Infectious diseases are prevalent and have become almost inevitable due to their transmission by bacteria or viruses. The most alarming aspect of these diseases is their ability to spread from one person or object to another. They can cause significant discomfort and disrupt an individual’s health and daily activities. Recently, there has been a notable increase in certain infectious diseases, including diphtheria, Lassa fever, and cholera, which have resulted in reported cases and fatalities. According to the Nigeria Centre for Disease Control and Prevention (NCDC), as of January 24, there were 123 confirmed cases of diphtheria in Kano, Lagos, Yobe, and Osun states, leading to 38 deaths. Additionally, the NCDC reported 105 cases of Lassa fever with seven associated deaths this year. However, individuals can protect themselves from these diseases by practicing proper hygiene and taking precautionary measures.
Prof. Adesegun Fatusi, a public health and community medicine expert, emphasized that infectious diseases can easily be transmitted from one person to another, highlighting the importance of adhering to preventive measures. Although the modes of transmission may vary among different infectious diseases, he noted that preventive steps remain the most effective way to combat them. Chinyere Ukaga, an infectious disease expert and professor of public health parasitology at Imo State University, Owerri, also pointed out that while infectious diseases are widespread, they can often be prevented through simple hygiene practices.
To protect oneself from infectious diseases, maintaining proper hygiene is crucial. Ukaga stated that many diseases can be prevented by practicing good personal hygiene. This includes maintaining a clean environment, washing hands frequently, bathing regularly, drinking clean water, handling and preparing food safely, and cleaning commonly used surfaces and objects. Such simple actions can significantly reduce the risk of disease transmission. Fatusi added that proper hygiene practices, such as washing hands and disposing of waste appropriately, are essential in preventing diseases linked to contaminated food and water. He also recommended covering one’s mouth while coughing to help curb the spread of infections.
Boosting immunity is another effective strategy for preventing certain diseases. This can be achieved through vaccination and consuming a healthy diet rich in antioxidants. Fatusi noted that immunization is particularly important for infections with available vaccines, such as diphtheria, which is currently spreading rapidly. Vaccination strengthens the immune system, providing better protection against infections.
Avoiding overcrowded areas is also advisable, as such environments facilitate the transmission of infectious diseases. Fatusi cautioned individuals to steer clear of crowded places whenever possible and to maintain distance while observing other necessary precautions. Additionally, the use of facemasks should not be limited to the COVID-19 pandemic; it is an effective measure for preventing various other diseases. Ukaga emphasized the importance of wearing facemasks alongside handwashing and sanitizing, noting that this practice has significant preventive benefits.
It is crucial to avoid contact with infected individuals and objects, as infectious diseases can be transmitted in this manner. Fatusi stressed the importance of steering clear of known infected persons and objects, as well as refraining from visiting public places when feeling unwell. Understanding the specific disease and its transmission mechanism is vital for effective prevention. For instance, cholera is transmitted through contaminated food and water, necessitating the consumption of clean water and properly cooked food. In contrast, airborne diseases like tuberculosis require different preventive approaches, such as avoiding crowded spaces and wearing facemasks in public.
Increasing awareness about infectious diseases is essential for self-protection. Ukaga noted that if individuals understand how Lassa fever can be contracted from food or water contaminated by rat feces or urine, they will be more vigilant about food safety. Fatusi added that promoting preventive and protective behaviors is crucial, particularly concerning sexually transmitted diseases, where practicing safe sex can help prevent infections like HIV.
