UN agencies responded to a study that suggests the virus Respiratory Syndrome Middle Eastern or "another very similar" to have infected humans from populations of camels.

The World Health Organization (WHO) and the Food and Agriculture Organization (FAO) considered premature to conclude the type of animal that would have been responsible for the transmission.

According to the agencies, research done on camels dromedaries "provides some additional information," to have found antibodies to the virus. The study was conducted by the National Institute of Public Health and Environment of the Netherlands and published in The Lancet newsletter.

The spokesman for the WHO Genebras, Tarik Jasarevic, said there was no detection of the virus itself on camels.

He said the discovery of antibodies indicated that there was a previous infection with this virus or similar. "As I said, the animals were infected at some point, being necessary to find the own virus to conclude that it is the same as that detected in humans."

In a statement, the FAO points out that the samples were taken where there were no reports of human cases, and the camels tested were isolated from other animals of the same species for many years.

The WHO said Furthermore, the results indicate that the antibody or the virus a coronavirus found similar "occurs in some camel and potentially other species."

However, isolating the virus in different species and compare them genetically would be "the only way to know for sure whether the virus that affects humans is the same as that found in camels.

Next step

The WHO argues that the next critical step for investigations of animals would find the virus itself in them or in populations of camels, which had not yet happened.

The organization draws attention to the fact that the results do not provide any ideas alone, about how humans become infected.

Most human cases reported had acquired the infection through contact with other infected humans. Even where there were sporadic reports of direct contact with camels, full note of WHO.

Since it was identified last year were recorded 96 confirmed cases and 46 deaths due to the new coronavirus.
