We all are well familiar, how Covid-19 has dominated all areas of the world by emerging first in China. In the history of epidemiology, the period of this virus is the most active one. Merely starting from Wuhan, this virus trespassed all around the globe.

This pandemic has affected everyone's life in many aspects. Many countries declared lockdown to keep people staying at home to control this pandemic. Similarly others measures were also taken to slow down its spread by the travel ban, closing of schools and other institutes etc. As we know that things are getting back to many normal countries have lifted the lockdown, and public places have been reopened, it is essential to understand how to prevent this virus from spreading and protecting ourselves. 


How Covid-19 spreads?

There are several ways by which this virus spreads. It has a person to person transmission through aerosols or droplets, airborne mode, surface transmission, and faecal-oral transmission. It applies when a person has no idea about its contact with the infected one at the community level. Moreover, few pets have also been infected by their contact with humans and then act as a virus source for others.

In which places COVID-19 circulates the most

 Covid-19 spreads the most in closed, confined and crowded places, it is noteworthy that it spreads more in indoor rather than outdoor spaces. Poorly ventilated and closed spaces provide a favorable place for contagious spread of the virus. Therefore, overcrowded spaces such as cinemas, theatres, wedding halls, churches, mosques etc. are the common places where COVID-19 spreads the most. Therefore, it is necessary to avoid public gathering in these palaces to protect oneself from contracting this viral pneumonia.

Protective measures to prevent Covid-19!

Several measures prevent virus spread by wearing masks, maintaining a distance from others, properly cleaning your hands with soaps and sanitizers, covering mouth while sneezing coughing, and staying home to avoid any exposure.


Role of Sanitizers in this pandemic!

As this novel virus grew, the uses of sanitizers have reached its highest level. All online stores and market shops had a lot of business by selling a tremendous amount of sanitizers. This has played a role to avoid serious health challenges of people. One is frequent and effective hand washing of the many ways implemented to reduce the virus's spread.


Effectiveness of hand sanitizers in killing virus

Sanitizers have a significant role in protecting against the virus, but it is not the first-line defense against the virus. Properly washing your hands for around 20 seconds is recommended. Sanitizer, with about 60 % of alcohol, is highly effective. Coronavirus is termed as "enveloped viruses "which means they have an outer envelope killed by sanitizers with high alcohol content ranging from 60 to 95 % alcohol.


Types of sanitizers

There are two large categories which include:

  1. Alcohol-based sanitizers
  2. Non-alcohol based sanitizers:


Alcohol-based sanitizers: These are a bit harsh on hands when used compared to non-alcohol ones but are more beneficial in health. They have a combination of alcohol, n-propanol, isopropyl alcohol, water and also humectants. They are used predominantly in the health care setting because of their low cost and high efficacy,


Non-alcohol-based sanitizers: Benzalkonium chloride is the most active ingredient of these sanitizers, commonly used as a disinfectant. These are less irritating than alcohol ones but may tend to cause dermatitis in some individuals.


How to select your sanitizer?

 Given the popularity of hand sanitizers in this pandemic wide range of sanitizers, different ingredients and delivery modes are available. Similarlyalcohol-based sanitizers are available in various sizes and components. Read the contents of your sanitizer correctly, which shows labels like ethanol, isopropanol, ethyl alcohol etc. Never choose those sanitizers labelled as alcohol-free. Alcohol-based sanitizers are an effective alternative to hand washing by soaps to prevent bacterial and viral spread.


The proper way to use Sanitizers:

The best way is to cover your hands thoroughly with sanitizers instead of just dabbing a little sanitizer on your hand, rubbing them properly until it gets dry and then washes it off. This procedure takes around 20 seconds which is not more than health. You should do this practice several times a day, especially when you enter a home after coming back from any place. You should take care while dealing with alcohol-based products to avoid touching your eyes, supervise your children while using them and store them out of reach of your children.

 Role of wristbands in Covid-19!

Maintaining hygiene by washing and cleaning hands properly for disease prevention has its attributes in this pandemic. However, new technology has emerged, which has facilitated us through the use of wristbands. Such disinfecting wristbands work not only on the wearer's hands but also on the objects that come in contact with the wearer.

 How wristband works!

This band has an electronic system that emits ultraviolet rays on the person wearing it and any object near it. Internally, it has a cylinder composed of coils and solar cells on the outside of it. The electronic emitter positively controls the intensity of UV rays emission and the direction of its spread. The hand movement provides the electrical energy that moves the coils and charges the capacitor, which charges the emitter to emit rays in different directions and disinfect hands and other nearby objects.

 Challenges in its use!

This new technology on one side is unique and beneficial in one's protection, but on the other hand, it also has Its challenges. This is the latest research and works to get it much better and minimise any hazardous effects on the human body. Many areas still have to cover, including determining its frequency of disinfection and optimal duration of action not to affect the user’s hands and skin. Others parameters like the range of rays to disinfect objects and which dimensions are safe to use so that rays do not affect other people in proximity has its challenges. Last but not the least cost of this new technology is also a crucial challenge. It is essential to maintain this at a low price to be accessible to others who are non-affording, and as many people can have benefited from this new miracle.


Thus, in the present demands of constant hygiene, some essential accessories are becoming a hit. These not only kill harmful organisms but also are an additional form of immune support. These are indeed the real treasure that we have at this time.!
