Hospital-acquired infections (HAIs) refer to the infections that are acquired by patients during their stay in hospitals. These infections are caused by the transmission of pathogens, such as bacteria, viruses, fungi, and parasites, from one patient to another, or from a healthcare worker to a patient. Lack of proper sanitation in hospitals, poor infrastructure, and lack of awareness among healthcare workers are some of the common causes that are boosting the number of HAI cases. In addition, lack of training and poor infection control practices in hospitals also lead to the spreading of HAIs. Some other factors influencing the spread of HAIs include age and nutritional status. Aged people and people suffering from malnutrition have decreased levels of immunity and thus are more prone to acquire HAIs. HAIs are caused by the direct or indirect transmission of microbes. Globally, factors such as increasing government initiatives for controlling HAIs and rising prevalence of HAIs cases have helped in the growth of HAIs market.
