Health care facilities are crucial in controlling the spread of infections. It is because every inch of a healthcare facility can transmit infection. The cleaning and disinfection of the health care facilities are thus extremely crucial. Cleaning helps to clear the microbial contamination from the surfaces. On the other hand, we are aware that cleaning is not enough. Disinfection and sanitation are more thorough. They get rid of the microorganisms that remain even after cleaning.

What are health care facilities?

Health care facilities are institutions that provide medical aid to patients. During emergencies, health care facilities receive a large number of patients. These patients often suffer from diseases. For instance, these days, health care institutions mostly consist of COVID-19 patients. Examples of health institutions include:

  •  Hospitals
  •  Primary health care centers
  •  Isolation camps
  •  Burn units
  •  Feeding centers

The importance of disinfection and sanitation of the health care facilities

According to the CDC, health care facilities can harbor microorganisms. These microorganisms are harmful to the patients as well as visitors. Therefore, such an environment is quite risky for patients. Disinfection and sanitation on a routine basis help in reducing the risk. Approximately 30 to 40% of the infections are by the hands of health care workers. Apart from these, other non-critical surfaces can cause secondary infections. Non-critical surfaces include bedside tables and railings. This is why sanitation and disinfection are essential processes.


Recommendations for the sanitation and disinfection of health care facilities

CDC and WHO draft guidelines relevant to health. They have given us guidelines that help in controlling the spread of infection. A breakdown of these guidelines are as follows:


Sterilization is killing off the microorganism. However, sterilization does not always guarantee this. However, it is more effective than cleaning. According to guidelines, it kills 99.9999% of the microorganisms. You can sterilize an object by chemical and physical means. Physical means include the application of heat or radiation. Chemical sterilization is with the help of chemicals such as ethylene oxide.


EPA registered disinfectants are most common in health care facilities. These disinfectants are rapid-acting and non-toxic. It is important to dilute the disinfectant according to the directions by the manufacturer. Disinfectants can kill bacteria, fungi as well as viruses.

CDC recommends disinfecting all the health care equipment and also those areas which can cause secondary infection. The process of disinfection should take place regularly. This frequency can be daily or thrice a week. It is also preferable to replace mopping solutions with adequate disinfectant solutions.


A review of the guidelines shows that disinfection is the preferred method. It is vital to practice caution when preparing dilutions of disinfectant. Furthermore, do not use disinfectants on infants, bassinets, or incubators. It is important to note that cleaning of non-patient areas with detergent and water is enough. It includes the administrative areas of the health care facilities. Special care and instructions are important during the disinfection and sterilization process. Inadequate practices are ineffective and may aggravate the problems within the facility.

Viruses and bacteria are not that easy to get rid of. Therefore, CDC recommends that you clean as well as disinfect your house. Before starting this process, you should be aware of the high touch surfaces. People can contaminate these surfaces. Hence, they require cleaning and disinfection much more frequently.

Examples of High Touch Surfaces Include:
  •  Doorknobs
  •  Counters

You are the only one who is aware of your homes. Pay close attention to the types of surfaces in your homes. Also, note the different surfaces that come in contact most frequently.


Before starting the cleaning process, wear disposable gloves. Routinely clean your house with soap and water. Create a schedule for cleaning the house. Mainly include high touch surfaces during this routine.


CDC recommends that you use EPA registered disinfectants for this purpose. However, the below-mentioned household disinfectant agents are easily available.

Household bleach solution

To use bleach for disinfection, you will need to dilute it first. For making a dilution mix 5 tablespoons of bleach for every gallon of water. Allow proper ventilation in the room during disinfection. You will have to leave the bleach solution for a minute on the surface.

Alcohol solution

Read the manufacturer’s label. If it is 70% alcohol, then you will not have to dilute it. On the other hand, if it is concentrated alcohol, then dilution is necessary. To make 70% dilution mix 70mL of alcohol and 30mL of water.

  •  Always make sure that you wear disposable gloves.
  •  Always make sure that the area you are about to disinfect is properly ventilated.
  •  Always make sure to wash your hands after disinfecting the house.
  •  Always make sure that you do not touch your eyes, nose, or mouth without washing your hands.
  •  Always read the instructions before using any type of chemical for disinfection.
  •  Always make sure that you dispose of the contaminated gloves in a separate trash bag.

The disinfection of the house is the most important thing to do. It is important to protect your loved ones from getting ill. However, you can always get help from professional services to assist you with the process.

We all know about the recent COVID-19 pandemic. Being in a pandemic is scary for many of us out there. The media, medical, and government officials have all asked us to remain indoors, not to touch our face, and to wash our hands regularly.

Due to social distancing and protecting yourself and others around you, people are now seen wearing masks. These masks are of different make and material. Very few people are aware of what type of mask to wear. Let us first discuss the different types of masks available on the market.


The main reason to wear a mask to protect our nose and mouth from the virus. It means that it protects us from the sneeze and cough droplets of a sick person. Wearing a mask prevents the droplets from landing on surfaces and other people. However, not all masks are useful for this purpose. Let us have a look at what is best during the pandemic

  1. Homemade masks

These masks are those made out of cloth. Many people are teaching how to make masks at home. However, are these effective? CDC recommends that you can wear cloth masks in a public environment. It applies the same for a place where people cannot maintain social distance. You must wash this mask regularly.

  1. Surgical masks

These are green colored three-ply masks available in the market. You must have seen doctors wearing them all the time. Sick people and their caretakers must wear these masks at all times. It protects the sick people from spreading the germs to healthy ones. However, an ill-fitted surgical mask can allow the virus to enter your airway.

  1. N95 respirator

Health care workers must wear this mask at all times. This is because of their constant exposure to sick people. It blocks 95% of the germs from entering into the airway.


Studying about the masks, we know that N95 masks are the best options. However, the CDC recommends that the public should not use these masks. It is because of the shortage of N95 masks for health care workers. It is also essential to know the right practices to wear and remove the mask to make it more effective. Remember that not wearing a mask the right way, always leaves a chance to contract an infection.


Wash your hands before wearing a mask. Fix the loops on your ears. Bend the metallic strip (if available) over the bridge of your nose to fit it. Pull the mask so that it completely covers your chin. Make sure that your masks fit perfectly. Do not touch the mask after it is in position. Replace the mask after a day.

When you wish to remove the mask, wash your hands. Never touch the mask. You can handle it from the loops. Dispose of the used masks in a covered trash can and wash your hands.


If you follow these steps, then there is a high chance that you will not be one of the patients during this pandemic.

  •  Stay at home. We cannot emphasize this enough. Only leave your homes in case of emergency
  •  Wash your hands with soap and water. An alcohol-based sanitizer can be an alternative to washing your hands.
  •  Do not touch your eyes, nose, or mouth with dirty hands.
  •  Wear a mask in public settings.
  •  Maintain social distance in public settings.
