A new horror symptom is presenting in those who have tested positive with the new Covid-19 variant Arcturus, which has now killed five people in the UK.
The Covid subvariant is skyrocketing infections in India and has prompted health officials to reintroduce mandatory mask-wearing among other measures.
The World Health Organisation (WHO) has warned that 'Arcturus', or XBB.1.16 as it is clinically referred to, is spreading across India.
