Description

Neonatal sepsis causes a significant burden of morbidity and mortality, including infections of the bloodstream, urine, cerebrospinal cord, peritoneum, and lungs, as well as infections resulting from burns and wounds, or other normally sterile sites. It is associated with cytokine and bio mediator-induced respiratory disorders, hemodynamic and metabolic processes. Newborns in the NICU have many specific risk factors for bacterial and fungal sepsis. Loss of intestinal symbiotic bacteria such as bifid bacteria and Lactobacillus can occur with prolonged antibiotic treatment, delayed enteral nutrition, or incubator feeding, with growth of pathogenic microbial flora and abnormal intestinal tract. It leads to colony formation. Prompt diagnosis and effective treatment do not protect newborns with sepsis from the risk of late neurodevelopmental disorders in the survivors.

The most common site of infection is the bloodstream, followed by the respiratory tract and gastrointestinal tract. Strains of S. marcescens involved in epidemic events are often shown to be multidrug resistant. In fact, this species exhibits inherent resistance to multiple classes of antibiotics. In many cases, it is not possible to identify a particular source of infection. However, contaminated hands of health care workers are considered to be the primary transmission route. In the neonatal intensive care unit, colonized or infected newborns, especially in the respiratory system as well as in the gastrointestinal tract. It is the main source of marcescens. Early detection of colonization or infected patients and timely implementation of infection control measures, especially consistent hand hygiene and contact protection, are essential to control the spread of the infection.

Fever in infants can be caused by a bacterial infection. These include blood infections (bacteraemia), urinary tract infections, and brain or cerebrospinal fluid infections (bacterial meningitis). Determining if an infant is infected with a bacterium is currently associated with considerable cost and risk. Health providers need to collect blood, urine, and CSF samples. This may require invasive procedures such as lumbar puncture (spine puncture). The sample is then cultured to grow and identify the bacteria. While waiting for test results, the child may be hospitalized or given antibiotics, which may prove unnecessary. When bacteria infect a person, the immune system turns on certain genes and creates a unique “bio signature.” In adults and older children, diagnostic tests can distinguish between bacterial and viral infections by analysing the response of the immune system. However, it was unclear whether this approach would work in infants as the immature immune system may not elicit a measurable response.

Viral infections in newborns result in significant morbidity and mortality each year. Foetus and newborns are particularly vulnerable to viral infections. The range of expression can range from no clinical disease to catastrophic prenatal, intranasal, or postnatal catastrophic diseases and infections. Care management is determined by the specific viral infection, the severity of the disease, and the unique condition of the newborn and his family. Promising new therapies that have the potential to reduce the severity of viral diseases are imminent. So far, the most important directions in the treatment of neonatal viral diseases have been the prevention of infectious diseases and the supportive care of newborns with acute diseases. Viral infections are caused by a virus, which is a very small bacterium. There are thousands of different viruses that can cause a variety of infections and health conditions.

The virus attacks healthy cells in your body. They replicate and proliferate using healthy, living host cells. As a result, infected host cells cannot perform their normal functions. Some viruses kill the host cell, while others change the way the host cell works. The virus then migrates to other cells and infects or destroys them in the same way.

A healthy immune system can fight off most viral infections, but some viruses can cause serious problems. The virus can affect certain organs and can affect various body systems.

Candida infections are a major cause of morbidity and mortality in neonatal intensive care units. Mortality following Candida bloodstream infections is as high as 40%, and neurodevelopmental impairment is common among survivors. Because invasive fungal infections are common and extremely difficult to diagnose, empirical treatment with antifungal therapy should be considered in high risk, low birth weight infants who fail to quickly respond to empirical antibacterial treatment. Risk factors to consider when deciding to administer empirical antifungal therapy include: prior exposure to third generation cephalosporin, extreme prematurity, and presence of central venous catheters. Neonatal infections cause a massive burden of mortality and morbidity, most of which occur in low income and middle income countries in settings characterized by high risk household practices, poor care seeking and access to quality care, and weak health systems. Infectious disease monitoring is inadequate, but limited data suggest increased antibiotic resistance. However, many prophylactic and therapeutic interventions are available and, when implemented effectively on a large scale, can prevent the death of most newborns worldwide from serious infections. The development of newly adapted tools and technologies promises to increase the availability and impact of interventions to prevent death from infection. However, implementation challenges continue to limit the scope of intervention. New efforts are needed to provide evidence-based interventions at the community level and in the health environment that are integrated into maternal and child health programs.
