Prevention of COVID-19

COVID-19 อันตรายถึงหัวใจ

To control endemic spread of COVID-19, public awareness in reducing disease transmission must be raised. Recommendations made by WHO and health authorities include:

  • Frequent washing of hands with soap and water which takes at least 20 seconds per time.  Alcohol-based hand rub  can be also used. Alcohol-based hand rub or hand sanitizer with at least 60% – 70% alcohol is considerably equal to soap and water. Washing hands with soap and water or using alcohol-based hand rub kills viruses that may be on the hands.

  • Wearing medical/surgical masks properly by placing mask carefully to entirely cover mouth and nose. Masks  must be tied securely to minimize any gaps between the nose and the mask. While in use, avoid touching the mask. To remove the mask, the lace should be removed from behind. After removal or whenever inadvertently touching a used mask, hands must be cleaned by using an alcohol-based hand rub or soap and water if visibly soiled. Do not re-use single-use masks. Discard single-use masks after each use and dispose of them immediately upon removal. The inner side of used masks must be folded and thrown away into infectious waste.  By limiting the volume and travel distance of expiratory droplets dispersed when sneezing, coughing or talking, masks can serve a public health benefit in reducing transmission by those unknowingly infected.

  • Healthy people are accepted to wear medical-grade masks while suspected or infected patients need to wear surgical face masks and N95 respirators in order to limit disease transmission.

  • Touching face, eyes, nose, mouth must be avoided. Hands touch many surfaces and can accidentally pick up viruses. Once contaminated, hands can transfer the virus to the eyes, nose or mouth. From there, the virus can enter the body and cause disease.

  • Good respiratory hygiene is essentially vital. During sneezing or coughing, instead of using hands, it is highly recommended to cover the mouth and nose with bent elbow or tissue, then used tissue must be disposed immediately in the contaminated garbage. If hands are used to cover the mouth and nose, hand wash is always needed.

  • Since coronavirus droplets stay suspended in the air for a short time and it can also stay viable and contagious on a metal, glass or plastic surface for up to several days, touching surfaces e.g. a doorknob, tabletop, staircase railing, lift buttons and IT equipment must be frequently cleaned with alcohol or soap and water, depending on material types.

  • Visiting congested places such as cinemas, shopping malls, food courts, bus stations, train stations, airports should be avoided. If necessary, exposure time must be as short as possible. Wearing masks and frequent hand wash are crucial.

  • Viruses can be excreted via stool, covering the toilet lid while flushing is definitely essential in order to reduce the transmission of viruses in the air. Toilet disinfectants might be helpful and can be also used.

  • Even though science is racing to develop vaccines to blunt the outbreak’s impact. Currently, there is no specific vaccine to prevent infections against COVID-19 disease. Although symptoms caused by COVID-19 are fairly similar to those induced by influenza viruses, influenza vaccines or flu shots are vaccines that only protect against infection caused by influenza viruses, NOT coronaviruses. Therefore being vaccinated with influenza vaccines does not help minimizing the risks of novel coronavirus infections.
