Human to human spread: not to worry
The recent news on a son-to-father bird flu infection should not cause alarm. Studies done on the samples taken from father and son shows that the virus has not yet mutated into a highly contagious strain. The people with whom the father and son came into contact with were also not infected, an indication that the virus must have been passed on due to very intimate contact. This is good news as people are fearing a pandemic. But despite this development, authorities and researchers are still on the watch for further spread, and are continuously searching for a vaccine to fight the deadly disease.
