How Can Sequence Data Be Used to Track Flu Virus Evolution D

How Can Sequence Data Be Used to Track Flu Virus Evolution During Pandemic Waves? In 2009, an influenza H1N1 virus caused a pandemic and the virus has continued to in outbreaks across the world researchers in were curious about why the virus kept appearing initiatives They hypothesized that newly variant strains of the H1N1 virus were able to evade human immune system defenses, to test this they needed to determine if each wave of the flu outbreak was caused by a different H1N1 variant strain.

Solution

Close relationship between A/Taiwan 1018/2011 and A/Taiwan/552/2011. Because this phylogenetic tree represents the relationshiip between various mutants of H1N1 virus. Each node shows two lineages and they are separted due to mutaions. More closely variants of A/Taiwan 1018/2011 and A/Taiwan/552/2011 represnts differences between the sequences of variants.
