Answer #1

Ans:

The answer is 'the virus is using mosquitoes as vectors'

Explanation:

Certain diseases caused by pathogens that are transmitted by vectors are called as vector-borne diseases.Vectors are the living organisms that carry the infectious viruses,bacteria or even parasites from one human to another or from animals to human.These vectors are often blood feeding insects which while feeding on an infected host,accidently ingest the pathogen.These pathogens once inside their vector,starts replicating,making their vector infectious and capable of transmitting the disease, every time they feed on their hosts by directly injecting the pathogen.Mosquitoes are classical example of vectors that carry pathogens causing diseases like chikungunya(virus pathogen),Malaria(Parasite Pathogen),Zika(Virus pathogen) etc.

An epidemiologist is investigating two suspected risk factors for a deadly disease (“wasting disease”). One of the potential risk factors is infection by virus A, while the other potential risk factor is having a mutation in a gene on chromosome 10. 6,500 participants were selected for the 2 year study. Of those participants, 500 were infected by virus A but did not have the genetic mutation, 750 had the mutation but did not have the virus, and 400 had both...

A highly virulent strain of a common and previously innocuous virus has been discovered and you have decided to conduct a series of experiments to understand what has caused this new strain of virus to be so virulent. Fortunately, the innocuous strain was known to have a small, linear double-stranded DNA genome with only a few genes. We find that the virulent strain has two new genes. Innocuousstrain: Gene A Gene B GeneC Virulent strain: Gene A Gene B gene...

Which process most likely accounts for the Salmonella newly acquired ability to make a toxin?

Tuberculosis (TB) is a disease caused by bacteria that are spread through the air from person to person. If not treated properly, TB disease can be fatal. People infected with TB bacteria who are not sick may still need treatment to prevent TB disease from developing in the future. It is estimated that about 3% of the population in a given country is infected with TB bacteria. There is a skin test for TB infection. However, the test is not...

In the Herd Immunity assignment, you saw visualizations of diseases like Seasonal Flu, Ebola, and Measles spreading through populations at various levels of vaccination. In the event of a new, or "novel" disease there is no vaccine available. This is comparable to the infection rates you saw at 0% vaccination. T he pandemic we are currently living through is caused by a novel coronavirus called COVID-19. Explain how, in the absence of a vaccine, social distancing can help to slow...

Suppose that you are interested in investigating the association between retirement status and heart disease. One concern might be the age of the subjects: An older person is more likely to be retired, and also more likely to have heart disease. In one study, 127 victims of cardiac arrest were matched on a number of characteristics (that included age) with 127 healthy control subjects. Retirement status was then ascertained for each subject. a) Test the null hypothesis that there is...

Until recently, the Zika virus was a rare and mild public health concern and little was known about it. In early 2015, Brazil reported an epidemic of Zika viral infection. Reports soon followed of unusual numbers of neurological disorders such as microcephaly in newborns, a condition characterized by a very small head and poor brain growth. (a) Explain why we cannot conclude from this information alone that Zika infections cause microcephaly in newborns. Select the correct choice from the options....
