Predicting The Virus Species Transmission For Future Outbreak

As some viruses can transfer one host to the other host and then adapting the new host. this type of transmission is knowing as the cross species transmission; and which is more oftenly seeing. But looking at the past may help the future when combating some viruses in humans; especially the evolutionary history of hantaviruses.

The study focusing on the evolution of the family Hantaviriade; of which orthohanta viruses are a member. By using phylogenetics, the study of evolutionary relationships among biological entities, such as species or genes, to investigate evolutionary history. His research has taken him to Alaska, Panama, Mongolia, and Japan and around New Mexico to gather samples from wild mammals and screen them.

Virus species transmission

But due to recent advances in our knowledge of relationships among hantaviruses, it became necessary to rename certain groups, for example, hantaviruses hosted by bats are now called mobatviruses or loanviruses. Soricid refering to shrews a small mammal that feeds on insects. All the hantaviruses that make people sick have just been reclassified as orthohantaviruses.

Buy the use genetics to reconstruct the evolutionary history of a virus; and the mammals that host that virus. By examines the historical pattern of movement of the virus from one species to another and how it has changed, or evolved, as it moved. That knowledge of the past can help predict how it will act in the future, and as mammalian hosts change with climate change, can potentially predict where “hotspots” of disease emergence may occur.

Relationships between individuals

The evolutionary history of viruses is difficult to investigate. A lot of the avenues for inferring evolutionary histories of organisms, such as fossils, are unavailable for viruses. Phylogeography uses genetic sequences to infer relationships between individuals, in this case, viruses and host species  separately, and then maps that diversity across multiple spatial scales. This is one example of temporary climatic events resulting in an increase in disease prevalence.

The wet cycle results in a population boom of the deer mouse; which increases the likelihood of an infected mouse getting into a residence; and infecting a human with HPS (hantavirus pulmonary syndrome). This is because climate changehas fundamentally altered local environments making it more conducive for the certain species of mosquito; that serves as the vector of malaria to survive. Climate change is shifting species ranges across the globe, expanding the current range of where disease can occur.
