The discovery is the closest anyone has come to finding the original virus in the wild.Īll along the railway’s path, a Reuters analysis has found conditions ever-more ripe for a “zoonotic spillover”, as a leap by a new virus from animals into humans is known.īat viruses have been the source of multiple health crises besides those related to coronaviruses, including recent outbreaks of Ebola, Nipah and Marburg. Three of those pathogens, all found among horseshoe bats here in Feuang district, north-west of the Laotian capital, are closely related to early strains of Sars-CoV-2, though not yet capable of sparking a deadly pandemic.
They know, however, it is in the coronavirus family, which is found in some horseshoe bats and other types common in tropical Asia, including Laos.īetween 20, researchers from France’s Institut Pasteur detected more than two dozen different coronaviruses in a sampling of 645 bats in northern Laos. Scientists have yet to find the source of Sars-CoV-2. That includes people or goods that may have had contact with live animals in a wildlife trade that has been linked to past outbreaks. The train also enables the fast movement of people and goods from rural to populous areas, where viruses can easily multiply and spread. Some scientists say the rail line is worrisome because development along its once-remote trajectory is accelerating tree loss and bringing humans into closer contact with bats.

“The Laos-China railway corridor has greatly benefited Laos in numerous ways, particularly the government’s effort to develop its economy and upgrade the living standard of the people,” wrote an unidentified official from the Laotian embassy in Washington in an e-mail to Reuters. Since the train began operating in December 2021, it has carried more than 14 million passengers and over 18 million tonnes of goods, according to the Chinese government. For Laos, a one-party communist state with close ties to its giant neighbour, the railway is meant to spur development, boost tourism, and forge even greater links with China.
