Laboratory diagnosis of arbovirus infection is usually accomplished by Serum or cerebrospinal fluid (CSF) testing Detection of virus-specific IgM and neutralizing antibodies. In some cases, molecular detection may also be used.

Are arboviruses genetically related?

Global climate change, rapid urbanization, rapidly expanding international travel, expansion of mosquito populations, vector capacity, and host and viral genetics may conspire to contribute to the re-emergence of arboviruses.

Do viruses cause tissue damage?

Some viruses do have high levels of intrinsic pathogenicity, and often have significant mediating effects fatal, tissue damage in a high percentage of infected people.

How fast does the virus reproduce?

Different viruses have different timescales; it may range From 8 hours (eg, poliovirus) to over 72 hours (eg, cytomegalovirus). Infection of susceptible cells does not automatically ensure viral reproduction and the emergence of viral progeny.

How do viruses replicate in the human body?

Virus can’t copy It reproduces on its own, but on the host cell’s protein synthesis pathway. This is usually done by the virus inserting its genetic material into the host cell, selecting proteins to produce viral replication, until the cell bursts out with a flood of new virus particles.

Who found the real cause of yellow fever?
