Dr. Butler - Jones: Certainly, two things about that I guess, firstly as it's been said, we do see from time to time and this is something that people would not know that in fact
human viruses can be spread to pig.
We may never know, but certainly it's shown itself with it's ability to be
a human virus and that's really what we are dealing with at this point and more will come as we understand the virus better.
Dr. Evans: I would just add to that, thank you for the question again, I would just add to that, that David indicated at this point an time the issue of being
a human virus having been introduced to the pigs and the characterization of this virus shows that it is still that virus.
So in this specific instance we know it's
a human virus that can spread.
Question: What about, I guess the assumption was always that the virus may have started in pigs and then transmitted to humans and then humans started passing it on each other as
a humans virus.

human viruses emerge.
Other primate immunodeficiency viruses, such as SIV and HIV - 2, the rarer and less virulent
human virus, do not need their host's cyclophilin A to replicate.
In flu surveillance, researchers look primarily for the genes encoding the virus's surface proteins, hemagglutinin and neuraminidase; if they sequence the so - called internal genes as well, they might detect new genes slipping into
human virus strains in the run - up to a pandemic, they say.
Among
human viruses, HIV is uniquely variable.
Most individuals tested had a strong antibody response to the seasonal H3N2
human virus - derived H3 subtype, part of that year's vaccine (2009 - 2010), but many also had strong measurable antibody responses to group 1 HA (avian H5, H6, H8, H12) and group 2 HA (avian H4, human H7) subtypes.
Meanwhile, Memish says he had sent samples to the Wellcome Trust Sanger Institute in Hinxton, U.K., which sequenced the complete
human virus and managed to sequence some small fragments of the camel virus.
Drosten suspected that contamination had happened, and that what the researchers called the camel virus was actually
the human virus as well.
Members of the board demanded that the genetic recipe for ferret flu be redacted before publication, sparking public hysteria: Had the scientists created lethal, transmissible
human viruses?
But he cautions «we're at the starting line... we're not really at the point of understanding the virulence of
a human virus.»
The result — the first complete structure of a virus in the flavivirus family — reveals a layered, soccer - ball - like shape lacking the spiky projections characteristic of many
human viruses, the researchers report in the 8 March issue of Cell.
Although fears about chicken flu are receding, some scientists, including John Tam, professor of virology at the Chinese University in Hong Kong, warn that this strain could still wreak havoc by recombining with an existing
human virus.
Yet a 2011 study in Wisconsin found that
human viruses had managed to infiltrate deep aquifers, probably moving downward through layers believed to be a permanent seal.
The Institute of Virology was founded in 2007 and provides diagnostic service to UK - Bonn, covering
all human viruses and producing over 80,000 diagnostic records annually.
«HIV is
a human virus,» Devin Sok of the Department of Immunology and Microbiology at The Scripps Research Institute said in a press release, «but researchers can certainly learn from immune responses across the animal kingdom.»
Finally,
some human viruses and bacteria are resistant to chlorination at sewage treatment plants, and they are discharged with the treated effluent into nearby waterbodies.
EBV, also known as human herpesvirus 4, is one of the most common
human viruses, and it creates a global health problem.
The Viruses That Made
Us Human Viruses that infected our ancestors provided the genetic foundations for many of the traits that define us.
As a result, some of Harrison's current projects, related to
human virus structures, are moving away from X-ray crystallography toward electron cryomicroscopy (EM).
The long - time focus of the Simmons lab has been on emerging and reemerging
human viruses, from Ebolavirus and SARS - CoV through to the current Zika virus epidemic.
Not only had Dalldorf and Sickles identified the first members of a very large group of
human viruses, but they also introduced and popularized a new and inexpensive animal into the virology laboratory — the suckling mouse.
They recombine the genetic material, so when they produce new viruses it's got part of the human and part of the pig; you worry that if it gets enough of
the human virus, it will be able to bind to human receptors.
