Based on the text, which of the following statements accurately describes how environmental or human-induced changes contribute to the emergence and spread of viruses?

  • A: Building new roads in remote areas always reduces viral spread by increasing isolation.
  • B: Deforestation for cropland expansion limits human-animal contact, thereby preventing zoonotic spillover.
  • C: Global climate change can expand the geographical ranges of mosquito species, leading to new areas experiencing mosquito-borne diseases like Dengue fever.
  • D: Public health strategies primarily focus on developing vaccines and rarely consider methods like mosquito netting.

Explanation

The text directly states: 'The possibility that global climate change has allowed mosquito species carrying these viruses to expand their ranges and interact more is troubling because of the increased chance of a mutation allowing a virus to jump to a new host.' It also mentions Dengue fever appearing in new regions.
