and president delivering that have to plant one of the skaters. in the favelas the drinking water was infested with mosquito larvae. the authorities added a new insecticide to every water container although no one knew if it would stop the epidemic. so scientists focused on the root of the problem the virus itself. being. tongue emigrated from china to the united states to study viruses i was always interested in viral and seeing viruses are so clever so efficient it s fascinating. when the zeek epidemic broke out in brazil his team were busy studying other
decision to mass produce a vaccine depended on the scale of the epidemic. by the middle of twenty seventeen zico have managed to cross the atlantic to keep verd near the densely populated coast of africa the continent where the virus had first been found. will it produce an epidemic in africa. that s a question being investigated by dr sater salinas she believes the answer lies in the past several decades ago after zico was identified in uganda. but why were there never any cases of microcephaly here. in the u.k. strong trace on fixing someone s theory is that the brazilians e.q. virus developed from the original african strain and became more aggressive on
a stick it into neutral toxic. air salinas knows that the zeek a virus that caused the epidemic in brazil is subtly different from the african one . could that difference explain the villains of the brazilian virus. in there we decided to start by looking at the egress iwm a severe regional african strain and the virus responsible for the epidemic in brazil in the new policy. in early twenty seventeen dr salinas his team already had access to the brazilian virus but to trace its evolution they also needed the african virus that was identified several decades ago when nobody much cared about or studied. the search for the african strain took months. but then the breakthrough.
to receive my email from him knowing it and asking him for he s the best expert working on your development a talking me immediately and first rounds was do you have an abortion your decision was made on the spot over the phone to call him. within days the two team started working together. so we opened the box and we took out the flask and it s just as floss with these little brain cells they were so large they. you could actually see the brains and the tear of. the experiment was conducted with painstaking care because the result was a vital importance half of the many brains were infected with the virus the other half were used as controls and left to develop normally with the virus affect development. and this was definitely
a little bit of a nerve racking point because we have to incubate them with the sick a virus and then wait for them to develop and that takes a little bit of time. to finally have been getting seen ok and what did seek a virus do to these and was pretty dramatic. the result was clear. had had a significant impact. it s amazing it s amazing results the ones that hezzy converse on that were so much smaller only after one week they send a picture taken from a cell phone like wow doubt this is really telling us something and then see how worst teams link to michael supple so between embrace it just watch much more smaller if you compared to normal ones. but the
