Formation of new flu strain. Computer illustration showing two influenza (flu) viruses (blue and green) infecting a pig cell (pink sphere). The viruses use the host cell's machinery to reproduce copies of themselves. During this process the two genomes may be mixed and repackaged to form a new strain (red). If the new strain is able to infect humans this introduces a new strain into the population that there is no immunity to, giving it the potential to cause a pandemic. | |
