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

According to published reports, this is an isolated case of swine flu detected in an 83-year-old man who has not shown any symptoms and who, according to the information available, has not had direct contact with pigs. This raises the possibility of human-to-human transmission, which can occur in exceptional cases with swine flu viruses, although it is not common or frequent.

It is important to emphasise that the fact that the patient is elderly and has had no symptoms is reassuring from a clinical point of view. At present, there are no signs of sustained transmission or an increase in cases, and such findings are usually detected precisely because of robust epidemiological surveillance systems and routine sequencing of respiratory viruses. The identification of such a case indicates that the system is working, not that we are facing a situation of public alarm.

In this context, it is appropriate to continue monitoring and epidemiological investigation to confirm the route of transmission and rule out new cases, but based on the information currently available, the risk to the general population can be considered low.
