In a media briefing on Wednesday, World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus spoke of a new sub-variant of the highly transmissible Omicron variant of COVID-19 that has now been detected in India.The WHO chief also shed light on the sudden spike of coronavirus cases worldwide. “Globally reported cases have increased nearly 30 per cent over the past two weeks. Four out of six of the WHO subregions saw cases increase in the last week," he said. "In Europe and America, BA.4 and BA.5 are driving waves. In countries like India a new sub-lineage of BA.2.75 has also been detected, which we're following," he added. Given that the global health agency has come forward to lay emphasis on the situation, it is important that we take necessary precautions to curb the spread of the virus. With the change in seasons and monsoon bringing in several other viral infections, it could become difficult to tell the symptoms apart. However, if you develop a sore throat, experts believe the duration of your symptom could reveal whether you have COVID-19 or not.Also read: Warning signs of a heart attack that may be misunderstood as indigestion
