SSCE VCE Biology Immunity and Disease Response: Zika fever is a rapidly emerging

Question

Zika fever is a rapidly emerging viral disease. It is most commonly transferred from one person to another by the Aedes species of mosquito.

Zika fever in people was discovered in Uganda in 1947. It was thought that a bite from a mosquito had transferred the virus from monkeys to humans.

The symptoms of Zika fever are usually mild and 80% of infected humans do not show symptoms. Infection of pregnant women, however, can cause severe defects in their babies.

One way that diseases, such as Zika fever, are thought to occur is when a pathogen infects humans from an animal host.

Identify one social or economic factor that could lead to this transfer between hosts.

When scientists attempt to identify a particular disease, they can look for specific antibodies in infected humans. Scientists trying to identify Zika fever infections found that testing for the antibodies produced against the Zika virus often gave them incorrect results. This was because the antibody tests that had been developed could not always identify the difference between the antibodies produced against the Zika virus and the antibodies produced against other viruses.

Explain why making a correct identification of a viral pathogen is important in the control of a disease.
