Purported advisories urging residents to stay indoors while national air force helicopters spray disinfectant over homes to kill off the novel coronavirus, COVID-19, have been circulated online in Sri Lanka and the Philippines. The warning messages have been shared thousands of times on Facebook and WhatsApp. But the claim is false; both the Sri Lankan and Philippine governments said their air forces were not involved in any such operations.
