It pointed out that Covid-19 patients suffering from Category 4 or 5 symptoms have increased from 6.7 percent in January to 35.2 percent in April. Category 1 and 2 patients suffer milder symptoms, Category 3 ones develop some form of pneumonia but can still breathe on their own, those in Category 4 need oxygen supply while Category 5 patients need a ventilator to breathe. The ministry attributed this to younger people seeking treatment late and also the proliferation of new Covid-19 variants.
