Coronavirus infection rate may shift toward younger ages

Death risk higher in cancer patients

As the coronavirus infection rate in Washington State passed its peak, cases in people over age 60 fell 10%, while infections among younger age groups rose steadily, researchers say. The nation's first known major outbreak took place at a nursing home in the state. Later in the outbreak, however, infections rates among those under age 40 increased from 20% to 40% of total cases, according to a report posted on Thursday without peer review on the medRxiv preprint server. "The fact that young people do not usually get as sick as older people and people with comorbidities is a double edged sword," co-author Dr Henry Kaplan of the Swedish Cancer Institute in Seattle told Reuters. "It also means that they are often unaware that they have the disease or unaware of the risk that they pose to others. As a result, there is a natural tendency to be lax about distancing, masks, and other precautions... While the younger patients will usually do fine with the disease, we need to ensure that they don't become the dominant vector in spreading it."
Cancer patients who contract COVID-19 are at increased risk of dying within a month, new research shows, and treatment with a combination of malaria drug hydroxychloroquine and the antibiotic azithromycin may contribute to that added risk. Among 928 adults with COVID-19 and active or previous cancer, 13% died within 30 days of their coronavirus diagnosis - twice the roughly 6.5% rate seen among all infected patients worldwide, Dr. Jeremy Warner of Vanderbilt University in Nashville said on Thursday at the American Society of Clinical Oncology (ASCO) annual meeting, held virtually this year. Patients with progressing cancer were roughly five times more likely to die within 30 days than those in remission or with no evidence of disease. Other factors tied to a higher risk of death included older age, male gender, former smokers, additional illnesses, and use of hydroxychloroquine with azithromycin.
However, the researchers emphasize other factors, such as how severely ill those who received the drugs may be, make it difficult to draw conclusions about their impact on the death rate. Neither the type of cancer, the therapy used to treat it, or recent surgery were associated with increased death risk, however, suggesting that certain treatments could continue during the pandemic "with extreme caution," Warner's team wrote on Thursday in The Lancet. "These findings have implications for patients and healthcare providers who will be confronted with difficult decisions during the (coronavirus) pandemic, such as whether to withhold or continue anticancer treatments, and whether to accelerate end-of-life planning under some circumstances."
A large study from France helps quantify the risks faced by people with diabetes and coronavirus infection. Among 1,317 hospitalized COVID-19 patients with diabetes, roughly one in 10 died within seven days and nearly a third required a ventilator for breathing assistance or died in that period. Fewer than one in five could be discharged within a week. The average patient in the study was age 70, and most had type 2 diabetes, researchers reported on Friday in Diabetologia. Poor outcomes were more common when patients were older, had diabetes complications or were overweight. While long-term blood sugar control was not linked with COVID-19 severity, being overweight was independently associated with the risk for needing mechanical ventilation or dying within seven days. Type 2 diabetes has long been associated with obesity. "Special attention" should be paid to protecting overweight elders with diabetes complications from "contamination" with the coronavirus, the researchers said. (https://bit.ly/2Apm4zO).
