U.S. government scientists have evince in the laboratory , for the first time , that pig can become badly disturbed from a particular metal money of the Ebola computer virus , yell Reston ebolavirus ( RESTV ) . The virus is known for being the only species of Ebola not to sicken mass so far . But the find suggest that it can still set a grave threat to farm animal , and the chances of it someday harming humans are n’t zero , either .
Reston was popularize in the 1994nonfiction bookThe Hot Zone , written by Richard Preston . In it , Preston go over the events of the first known Reston ebolavirus eruption in 1989 , when monkeys being used for animal research at a lab in Reston , Virginia begin dying en masse shot . Several animal handler and lab worker finally tested positive for antibodies to the virus , but to everyone ’s relief , none develop symptoms of the often calamitous hemorrhagic feverishness that accompanies other Ebola viruses . At the meter , Reston was considered a line of another Ebola virus , but it ’s now categorized as its own species of Ebola , one of six .
Over the year , inquiry andother outbreakshave once and for all show that Reston can sicken nonhuman primates . In 2008 , evidenceemergedthat it might have been the perpetrator behind eruption of respiratory illness at several pig farm in the Philippines . At least six farm proletarian were think to have been infect by the pigs , but , as before , these infections did n’t head to any human sickness . Still , the incident was alarming to epidemiologist .

Since 2008 , there ’s been onlylimited researchlooking at the connexion between the Reston virus and pigs . This raw study , publishedon Monday in the Proceedings of the National Academy of Sciences , was the work of scientists at the National Institute of Health .
Their solution suggest that the Reston ebolavirus can indeed infect and seriously harm pigs . They gave the computer virus to youthful domestic piglets between the age of three and seven weeks old , exposing them through the mouth and olfactory organ . The pigs develop severe respiratory disease , with most take to be euthanized within a hebdomad ’s time . What ’s more , the pigs pronto shed the virus in their respiratory nerve tract , point that they could transmit the virus to others during that time .
“ We conclude that RESTV should be deal a farm animal pathogen with zoonotic transmission impacting on creature and perhaps even human wellness , ” the authors wrote .

To be clear , the peril to people is entirely theoretic for now , but it ’s not impossible . virus like influenza already regularlycross overfrom animals like birds to pigs and then to people . Sometimes , this journeying can result in a powerful new flu strain that ’s easily transmissible and disease - causing in humankind . Other viruses — include the coronavirus that make covid-19 — often arise in creature before mutating into a reading that can become a incubus for the great unwashed . If pigs were to become a common reservoir of the Reston virus , it ’s possible that strains could one day emerge and be transmitted to humans that become just unlike enough to make us grim .
There ’s no need to panic right now . But if the covid-19 pandemic should instruct us anything , it ’s that we have to identify these viral menace long before they shed over into people if we require a fortune at stopping them .
“ The emergence of RESTV in pigs is a wake - up call as transmission into humanity through direct contact with pigs or the food strand is a possibility , ” the authors wrote .
