An official said almost four million cases worldwide were reported last week to WHO......................................
July 31, 2021The World Health Organisation says COVID-19 deaths have increased by 80 per cent in the past one month in Africa, mostly driven by the highly-transmissible Delta variant.
The director-general blamed the rise of cases on increased social mixing and mobility, the inconsistent use of public health and social measures, and inequitable vaccine use. In June, the WHO chief announced the setting up of a technology transfer hub for mRNA vaccines in South Africa as part of WHO’s efforts to scale up production of vaccines and their distribution in Africa.
According to him, WHO’s goal remains to aid every country in vaccinating at least 10 per cent of its population by the end of September.“We are a long way off achieving those targets. So far, just over half of countries have fully vaccinated 10 per cent of their population, less than a quarter of countries have vaccinated 40 per cent, and only three countries have vaccinated 70 per cent.”
Lead WHO epidemiologist and COVID-19 technical lead, Maria Van Kerkhove, explained that the Delta variant had certain mutations that allow the virus to adhere to human cells more easily and that experts were also seeing a higher viral load in individuals infected.She called Delta “dangerous and the most transmissible SARS-CoV-2 virus to date,” adding “there are some laboratory studies that suggest that there’s increase replication in some of the modelled human airway systems”.
“It’s in the virus’s interests to evolve, viruses are not alive they don’t have a brain to think through this, but they become more fit the more they circulate, so the virus will likely become even more transmissible because this is what viruses do, they evolve they change overtime.
