What is COVID-19
COVID-19, the latest global pandemic, is a coronavirus disease that causes respiratory illness that can spread quickly from human to human. The latest outbreak of COVID-19 caused about 7,000 confirmed cases in China in the first month (January 2020, Situation report), following with another 80,000 confirmed worldwide in the second month (February 2020, Situation report).
Difference between COVID-19, MERS and SARS
Coronaviruses are a wide family of viruses that cause disease, often in animals. However, 7 forms of coronaviruses can cause disease in humans, and 3 of these can cause significant outbreaks of deadly pneumonia:
- COVID-19 – It is an infectious disease caused by the most recently identified coronaviruses. The “SARS-CoV-2 virus” is a novel coronavirus that was first identified in Wuhan, China at the end of 2019 as a disease with extreme acute respiratory syndrome that actively spread worldwide in 2020.
- MERS – The Middle East respiratory syndrome is a viral respiratory disease caused by coronavirus. The virus “MERS-CoV” was first identified in Saudi Arabia in 2012.
- SARS – The virus “SARS-CoV” was reported in 2002 as the cause of an outbreak of severe acute respiratory syndrome (SARS).
According to figures from the World Health Organization (WHO), SARS and MERS took years to spread and killed more than 800 people. Yet COVID-19 took just 3 months to spread around the world, causing about 115,000 deaths worldwide. Such high numbers that have occurred in a short time can cause the local medical resource to crash.
How to ensure protection level sufficient for healthcare personnel
According to WHO guidelines, the virus can spread directly when a case of COVID-19 coughs or exhales droplets that touch the nose, mouth or eyes of another person. Keep your hands clean and cover your mouth and nose while coughing or sneezing is vital for public health. Yet it’s another matter for healthcare services.
In order to prevent mass infection in healthcare facilities, infected patients need to remain in a controlled environment, namely negative pressure isolation room. Frontline operators need to wear a complete range of isolation equipment, like face shield, N95 respirator, coverall, gloves, boot covers, etc. according to WHO Disease Commodity Packages (DCPs) of COVID-19, or CDC Coronavirus Disease Infection Control.
Is it enough if wear all the equipment suggested? Typically, environmental variables are under-controlled in a healthcare facility. Normally, biological threats come from a few directions, usually from the lower front, since the patient can sit or lie down on the bed. Protective equipment used in the medical industry, such as isolation gown, is intended to avoid front contamination only. But the region above or below the chest is exposed and can cause possible hazards. Once it comes to coronavirus disease, such as COVID-19, protection for the human body is not enough.
In order to get an appropriate protection, coverall is a safer choice when dealing with disease prevention, such as COVID-19. Coverall has a one-piece hood, gloves, body cover and pants that eliminates all gaps in the collar, chest, legs and back section. These will have 360 degrees of protection for healthcare personnel.
