Strategies for Home Disinfection Against Coronavirus
Amid the complex situation of the novel coronavirus (nCoV) respiratory disease outbreak, health experts have outlined cleaning strategies for homes and environments to mitigate the spread of the virus.
Dr. Pham Quang Thai, Deputy Head of Infectious Disease Control at the National Institute of Hygiene and Epidemiology, suggests that high temperatures above 25 degrees Celsius can rapidly destroy nCoV, thereby lowering the risk of infection. However, despite the virus's reduced viability on surfaces in hot conditions, direct and droplet transmission from infected individuals poses a continued risk, emphasizing the need for vigilance regardless of warm weather.
Furthermore, Dr. Pham Quang Thai explains that nCoV has a weak survival rate outside of the human body and can be effectively neutralized by common disinfectants such as 70% alcohol, 0.5% Chloramine B, and soap. Thus, regular home cleaning is vital to protect oneself and family from not only nCoV but various pathogens. Families are encouraged to routinely disinfect their living spaces to prevent nCoV infection.
Dr. Truong Huu Khanh, head of Social Work at Children's Hospital 1 in Ho Chi Minh City, emphasizes the critical importance of maintaining a clean environment and home as a defense against nCoV, similar to precautions taken against flu and hand, foot, and mouth disease viruses. Disinfectants like Chloramine B and Javel water are commonly employed in these efforts.
To date, there are no specific studies on the survival of nCoV in various environments. Our understanding comes from research on similar coronaviruses like SARS and MERS-CoV. It's noted that the virus becomes less viable in temperatures above 25 degrees Celsius and humidity levels over 50%, and well-ventilated areas can significantly reduce viral concentration and spread.
Dr. Truong Huu Khanh also notes that while coronavirus may weaken in conditions of high heat and humidity, this does not eliminate the need for preventive measures in such climates. Given the virus's tendency to cause cold-like symptoms in cooler weather, the hope is that the end of winter and the onset of warmer temperatures in temperate regions will lead to a decrease in disease transmission.
