LONDON -- Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild. In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central African Republic and Angola. Seven countries elsewhere in Africa have similar outbreaks and cases have been reported in Asia. Of the two countries where polio remains endemic, Afghanistan and Pakistan, vaccine-linked cases have been identified in Pakistan. In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks.

COVID, the respiratory disease caused by the new coronavirus, has spread to every continent except Antarctica. Not too long after the virus was first discovered at the end of December, labs turned their sights toward treatment. Currently, however, there is no cure for this coronavirus, and treatments are based on the kind of care given for influenza seasonal flu and other severe respiratory illnesses, known as "supportive care," according to the Centers for Disease Control and Prevention CDC. These treatments essentially treat the symptoms, which often in the case of COVID involve fever, cough and shortness of breath. In mild cases, this might simply mean rest and fever-reducing medications such as acetaminophen Tylenol for comfort.
