Coronavirus Disease 2019 (COVID-19), renamed by the World Health Organization on February 11, 2020, is a respiratory illness caused by a novel, or new, coronavirus first identified in Wuhan, Hubei Province, China.
Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with MERS, SARS, and now with COVID-19.
A novel coronavirus is a new coronavirus that has not been previously identified. COVID-19 is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.
Because this novel coronavirus is a strain that had previously not been found in humans, its health impact is currently being closely monitored internationally, nationally, and locally, by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC).
Older adults and those with chronic underlying medical conditions appear to be at high risk for serious complications.
Some infected individuals never show symptoms.
Per the Centers for Disease Control and Prevention (CDC), the novel coronavirus is thought to spread mainly through close contact from person-to-person. Some people without symptoms may be able to spread the virus. The virus that causes COVID-19 is spreading very easily and sustainably between people.
The most current information can be found on the Caltech COVID-19 Dashboard, which will be updated every weekday by 2 p.m. PDT.
Given the growing number of cases in Los Angeles and in California, as well as increased testing availability and frequency, we must be prepared for additional confirmed cases of COVID-19 in the Caltech community. Caltech will continue to work with local public health officials to monitor this situation and expeditiously contact individuals who may be at risk of exposure. The broader community will be updated about Caltech's ongoing response to the pandemic through the Caltech Coronavirus website and through Ion Caltech.
Caltech is actively monitoring and adapting to this rapidly evolving situation. For specifics about our response, please see the information at the top of our main COVID-19 page.
- Wear a face covering that covers your nose and mouth. (See: Institute Guidelines on Face Coverings )
- Maintain 6' of physical distance between yourself and anyone outside of your immediate household, whether indoors or outdoors. Wearing a face covering does not negate the need for physical distancing.
- Wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer.
- Clean and disinfect shared surfaces and objects that are touched frequently (e.g. doorknobs, desks, phones).
- Get a flu shot. We strongly recommend that everyone obtain seasonal flu vaccination. While there is no vaccine currently to prevent COVID-19, influenza is currently in widespread circulation in California, and initial symptoms can be similar to COVID-19. Any illness right now can increase anxiety and concerns.

In accordance with guidelines from the Centers for Disease Control (CDC) and state and local orders, Caltech requires that everyone including visitors, vendors, and contractors on the campus and off-site locations properly wear a cloth face covering that fully covers their nose and mouth at all times when in buildings or outdoors.
Face coverings with one-way valves may not be used as they are not effective for source control; such coverings may allow the wearer's respiratory droplets to spread.
Wearing a face covering supplements, but does not replace, physical-distancing requirements. All faculty, staff, students, and visitors should continue to maintain at least 6-feet of distance from others while onsite. If wearing a face covering impedes your ability to complete a job or task, you should contact your supervisor or adviser for evaluation of alternative solutions.
