Ett utbrott av ebola i Uganda har dödat minst två personer, skriver BBC. En tredje person misstänks också ha dött av sjukdomen.
I somras, i samband med ett annat utbrott, dog 17 människor.
Samtidigt kommer uppgifter om att viruset kan vara luftburet.

Under conditions of the current study, transmission of ZEBOV could have occurred either by inhalation (of aerosol or larger droplets), and/or droplet inoculation of eyes and mucosal surfaces and/or by fomites due to droplets generated during the cleaning of the room. Infection of all four macaques in an environment, preventing direct contact between the two species and between the macaques themselves, supports the concept of airborne transmission.

They did find aerosolized Ebola in air samples, and some of the macaques did come down with symptoms of Ebola. So, it looked like pigs could spread Ebola through the air, which is something that had already been suggested by the epidemiology of the 2008 pig Ebola outbreak. It’s always nice when experimental data matches up with that observed during a real-life occurrence of the virus.
*However*, the kicker was not that Ebola is transmitted by air in human outbreaks, but rather that there may be something unique about pig physiology that allows them to generate more infectious aerosols as a general rule–so though aerosols aren’t a transmission route between primates (including humans, as well as non-human primates used experimentally), pigs may be a bigger threat as far as aerosols. Thus, this may be important for transmission of swine influenza and other viruses as well as Ebola.
So unless you’re sitting next to an Ebola-infected pig, seriously, airborne transmission of Ebola viruses isn’t a big concern. (Perhaps this corollary should be added to this handy diagram examining your risk of Ebola).
Jag sade ju att det dokumenterats luftburen spridning mellan djur, inte mellan människor, än.
