In early April, , director of the Latin America Program at the 嘿嘿视频 School of Veterinary Medicine, addressed the current state of avian flu at a webinar hosted by the 嘿嘿视频 Grand Challenges鈥

鈥淚t is causing a totally unprecedented scale of global spread and mortality,鈥 said Uhart on the newest strain. 鈥淲e have never seen anything like this before. It鈥檚 killing hundreds of thousands of birds, and tens of thousands of mammals.鈥 

Uhart is especially worried about new strains and virus movement into new species. Currently, the largest scales of mortality have been documented in seabirds, waterfowl, and mammals like elephant seals. A few human cases have also been documented, along with cases in domestic pets and livestock. 

Uhart has documented cases in the wild from the beaches of Argentina to Antarctica, and continues to track the impacts on affected ecosystems. 

鈥淔or those of us who have been on the beaches these last couple of years, you experience the silence鈥搕hese animals are just not there."

鈥淔or those of us who have been on the beaches these last couple of years, you experience the silence鈥撯搕hese animals are just not there,鈥 Uhart said. 鈥 Maybe over time they鈥檒l come back, but we just don鈥檛 know what the consequences are. In the conservation world, we鈥檙e bringing this message that we need to be more alert and monitor what the impacts are in the near future.鈥
