A US farmworker who caught bird flu after working with dairy cattle in Texas appears to be the first known case of mammal-to-human transmission of the virus, a new study shows. <\/p>\n

The dairy worker sought care in late March after developing painful red, swollen, weeping eyes with burst blood vessels.\u00a0He had no fever, however, and his lungs were clear, according to a letter about the case that was published in the\u00a0New England Journal of Medicine\u00a0on Friday. <\/p>\n

He reported no contact with sick or dead birds or other animals, but he did have repeated direct close contact with dairy cows in the same part of the state with other infected herds. <\/p>\n

Even though the man didn\u2019t become seriously ill, his case is important because it confirms that humans can be infected with H5N1 after contact with cows.\u00a0At the same time, it also leaves critical questions unanswered about a virus that the study authors said has \u201cpandemic potential,\u201d and it illustrates how hard it will be to track the infection in this vulnerable population of workers, where testing positive for an infectious disease might mean losing days of work and pay. <\/p>\n

\u201cFor farmworkers specifically, certainly these are folks that are that are living in a state of economic desperation, and what they\u2019re not going to do is, they\u2019re not going to test for something if they don\u2019t have paid sick leave, because they cannot afford to be sent home and told to stay home and not work,\u201d said Elizabeth Strater, director of strategic campaigns for United Farm Workers. <\/p>\n

Strater says UFW, like other groups, has heard rumors that there are dairy workers who are sick but don\u2019t want to be tested, but she said it\u2019s nothing that they\u2019re able to confirm. <\/p>\n

Health officials in Texas said they did test other sick dairy workers, including some with red eyes, but they turned out to have other illnesses, not bird flu. <\/p>\n

\u201cThe people tested volunteered to be tested,\u201d said Lara Anton, senior press officer with the Texas Department of State Health Services. <\/p>\n

\u201cIt\u2019s likely there were other people with symptoms who did not want to be tested so we cannot say with absolute certainty that no one else contracted H5N1. We can say for sure some of the people on dairy farms tested positive for other respiratory viruses that are commonly circulating in the human population,\u201d Anton said. <\/p>\n

In the case of the man who did test positive for bird flu, he took antiviral medications and recovered without any lasting problems, and his close family members received the drugs as a precaution, the letter says. <\/p>\n

Swabs of the patient\u2019s eyes and lungs revealed something interesting, too: His eyes were teeming with the H5N1 virus, but there was hardly any virus in his lungs.\u00a0That could mean the worker was infected through his eyes \u2013 either by rubbing them with contaminated hands or through splashes of contaminated milk \u2013 rather than through his lungs, and the virus never migrated there, or that the virus couldn\u2019t get a foothold in his lungs because it was adapted primarily to infect birds, not cells in the human airway. <\/p>\n

The letter on the case was written by researchers at the US Centers for Disease Control and Prevention along with doctors at the Texas Department of State Health Services and researchers at the Texas Tech Bioterrorism Response Laboratory. <\/p>\n

Health officials said they couldn\u2019t do further investigation of how the man was infected because \u201cepidemiological investigations were not able to be conducted at the farm\u201d where he worked.\u00a0 They were also unable to test other workers at the same farm. <\/p>\n
