Mpox (pronounced “em-pox”) is an infectious disease that’s transmitted through close contact and causes a rash on various parts of the body. The mpox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Mpox symptoms are similar to smallpox symptoms but milder. It is rarely fatal, and most people recover without treatment in a few weeks.

Public Health Resources

Public Health Resources

During an emergency, local, state and national public health agencies will have the most up-to-date information and resources available to your local community.

Bookmark these agencies for ongoing updates as public health situations emerge and evolve:


These charts track the prevalence and concentration of viral sequences in San Francisco wastewater taken at the San Francisco Southeast Wastewater Treatment Plant. If you need charts specific to COVID-19 infection rates at UCSF, please see our COVID-19 dashboard.

How Wastewater Tracking Works


Asymptomatic and symptomatic people shed viruses


The viruses are excreted in feces


Feces are transported to the sewage system


Wastewater samples are taken at the sewage treatment plant


The wastewater is analyzed for viral sequences


The data is shared to inform public health actions


SARS Coronavirus 2 (SARS-CoV-2 or COVID-19) Concentration in San Francisco Wastewater

The following graph shows the relative number of SARS-CoV-2 viral copies present in wastewater samples compared to levels of a common plant pathogen known as pepper mild mottle virus (PMMoV). PMMoV is used as a baseline to normalize against other viral pathogens. Increases or decreases in SARS-CoV-2 viral copies in wastewater can be correlated with overall case numbers in a population. The Y-axis represents number of viral copies, and the X-axis represents the week of sample collection, with the date corresponding to the last day of that week. Download the source data
