Monkeypox (Mpox/MPX) Information

About Monkeypox (Mpox/MPX)

Monkeypox (Mpox/MPX) is a rare disease that is caused by infection with the Mpox virus. Mpox belongs to the Orthopoxvirus genus which includes the vaccinia virus which is used in the smallpox vaccine, variola (smallpox), and other pox viruses generally limited to animals. Mpox is currently of public health concern because while sporadic cases have popped up in the past, associated with residence or travel in endemic areas, its emergence in non-endemic areas and transmission human-human is new.  Mpox is less transmissible and usually far less severe than smallpox, and far less transmissible than other viruses such as chickenpox, measles - and COVID.

Over the last few months there has been an increase in reported cases where Mpox is not commonly seen, including in Europe, Canada, the United States, and California. While it's important to stay alert about any emerging public health outbreaks, the current risk of getting monkeypox in the general public is very low.   


Monkeypox (Mpox/MPX) might start with symptoms like the flu, with fever, low energy, swollen lymph nodes, and general body aches. Within 1 to 3 days (sometimes longer) after the appearance of fever, the person can develop a rash or sores. The sores will go through several stages, including scabs, before healing. They can look like pimples or blisters and may be painful and itchy. 

The rash or sores may be located on or near the genitals (penis, testicles, labia, and vagina) or anus (butt) but could also be on other areas like the hands, feet, chest, and face. They may also be limited to one part of the body. 

People with Mpox may experience all or only a few of these symptoms. Most will develop rash or sores. Some people have reported developing a rash or sores before (or without) the flu-like symptoms. Mpox can spread from the time symptoms start until all sores have healed and a fresh layer of skin has formed. This can take several weeks. 


Mpox spreads primarily through direct contact with infectious sores, scabs, or body fluids, including during sex, as well as activities like kissing, hugging, massaging, and cuddling. It can spread through touching materials used by a person with Mpox that hasn’t been cleaned, such as clothing and bedding. It can also spread by respiratory secretions during prolonged, close, face-to-face contact.    

  • Mpox can be spread through: 

    • Direct skin-skin contact with rash lesions 

    • Sexual/intimate contact, including kissing  

    • Living in a house and sharing a bed with someone 

    • Sharing towels or unwashed clothing 

    • Environmental surfaces, particularly when in dark, cool, and low humidity environments  (i.e. bathrooms, showers, toilet seats).
    • Respiratory secretions through prolonged face-to-face interactions (the type that mainly happens when living with someone or caring for someone who has monkeypox) 

  • Mpox is NOT spread through: 

    • Casual brief conversations 

    • Walking by someone with Mpox, like in a grocery store  


There are number of ways to prevent the spread, including: 

  • Always talk to your sexual partner/s about any recent illness and be aware of new or unexplained sores or rashes on your body or your partner’s body, including on the genitals and anus 

  • Avoiding close contact, including sex, with people with symptoms like sores or rashes 

  • Practicing good hand hygiene

  • People who become infected should isolate themselves until their symptoms are improving or have gone away completely.  The rash should always be well covered until completely healed.

  • Using appropriate personal protective equipment (PPE) (like a mask, gown, and gloves) when caring for others with symptoms 

  • Avoiding contact with infected materials contaminated with the virus 

  • Avoiding contact with infected animals 

What to do if you have had an exposure or symptoms

If you have had an exposure, have symptoms you are concerned about, or otherwise need to speak with someone about your risk, please reach out to your primary care provider for a phone or video appointment. 

  • Students can do this via eTang or by calling the 24/7 Nurse Advice Line at (510) 643-7197. 
  • Faculty and staff should reach out to their primary care provider. 


Supplies of JYNNEOS, the monkeypox (Mpox) vaccine, are currently very limited nationally but are expected to increase over the next month.  Health department websites and social media are the best resources at this time; UHS will update this website as we become aware.  Please share any news by emailing!

(updated 8/29/22) University Health Services is starting to get a more regular supply of Mpox vaccines and has vaccine appointments available a few days each week that can be self-booked on eTang for those that meet the vaccine criteria.  

Upcoming dates for Mpox vaccine appointment:

  • October: appointments are on Wednesdays and Fridays and can be booked on eTang.

We are currently reserving for students who are identified as close contacts (CDPH Tier 1, below) or individuals at high epidemiological risk (CDPH Tier 2).

  1. Post-Exposure Prophylaxis (PEP) for known close contacts of Mpox cases who are identified by public health via case investigation, contact tracing, and risk exposure assessments.

  2. Post-Exposure Prophylaxis (PEP)++  for individuals with certain risk factors who are more likely to have been recently exposed to Mpox even if they have not had documented exposure to someone with confirmed Mpox, such as people who attended an event or venue where there was known Mpox exposure.

  3. Pre-Exposure Prophylaxis (PrEP) for individuals at occupational risk of Mpox according to Advisory Committee on Immunization Practices (ACIP) guidance, including laboratory workers who perform Mpox testing, and clinical and public health workers who collect Mpox specimens.

Please note: if you already have symptoms of Mpox, you cannot receive the vaccine. 

As supplies become more available, we will be publicizing more broadly, hopefully, within the next few weeks  Check back frequently!

Faculty and staff should check with their primary care provider for vaccine availability, or seek vaccination at a community site.
