Sir,

Since Pandemic COVID-19 began, disinfecting and hands washing with soap or alcohol-based hand rubs (ABHRs) have been among the most economical, easiest, and essential measures to prevent the virus spread. Both methods, hand washing or the use of ABHRS, have proven their effectiveness on SARS-CoV-2 ( severe acute respiratory syndrome coronavirus 2). After 4 months of using these products, several side effects have been reported, especially for health workers. In this article, we will try to deduce some recommendations for hand hygiene (Table 1), useful especially as summer begins.

Table 1: Recommendations                                                                  

SOAP

Over the years, handwashing with soap and water has been considered a measure of personal hygiene; and now, it became a ritual to avoid contamination during the COVID-19 pandemic.

Soap works by dissolving the lipid membranes of microbes, then making them inactive. It has been demonstrated that water containing 1.00% powdered is useful in removing viruses and deactivates their envelope, including coronavirus .

The soap must be obtained from a liquid dispenser; the bar form is not recommended since it may contain germs. However, other studies have shown that the risk of transmitting microorganisms by washing hands with previously used bar soap is negligible (1).

ALCOHOL-BASED HAND RINSES (ABHRS)

According to WHO, the (ABHR) preparation must contain (2):

 

  • Alcohol (Ethanol, propanol): active component in the formulation which has an antimicrobial activity capable of denaturing and coagulating proteins.

  • An antibacterial agent (hydrogen peroxide (H2O2), in low concentration, used only for the inactivation of bacterial spores potentially present in the bulk product and the recipients.

  • Glycerol or other emollients that help prevent drying of the skin.

  • Distilled or boiled and cooled water.

  • The addition of other ingredients or perfumes is not recommended.

 

A recent study has confirmed the effectiveness of these WHO-recommended formulations on Sars-CoV-2 (3).

Three formats of the ABHR are recognized (gel, liquid, or foam); some studies have tried to compare their effectiveness and their virucidal action. It has been suggested that, for the adequate dose, the liquid form is much more acceptable since it is faster to dry and gives a less sticky feeling. The gel seemed to be more moisturizing. The foam format combined the two proprieties (4).

There is no precise volume of application; it varies between 1.5 and 3ml, which is equivalent to one pump from the foam bottle. Nevertheless, the quantity that is recommended by The World Health Organization is one that can cover all surfaces of the hand (2).

Summer season begins, and some dermatologists reported that the sun exposure after the application of(ABHRs) could cause burns or irritation. Still, the components of (ABHRs) are not photo-sensitizing; a study (5) realized to compare the local tolerance of alcohols commonly used an alcohol-based hand rubs for hand hygiene (ethanol, propanol) have confirmed this fact.

Hand washing after ABHRs application is not recommended, water is capable of removing superficial sebum layer as well as eliminating the emollients associated with ABHRs for hydration.

Consent

The examination of the patient was conducted according to the principles of the Declaration of Helsinki.
