection. Patients of the Asian ethnicity and those diagnosed with cancer over 24 months before the onset of Covid-19 symptoms were at higher risk. Patients with dyspnoea (shortness of breath) or high CRP levels (a common blood marker of inflammation) were also at higher risk from Covid-19. Severe Covid-19 infection was associated with fever, dyspnoea, gastrointestinal symptoms, or those with cancer.
