Coronaviruses are a type of virus. There are many different kinds, and some cause disease. A coronavirus identified in 2019, SARS-CoV-2, has caused a pandemic of respiratory illness, called COVID-19.
Tracking COVID-19 in California by link:
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.
Most people infected with the virus will experience mild to moderate respiratory illness and recover without requiring special treatment. However, some will become seriously ill and require medical attention. Older people and those with underlying medical conditions like cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop serious illness. Anyone can get sick with COVID-19 and become seriously ill or die at any age.
One thing we know for sure about SARS-CoV-2, the virus that causes COVID-19, is that it is changing constantly. Since the beginning of the pandemic, we’ve seen a number of prominent variants, including Alpha, Beta, Delta, and Omicron.
Although new variants are an expected part of the evolution of viruses, monitoring each one that surfaces is essential in ensuring we—in the U.S. and globally—are prepared. This is especially true if a new variant is more aggressive, highly transmissible, vaccine-resistant, able to cause more severe disease—or all of the above, compared with the original strain of the virus.
COVID-19 symptoms include:
Some people infected with the coronavirus have mild COVID-19 illness, and others have no symptoms at all. In some cases, however, COVID-19 can lead to respiratory failure, lasting lung and heart muscle damage, nervous system problems, kidney failure or death.
If you have a fever or any of the symptoms listed above, call your doctor or a health care provider and explain your symptoms over the phone before going to the doctor’s office, urgent care facility or emergency room. Here are suggestions if you feel sick and are concerned you might have COVID-19.
Our dental practitioners take appropriate personal protective measures against different types of patients, including wearing goggles, masks, gloves, disposable protective clothing, etc.in correct order, to achieve the best protective effect and minimize the risk of infection during the spread of COVID-19.
The non-emergency dental treatment of the confirmed patients should be delayed. They could make an appointment for dental treatment after the COVID-19 treatment with a negative nucleic acid test. For dental emergencies of the confirmed patients, dental personnel need to take advanced protection and place the patients in a negative pressure dental treatment room in a contaminated isolation area with a portable HEPA filter or anti-splash isolation device. Under the condition of not affecting the treatment effect, dentists should give priority to performing necessary non-invasive or minimally invasive dental procedures with manual instruments, try to avoid aerosol generation steps such as using ultrasound machines and air water syringes, and shorten the treatment time.
After the treatment, the room and equipment should be cleaned and disinfected strictly in accordance with infection control guidelines for dental facilities. The dental assistant flush water pipeline with chlorine disinfectant, clean the surfaces of the objects with quaternary ammonium salt and disinfectant wipes, clean the floor with chlorine disinfectant, spray air with 2% peracetic acid and turn on the ultraviolet light for more than an hour. Dental personnel should delay admission to the negative-pressure dental clinic to treat another confirmed patient, until the potentially infectious droplets and particles are removed.
