"Test, test, test" has been the mantra for defeating the novel coronavirus, but African countries are finding themselves at the end of a long global queue for the chemical reagents and other commodities necessary for administering diagnostic tests, according to public health experts.
Although mass testing is seen as a key component to slowing transmission, African health authorities are struggling to compete with richer, more powerful countries when it comes to procuring the scarce testing material on the global market, notes a new commentary published in The Lancet scientific journal.
Building self-sufficiency
Many African researchers foresaw this scarcity and the consequent need for African countries to be as self-sufficient as possible when it comes to diagnostic tests.
Given the global shortages - particularly the reagents necessary to run polymerase chain reaction (PCR) tests, which remain almost exclusively the basis for diagnosis - African countries need to take two paths forward, suggests Dr. Misaki Wayengera of Uganda's Makerere University.
But there are only a few diagnostics manufacturing facilities across Africa that have developed RDTs and could work on COVID-19 solutions, acknowledged Dr. Moses Alobo of the African Academy of Sciences, who is leading the effort to coordinate elite researchers across the continent.
