What is the new COVID-19 variant and should we be concerned ?

A new COVID-19 variant spreading fast in the United States and parts of Europe is leading to concerns about a surge in infections but experts say the strain, while highly contagious, does not appear to make people sicker. According to WHO, there is no indication that it is more severe than previous versions of Omicron. Scientists are continuing to gather data and analyze XBB1.5, but major concerns will only arise if the sub-variant changes in behaviour and leads to widespread and more serious symptoms.Those infected can expect to experience symptoms including runny nose, sore throat, cough, headaches and fever. WHO believes that vaccination continues to be the key to protect against the latest strain.
