Fauci and David M. Morens, The New England Journal of Medicine, 13 Jan. 2016 Meanwhile, a virus linked to the mosquitoes known as Zika has spread throughout Brazil, causing thousands of cases of brain damage in babies born with abnormally small heads.— Joshua Emerson Smith, The Los Angeles Times, 4 Jan. 2016
