When the pandemic started, we saw a similar situation with hand sanitizers. Although the Centers for Disease Control and Prevention (CDC) knows that it is best to wash hands with soapy water, they recommend using hand sanitizer as a reliable option when the sink is difficult to use. As a result, a large amount of hand sanitizer was sold, and almost every store was out of stock. Seeing this demand, many companies quickly began to manufacture and sell hand sanitizer. It quickly became apparent that not all products were created equally, which led the FDA to severely criticize inferior disinfectant solutions. Consumers are now advised to avoid using hand sanitizers because they are ineffective or may cause harm.

They are valuable tools for patients and providers who coordinate to track blood oxygenation in the treatment of certain chronic lung and heart diseases. They are usually introduced in medical institutions and are a tool for reporting overall disease management. During a pandemic, they can even be advised to conduct self-monitoring under the guidance of your healthcare provider to monitor COVID-19-related symptoms.

Symptoms that need attention include chest pain, severe shortness of breath, and disorientation. These methods can assess a person’s feelings and behavior, and then provide guidance for next steps, such as seeking emergency care, calling your healthcare provider, or continuing to monitor symptoms, all of which can help people guide through the collaborative treatment process.


Please keep in mind that we do not yet have a vaccine or targeted treatment for COVID-19. The best action you can take to protect the health of yourself, your family and your community is to prevent the spread of disease by washing your hands, wearing a mask, maintaining social distancing and staying at home as much as possible-especially if you feel unwell or in People who are infected with COVID-19.
