 The World Health Organization's chief security says the Delta variant of COVID-19 forced identified in India is becoming the globally dominant variant of the disease. Sumiya Sramin-Eten also voiced disappointment in the failure of pure vaccine candidate in a trial to meet the WHO's efficacy standard, in particular as highly transmissible variant boasts the need for new effective shots. Britain has reported a steep rise in infections with the Delta variant, while Germany's top public health official predicted it would rapidly become the dominant variant there, despite rising vaccination rates. The whole situation is so dynamic because of the variants that are now circulating and as you said the Delta variant is well on its way to becoming the dominant variant globally because of its significantly increased transmissibility. We need more data again from well designed studies on the efficacy of the different vaccines that are in use in different countries against the different variants. When you look and any of you can look on a website and see the numbers, when you see the absolute numbers it doesn't appear that our African region is in necessarily bad shape it's only in the last week represents just over 5% of global cases and over 2.2% of double deaths but given what Maria said about under diagnosis on the continent it's trajectory that's very very concerning and in the last week we've seen over 100% increases in Namibia and Sierra Leone and Liberia in Rwanda and Zambia and Zimbabwe and Malawi and Lusoto in Congo and South Sudan. We've seen between 50 and 100% increase in cases in places like Mozambique in Cote d'Ivoire. Every region has countries that are now facing a steep increase in cases and deaths. Many countries in Latin America have rapidly increasing epidemics and others have plateaued at high level. In Africa cases have increased by 52% just in the past week and deaths have increased by 32%. We expect things to only get worse.
