Mexico City, Jul 10, 2021, SPA -- Mexico is entering its third wave of the coronavirus pandemic, as infections rose by 29% compared to the previous week. Authorities said the relative decline of serious cases among older people is a result of the country's vaccination campaign, which as of Friday has given at least one dose to about 39% of all adults. The Assistant Health Secretary said the rise in infections is not due to the arrival of the Delta variant, but rather to an increase in public activity. Mexico City health authorities said they expect the third wave to peak in August in the capital, which has been the worst hit by COVID-19 in the previous two waves, AP reported. --SPA 12:23 LOCAL TIME 09:23 GMT 0011 www.spa.gov.sa/w1583170
