What We're Watching: South Africa's COVID surge, the elusiveness of herd immunity, Malaysia's political emergency
South Africa shuts its borders: As a new COVID variant rips through South Africa, the country's prime minister Cyril Ramaphosa moved to close the country's land borders until at least February 15. This drastic decision comes after the government already shuttered public beaches and parks in recent weeks to avoid gatherings during the busy summer break. The newly discovered COVID variant is spreading at a much faster rate than the initial wave of infection, which peaked in the country in July. Medical professionals say that South Africa is experiencing a massive post-holiday spike in COVID-19 cases as people travelled (against government advice) to coastal areas, leading to massive spikes in hubs like Johannesburg and Pretoria. Hospitalizations and deaths are now surging in South Africa, and the 7-day rolling average of daily deaths has risen 75 percent over the past 14 days. While the country of 60 million people now accounts for a disproportionate 30 percent of all infections in Africa, it will not get access to any vaccines through the COVAX scheme until the second quarter of this year — if not later. Meanwhile, the virus waits for no one.
