Yemen, which reported its first confirmed Covid-19 case on April 10, had recorded only 2,064 infections with 600 deaths from the disease

A first-of-its-kind study using satellite images to count fresh graves and analyze burial activity in Yemen has estimated the death toll there from Covid-19 or Covid-related causes is far higher than official government figures suggest.

Using high-resolution satellite imagery, researchers at the London School of Hygiene & Tropical Medicine (LSHTM) analyzed burial activity at all identifiable cemeteries in Yemen’s Aden region and calculated an estimated 2,100 “excess deaths” during the Covid-19 outbreak between April and September.

“This total is best interpreted as the net sum of deaths due to Covid-19 infection and deaths indirectly attributable to the pandemic,” they said. The indirect deaths would be those caused by disruptions to health services or by measures which may have caused problems accessing food, they added.

Humanitarian and global health experts had expected the Covid-19 pandemic’s impact on Yemen to be severe, not least because the country’s five-year conflict has disrupted already weak health services and led to overcrowding, food insecurity and shrinking humanitarian aid.

But as of 25 October 2020, Yemen, which reported its first confirmed Covid-19 case on April 10, had recorded only 2,064 infections with 600 deaths from the disease.

No comment was immediately available from Yemen authorities on the satellite estimates but the internationally recognized government has said previously that it reports figures daily for areas under its control and nothing is hidden.

Francesco Checchi, who co-led the study, noted that having an accurate picture of Covid-19’s impact “is vital for effective government and humanitarian responses”.

“By estimating excess mortality, we aimed to develop a more accurate estimate of the toll of Covid-19 in Yemen,” he said.

The researchers, whose findings have yet to be peer-reviewed by other experts, also cited other material as supporting their estimates.

In May, videos posted on social media and information from informants reported high numbers of fresh graves, suggesting a spike in burial activity, they said, adding: “The use of mechanical excavators in place of human gravediggers suggested that demand exceeded routine capacity.”

During the same period, the global medical charity Médecins sans Frontières reported a peak in hospital admissions, with a very high case-fatality ratio, and media said a shortage of personal protective equipment had forced several hospitals to close or reject patients with Covid-19-like symptoms.

The research, funded by aid from the UK government, was led by LSHTM and the technology company Satellite Applications Catapult, which specializes in geospatial analysis.

The researchers said they are now conducting a similar study in Mogadishu, Somalia.

“Though our method cannot distinguish direct from indirect virus deaths, estimating excess mortality attributable to the Covid-19 pandemic in a humanitarian setting captures the whole system impact,” said Emilie Koum Besson, who co-led the work.
