July 30 (Reuters) - The war against COVID-19 has changed because of the highly contagious Delta variant, the U.S. Centers for Disease Control (CDC) said, proposing a clearer message, mandatory vaccines for health workers and a return to universal masking.
DEATHS AND INFECTIONS
* Eikon users, see COVID-19: MacroVitals https://apac1.apps.cp.thomsonreuters.com/cms/?navid=1592404098 for a case tracker and summary of news
* The European drugs regulator approved a ramp-up in production of active substances used to make COVID-19 shots at Moderna's sites in the United States.
* Germany will require all unvaccinated travellers arriving in the country from Sunday to present a negative COVID-19 test result.
* The highly contagious Delta variant of the coronavirus has gained dominance in Italy, the National Health Institute said.
* Asian countries from Australia to Japan and the Philippines announced tighter COVID-19 restrictions, as they battle worsening outbreaks driven by the Delta variant.
* Japan said it will expand states of emergency to three prefectures near Olympic host Tokyo and the western prefecture of Osaka, as COVID-19 cases spike in the capital and around the country, overshadowing the Summer Games.
* Three-quarters of people infected with COVID-19 at July public events in a town on Cape Cod in Massachusetts were fully vaccinated, a study by the CDC showed.
* Canada must vaccinate as many people as possible and cautiously relax public health measures as case numbers creep higher at the start of what could be a fourth wave, the country's top health official said.
* Florida Governor Ron DeSantis issued an executive order on Friday blocking mask mandates in the state's schools, saying parents had the right to decide if their children would wear face coverings.
* Top U.S. infectious disease expert Dr. Anthony Fauci said he hopes regulators could as soon as next month start granting full approval for the use of COVID-19 vaccines.
MIDDLE EAST AND AFRICA
* Uganda partially eased a tight lockdown imposed 42 days ago to help stem a raging second wave.
* Botswana's health minister said the government was paying the equivalent of $15 a dose for the vaccine developed by China's Sinovac Biotech and almost $29 a dose for Moderna's shot.
* The protection that vaccines give against coronavirus infection, and potentially severe disease, is highly likely to wane over time so vaccine campaigns will continue for years to come, scientists told the British government's advisory group.
* Antibody tests do not reliably confirm that someone has had COVID-19, which means global estimates of infection rates are likely inaccurate, according to researchers.
* U.S. stocks dropped on Friday to pull further from record highs as an underwhelming earnings report from Amazon.com Inc AMZN.O dampened the market mood.
* U.S. consumer spending surged in June as vaccinations against COVID-19 boosted demand for travel-related services, but part of the increase reflected higher prices, with annual inflation accelerating further above the Federal Reserve's 2% target.
