Zika Americas: what if the French Polynesia had nothing to do?
PAPEETE, April 3, 2016 ...
What if Zika had arrived in Brazil, not in 2015, nor in 2014, but between May and December 2013? This is a new hypothesis brought by British researchers from the University of Oxford, and Brazilian Evandro Chagas Institute. According to them, football fans who came to Brazil for the World Cup in July 2014 are not responsible for the introduction of the virus in South America. They also exonerate Tahitian paddlers came to participate in the world championship of speed va'a in August 2014. These researchers hypothesize that Zika joined Brazil in 2013. From comparisons of genomes collected Zika among Brazilian patients with the genomes of viruses from French Polynesia patients and the Cook islands, it appears that the virus circulating in Brazil is extremely close to that which prevailed at home.
The authors first direct their views to the Cup June 2013 football confederations, in which the Tahitian team -the Toa Aito (with 23 players selected) - came to face the cream of world football in Brazilian temples football. The problem with this theory: is that Zika epidemic is declared in French Polynesiaonly later, as of October 2013! No one can accuse the Toa Aito of being the first Zika virus carriers in Brazil, although, ironically, their 3rd and last match was played at the stadium in Recife, Brazil epicenter of the current outbreak.
However, these researchers noted that from the end of 2012, air links between Brazil and the countries of Southeast Asia where Zika circulating endemically, increased 50% from 3,500 monthly passengers to 5,000 people per month. Trade with Thailand, the Philippines, Indonesia increased significantly. It is therefore possible that travelers from these Asian countries where Zika had been circulating for many years without causing disease outbreak, have carried the virus in Brazil.
...
To know with more details of the road of Zika to Brazil, researchers would need more genomes of viruses from the South-East Asian countries to compare, but some countries have not kept the samples. However, this study gives a serious lead on how Zika could have suddenly land in French Polynesia: what if the Toa Aito had been infected with the virus during their visit to Brazil in June 2013 during the global competition? Tahitian delegation could have imported the virus to Tahiti without knowing where the epidemic of Zika was confirmed at the end of October 2013.
