Europe is deep in the second wave of the coronavirus epidemic, and a particularly worrying trend is beginning to emerge: More older people are becoming infected.

Over the summer months, the continent saw infection clusters popping up mostly among younger people who were venturing out into bars, restaurants and other public spaces. While that wasn't ideal, it meant the death rate stayed relatively low, since younger people are statistically less vulnerable to the virus and most avoid getting seriously ill.

However, the European Centre for Disease Prevention and Control (ECDC) has warned that more older people are now becoming infected. According to the ECDC's latest situation report, at least 13 countries in Europe saw new infection rates among people aged 65 or over rise to what ECDC defines as "high" last week -- between 64 per 100,000 in Croatia and 206 per 100,000 in the Netherlands.
