Reacción a "A case of swine flu has been detected in Lleida, which may be due to human-to-human transmission"

I'm not surprised. Often, when flu is circulating, if there are no symptoms, it is not analysed in detail unless there are complications or someone goes to hospital and is tested. The fact that the patient has not had contact with animals means that they have been infected through contact with another person, who in turn may have had contact with animals or with another person in contact with animals. The thing is, flu viruses can be dangerous, they can recombine, as happened with the first pandemic of the 21st century. In addition, there may be a serious health problem in people who have a weak immune system for various reasons, both congenital and due to illness. The fact that it has been detected makes us appreciate the importance of detecting viruses that are circulating in the UK, because with this information we can be better prepared for possible complications later on.
