COVID-19 (Novel Coronavirus)

COVID-19, a highly infectitious respiratory disease in humans, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus probably emerged from an animal source in Wuhan (China) and spreaded globaly from person to person. Most people infected with COVID-19 have had mild to severe respiratory illness with symptoms of cough, fever, and shortness of breath. In some cases, patients had pneumonia in both lungs, multi-organ failure, and even death. The World Health Organization (WHO), on March 11, 2020, declared the novel COVID-19 outbreak a global pandemic. [NALT]

Tospovirus

The Tospovirus (family Bunyaviridae) genus of viruses causes diseases of significant economic impact in many crops worldwide. Tospoviruses have the ability to swap whole segments of their genome with other members of the genus, creating new virus isolates with different vectors and modified host ranges, both of which can result in new diseases. Presently, there are eight recognized species belonging to this genus, of which five have been previously reported in the United States (i.e., TCSV, TSWV, GRSV, INSV, and Iris yellow spot virus [IYSV]). Of these, all but IYSV have been previously reported in the state of Florida. More information about tospoviruses can be found in Tospoviruses (Family Bunyaviridae, Genus Tospovirus) (http://edis.ifas.ufl.edu/pp134). -- from PP306, Tomato Chlorotic Spot Virus

Zika Virus

This page lists useful information about the Zika virus. The primary focus of the science-based information and recommendations to be found here are ways you can reduce your exposure to mosquito bites and ways you can reduce the mosquito populations around your home and neighborhood.

Good sources of information about the disease in humans are the CDC, MedlinePlus and NIH.

For current University of Florida information including communications, prevention tips, resources, and research, see the UF Zika Prevention website at http://zika.ufl.edu.
