Infection Control in Coronavirus Departments
Precautionary measures to protect the medical staff
The medical staff working in the coronavirus departments are at the highest risk for getting COVID-19, especially after the number of infections among doctors, nurses, and other teams working in those departments has spiked. They are like soldiers in a battle fighting this deadly and rapidly spreading virus.
There are infection control programs and international protocols in place that require the application of precautionary measures to limit the spread of infection within the hospital. The focus on these programs has increased recently in the coronavirus departments, especially since respiratory infection is the second most common hospital infection and the first most common infection within ICUs.
To prevent infection, standard precautions are the minimum infection prevention practices that apply to all patient care, regardless of suspected or confirmed infection status of the patient, in any setting where healthcare is delivered. These practices are designed to both protect DHCP and prevent DHCP from spreading infections among patients. Standard Precautions include hand hygiene, use of personal protective equipment (e.g., gloves, masks, eyewear), respiratory hygiene / cough etiquette, sharps safety (engineering and work practice controls), safe injection practices (i.e., aseptic technique for parenteral medications), sterile instruments and devices as well as clean and disinfected environmental surfaces.
The hospital environment, whether rooms or corridors, should be sterilized to prevent virus transmission, and here we must emphasize the need to sterilize doorknobs, elevator buttons and office surfaces because they are the primary driver for infection.
Handwashing is the first step
Infection control programs focus primarily on the hands, as they are the primary source of transmission of infection and germs, which requires washing them in the best way recommended by the World Health Organization.
Cleaning, sterilizing and disinfecting hands before and after dealing with the patient, especially when taking samples, is the first procedure to stop and prevent the risk of cross-infection, and it is crucial for everyone working in the health facility to follow it, as it has been shown that washing hands contributes to reducing infection cases in hospitals by up to 50 percent.
The importance of hand hygiene urged the World Health Organization to celebrate Hand Hygiene Day given its role in preventing the transmission of infections. Hand hygiene is one of the most important measures that prevent the spread of infection in hospitals, and it is a general term that includes washing hands with soap and water, using disinfectants by rubbing them with alcohol and disinfecting them in preparation for surgical procedures.
Medical teams and healthcare providers follow the seven handwashing steps in order not to neglect any area during handwashing and ensure that their hands have been thoroughly cleaned and sterilized. But handwashing in hospitals must be done in a specific technique that guarantees getting rid of germs, and this technique is as follows:
1. Wet hands with water and apply single shot of soap
2. Rub hands palm to palm
3. Rub back of each hand with the palm of other the hand with fingers interlaced
4. Rub palm to palm with fingers interlaced
5. Rub with backs of fingers to opposing palms with fingers interlocked
6. Rub each thumb clasped in opposite hand using rotational movement
7. Rub tips of fingers in the opposite palm in a circular motion
8. Rub each wrist with the opposite hand
9. Rinse hands with water and dry thoroughly
Healthcare workers must follow a stricter handwashing process as recommended by WHO:
- Before touching a patient,
- Before clean/aseptic procedures,
- After body fluid exposure/risk,
- After touching a patient, and
- After touching the patient surroundings
Knowing how to wash your hands properly is an important step in preventing the spread of infections in the workplace, home or schools. Also important is knowing when to wash your hands.
Here are the key times when handwashing should be conducted:
- At the end of each work/school period
- Before each break
- Before eating or preparing food
- After going to the restroom
- Whenever hands are dirty or contaminated
The COVID-19 outbreak has increased medical waste all across the world and it has also led to a huge amount of face masks and medical waste. In particular, another aspect of the spread of COVID-19 is improper solid waste management. If waste is not managed properly, it may lead to the spread of the virus. Consequently, the number of confirmed cases has rapidly increased and the amount of medical waste associated with COVID-19 has also significantly increased.
According to the World Health Organization (WHO), infectious waste is defined as waste contaminated with blood and other bodily fluids, cultures and stocks of infectious agents from laboratory work, or waste from patients with infections. But WHO interim guidelines suggest all healthcare waste produced during patient care, including those with confirmed COVID-19 infection, is considered as infectious medical waste, but the waste generated in waiting areas of healthcare facilities can be classified as
