By April 15/2020 the zoonotic source of SARS- CoV- 2 had not been confirmed, however, the sequence-based analysis suggested bats as the main reservoir. 7 A publication on April 09, 2020, the theory behind our healthcare model has been refuted with the COVID-19 pandemic which also implies lasting changes in that new medical model. 10 The theory about the genesis of COVID-19 and bat to man transmission had not been substantiated.

An article published online April 20/2020 “… Optimal mitigation policies might reduce peak healthcare demand by 2/3 and deaths by half. And resulted in hundreds of thousands of deaths …. Drastic revision of R₀ was called for. 11 The virulence or death/cases had been underestimated. Definition of R₀ had undermined non-contact e.g. direct projection, or indirect transmission.

But, instead of focusing on which model is correct, we should accept that “one model cannot answer it all” and that we need more models that answer complementary sub questions that can piece together the jigsaw and halt COVID- 19 spread. 11 There can be methodology that can be applied to any form of model, e.g. the expansion method in diffusion studies- model that does not presuppose invariance of model parameters

As of April 17, 2020, across the 10 countries with most COVID-19 deaths the total number of infected to be approximately 4, 95%CI 210 times the number of confirmed cases. 12 in short the ratio covert/overt cases or concealed/revealed, or 1/pathogenicity had been were underestimated.

April 2020 recommendations said that future studies addressing the diagnostic performance of tests for COVID-19 in the Brazilian population were urgently needed. 14. A letter to the editor published online March 9/2020 stated ‘currently, RT-PCR is a reliable test’ in detecting both symptomatic and asymptomatic COVID-19. 5 As to asymptomatic detection only occurs if patients are followed up proactively from the time of exposure. 15

Screening and testing depend on, among others, timing, type of test, site from where specimen was taken, symptoms. Also the time spent in the development of diagnostic/screening test for COVID-19 might have contributed to the early spread.

Body temperature screening may miss travelers incubating the disease or travelers concealing fever during travel. 5 Incubatory carriers might have been missed. Screening based on body temperature, and the time spent development of non-contact measurement of body temperature might have added to the problem of early detection.

It will not be morally acceptable to stop flying to China today because they’ve a temporary problem. 21 Even though the Ethiopian Airline planes evolved into cargos, early in the pandemic COVID-appeared a temporary problem.

Different sources gave different information on the onset of COVID-in Ethiopia, for instance Ethiopia confirmed its 1^st case of COVID-19 on Friday 13^th February 2020. 18 The 1^st COVID-19 case in Ethiopia was detected and reported on March 13, 2020. 19 Ethiopia, with about 107 million people, confirmed its 1^st case of COVID-19 on March 13. 20

Nevertheless, between COVID-2019 emergence in December 2019 in Wuhan, 2 and the time of the WHO’s declaration COVID-2019 a Public Health Emergency of International Concern on Thursday, 30 January 2020, 5 the Ethiopian Airlines might already have had several flights to China. The Ethiopian government was said to have displayed remarkable reluctance to curtail its Ethiopian Airlines flights and an executive said “It will not be morally acceptable to stop flying to China today because they’ve a temporary problem.”  17 Furthermore on June 19 2020 the Ethiopian official on Friday called for boosting China-Africa solidarity in fighting against the COVID-19 pandemic. 22 These issues together with others put Ethiopia- and other countries at great risk.

Although on June 18, Ethiopia appreciated China for “successfully curbing the spread of the COVID-19 disease and for its unyielding support to Ethiopia's fight against the scourge." 22 This shows people have no good advisees. The flights were scourge. In earlier time of the pandemic, concerned with the continued flight, the BBC Africa focus had interviewed the same foreign minister he said the health system can cope it.Rather the impact of HIV and war in Ethiopia before 2000 might have had affected the would be now old age which is COVID-19’s stronghold, making COVID-19’s impact upon Ethiopia lower as revealed by the number of deaths, which is the most fraught outcome, lower.

On 19 June, the Government eased quarantine regulations by announcing that “all travelers arriving at Bole International Airport in Addis Ababa carrying a certificate of negative PCR SARS-CoV-2 test, done up to 72 hours before arrival, will be able to follow the 14-day quarantine at home after giving sample upon arrival. 23 Certificate is no guarantee about the future.

Travelers and returnees with no certificate of negative PCR SARS-CoV-2 test results will be quarantined for 7 days in the designated sites, tested, and then able to self-isolate for additional 7 days at home.” 23 This statement is elusive. In the month of June 2020, the radio broadcast of one region announced in Amharic that all returnees (likely this is related to movements via borders), who arrived to that region during the previous 2 months had to report in personally to the regional office.

Government’s movement restrictions related to COVID-19 have been eased allowing inter-regional movements throughout the country. 23 There were deep rooted problems with ethnic federalism.

Although it was reported that Ethiopia had about 107 million people, 20 and, an article in April said that, as many countries lack population based sero- prevalence studies, straightforward demographic adjustment can be used to deliver useful estimates of the total number of infected cases, 12 Demographic adjustment and may not be applicable for Ethiopia due to reluctance on census which had to be conducted every 10 year was conducted only in 2007. This adds to the problem of error projection. Also it has to be noted that COVID-19 was not responsible for all deaths during the previous 9 months of 2020.
