The first confirmed COVID-19 case was reported on March 14, 2020 and the government was proactive in implementing substantial preventive measures at an early stage. As of mid-June and early August 2020, preventive measures had been loosened to a large extent, lifting the stay-at-home order and closing of the airspace and allowing businesses to reopen. However, since mid-December, due to onset of a second wave, the authorities gradually reintroduced preventive measures. These measures include limiting the number of international flights to one per airline; requiring foreign visitors to present a negative PCR test and to quarantine for 5 days upon arrival in Equatorial Guinea; requiring local travelers between the continental and insular regions to present a negative PCR test or vaccination card; and restricting social gatherings, including through closure of all pubs/nightclubs and a curfew. Since February 15, 2021, in-person classes at all public and private schools in the main cities of Bata and Malabo had been suspended. In Malabo, classes resumed on May 20 and the curfew was relaxed to start at 10pm, given more benign recent Covid trends there. Since April, the government has scaled up its vaccination campaign, which now includes vaccination posts in all districts of the country. As of early June, some 148,000 people (approx. 10 percent of the country's population) have received at least one vaccine dose. After accidental explosions on March 7 in the country's largest city of Bata, which caused humanitarian tragedy and widespread destruction, a Covid lab there could again be operationalized. This has allowed for resumption of a massive testing campaigns also in Bata (in addition to the capital of Malabo).
