For which of the following viruses do we use serological testing for diagnosisGroup of answer choicesZika virusCMVHIVDengue virusAll of the above

To determine which viruses among the options provided utilize serological testing for diagnosis, let's analyze each option.

1. Zika Virus: Serological tests are commonly used to detect antibodies against the Zika virus, so this virus typically involves serological testing.

2. CMV (Cytomegalovirus): Serological testing is a key diagnostic tool for CMV as it can identify specific antibodies (IgM and IgG) that indicate current or past infection.

3. HIV (Human Immunodeficiency Virus): Serological tests are the standard for diagnosing HIV infection. Tests detect antibodies to the virus as well as the virus itself in some cases.

4. Dengue Virus: Like the others, serological testing is employed to detect dengue virus infections by identifying specific antibodies developed in response to the virus.

Given that all of these viruses can be diagnosed through serological testing, the correct choice is:
