Orthobunyaviruses are a group of viruses that includes the Oropouche virus, which is different from flaviviruses like dengue and alphaviruses like chikungunya.  

No, despite the name, Sloth fever is not contracted via contact with sloths.  

Sloth fever is not directly contagious between humans. It is transmitted through the bites of infected mosquitoes and biting midges.  

The CDC issued a warning due to the spread of the Oropouche virus in regions near the US and to advise caution for residents, especially those traveling to affected areas.
