- Coronavirus disease 2019 or COVID-19 is a new respiratory virus first identified in Wuhan, Hubei Province, China.
- Coronaviruses are a large family of viruses. There are several known coronaviruses that infect people and usually only cause mild respiratory disease, such as the common cold.
- You can learn more about COVID-19 at the CDC website.
- Monitoring and testing are ongoing across the United States.
- A nationwide case count table is available on the CDC website.
- A statewide case count table, including confirmed cases in Maricopa County, is available on the Arizona Department of Health Services website.
- This is a rapidly evolving situation.
- Please visit Maricopa.gov/coronavirus for the most up-to-date and accurate information about what is going on in Maricopa County.
- Please visit the CDC website for the most up-to-date information nationally.
COVID-19 is thought to spread mainly through respiratory droplets produced when an infected person coughs, sneezes, or talks.
- COVID-19 spreads similar to flu; therefore, if you are in close contact to someone who is actively sick with COVID-19 for an extended period of time, you are at an increased risk of getting sick.
- For example, closer than 6 feet to a sick individual for more than 10 minutes.
Symptoms reported for patients with COVID-19 have included fever or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea.
Most people who contract COVID-19 will experience mild symptoms. Among adults, the risk for severe illness from COVID-19 increases with age, with older adults at highest risk. There are also other factors that can increase your risk for severe illness, such as having underlying medical conditions, including heart, kidney or lung disease, diabetes, and obesity. Severe illness means that the person with COVID-19 may require hospitalization, intensive care, or a ventilator to help them breathe, or they may even die.
There is no specific antiviral treatment recommended for COVID-19. People with COVID-19 will receive supportive care to help relieve symptoms.
In light of the rapid growth in positive COVID-19 cases, the Maricopa County Board of Supervisors unanimously approved regulations related to wearing masks countywide effective June 20, 2020. The mandate creates consistent minimum mask-wearing requirements across all jurisdictions while allowing cities and towns to set their own policies and regulations related to face coverings.
Here are some things to know generally about wearing a face covering:
- The general public should wear a cloth face covering or mask. Unless you are working in a healthcare setting, you should not wear medical grade masks or respirators to protect yourself and others from COVID-19.
- While wearing a cloth face covering or mask, make sure it fits properly and that it is secure around your mouth and nose, but still allows you to breathe normally.
- Do not re-use a disposable mask and always change it as soon as it gets damp.
- Face coverings should not be worn by children under age 2 or those who have trouble breathing, any inability to tolerate wearing it, or if they are unable to remove it without assistance.
Yes, cloth face coverings or masks are safe to wear.
Although cloth face coverings or masks can feel uncomfortable or unusual, especially if you’re new to wearing them, medical experts say they do not lead to carbon dioxide intoxication or oxygen deficiency and are safe to wear for long periods of time.
The Centers for Disease Control and Prevention (CDC) has advised using cloth face coverings or masks for the general public to reduce the chance of getting COVID-19. Wearing a cloth face covering or mask also decreases your chance of spreading COVID-19 to others, especially when you cannot be at least 6 feet away from other people.
Some people with pre-existing respiratory illnesses (like asthma, emphysema or COPD), might have difficulty breathing when using certain types of tightly fitting masks, called respirators. If you have concerns about wearing a mask due to a medical condition, please talk with your healthcare provider about whether you should wear a cloth face covering mask.
No. “Face mask exempt cards” that reference the U. S. Department of Justice and/or the Americans with Disabilities Act (ADA) are fraudulent. The ADA website has more information on these fraudulent materials.
Individuals who have concerns about whether they should wear a cloth face covering or mask due to their underlying medical conditions should consult their healthcare provider for individual recommendations.
Yes, masks help contain respiratory droplets that carry the virus, which makes us less likely to infect others.
COVID-19 is transmitted through respiratory droplets when an infected person talks, coughs, or sneezes. These droplets can fly through the air and land in another’s person’s mouth or nose up to 6 feet away. When used with social distancing, cloth face coverings or masks can provide an extra layer to help prevent the respiratory droplets from traveling in the air and onto other people.
There is evidence that cloth masks made of household materials provide about 60% filtration of particles of droplet size (range from 3-86%) from coming into contact with the person wearing a cloth face covering or mask. There is also a lot of evidence that masks keep particles inside the mask (called “source control”), which is important due to the high number of people with COVID-19 who do not have symptoms.
At this time, there is no evidence that animals play a significant role in spreading the virus that causes COVID-19.
Based on the limited information available to-date, the risk of animals spreading COVID-19 to people is considered to be low. A small number of pets have been reported to be infected with the virus that causes COVID-19, mostly after they have had contact with people with COVID-19.
Pets have other types of coronaviruses that can make them sick, like canine (dog) and feline (cat) coronaviruses. These other coronaviruses cannot infect people and are not related to the current COVID-19 outbreak.
However, since animals can spread other diseases to people, it’s always a good idea to practice healthy habits around pets and other animals, such as washing your hands and maintaining good hygiene. For more information on the many benefits of pet ownership, as well as staying safe and healthy around animals including pets, livestock, and wildlife, visit CDC’s Healthy Pets, Healthy People website.
People of all ages can be infected by the virus that causes COVID-19. In Maricopa County, approximately 10% of COVID-19 cases to date have been among ages 0-19.
While some children and infants have been sick with COVID-19, adults make up most of the known cases to date. Risk for severe illness from COVID-19 increases with age, and even more for those who are immune-suppressed or have underlying health conditions such as heart disease, kidney or lung disease, obesity, or diabetes.
CDC and partners are investigating cases of multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19. Learn more about COVID-19 and multisystem inflammatory syndrome in children (MIS-C).
According to CDC, it is not yet fully known whether weather and temperature affect the spread of COVID-19. The virus that causes COVID-19 is new, and we’re still learning about it.
Some other viruses, like those that cause the common cold and flu, spread more during cold weather months but that does not mean it is impossible to become sick with these viruses during other months. There is much more to learn about the transmissibility, severity, and other features associated with COVID-19, and investigations are ongoing.
As we have seen here in Maricopa County, you can catch COVID-19 no matter how sunny or hot the weather is. Cases reached new high levels during June when temperatures were into the 100s.
Maricopa County daily counts may vary slightly from state reporting due to differences in data reporting download times. Maricopa County reports daily data for confirmed COVID-19 cases (people with positive PCR or antigen tests), and the state is also including probable cases.
County public health investigators are responsible for following up on cases reported to public health to collect additional data such as symptoms, severity of illness (i.e., whether they were hospitalized), demographic information, and possible exposures to others.
