Incidence and Prevalence
Global Estimates of Infection Incidence and Prevalence
Viral Infections
Hepatitis B virus (HBV) infection has shown declining prevalence in Asian and Pacific nations with universal immunization programs, with twenty-seven of 34 Pacific and East/Southeast Asian nations achieving >70% vaccination coverage in infants.
Hepatitis C virus (HCV) has a worldwide prevalence estimated at 3.1% or approximately 170-210 million infected people globally, with 3-4 million newly infected annually. The Latin America region has one of the lowest prevalence rates at around 1.23%. The highest HCV prevalence occurs in Egypt, sub-Saharan Africa, Amazon basin and Mongolia.
Herpes simplex virus (HSV) infections are highly prevalent globally. HSV type 1 affects an estimated 3752.0 million people, representing a global prevalence of 66.6% in 0-49-year-olds. HSV type 2 infects approximately 491.5 million people, equivalent to 13.2% of the world's population aged 15-49 years, with highest prevalence among women and in the WHO African Region.
Polyomaviruses (BKPyV and JCPyV) are widely distributed globally with a frequency of 80-90% across different populations. The Korean population has the highest BKPyV frequency (66.7%), while JCPyV is most prevalent in Taiwan (88%).
Bacterial Infections
Bacterial infections contribute significantly to the more than 17 million deaths from infectious diseases worldwide each year. In retail chicken meat environments, S. aureus showed the highest pooled prevalence (56%), followed by E. coli (50%), C. perfringens (35%), and K. pneumoniae (21%).
P. aeruginosa has an overall prevalence of 22.9% in Asia and Africa over the past 5 years. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) P. aeruginosa strains were found at rates of 46.0% and 19.6% respectively.
Sexually transmitted bacterial diseases show five to 10 times higher incidence rates in ethnic minorities compared to the general population. Among female commercial sex workers in Mexico City, prevalences included Treponema pallidum (6.4%), Neisseria gonorrhoeae (3.7%), and Chlamydia trachomatis (11.1%).
Fungal Infections
The global incidence of pulmonary fungal infections in 2021 was estimated at 5.62 million cases with 45,542 deaths. The age-standardized mortality rate was 0.56 per 100,000, with projections suggesting over 87,000 deaths by 2044.
In the Netherlands, the total burden of serious fungal infections affects approximately 1.5% of the population annually, including 3,185 patients with serious invasive fungal infections.
Parasitic Infections
Microsporidia infection showed an overall prevalence of 29.2% among immunocompromised patients in Malaysia, with end-stage renal failure patients having the highest infection rate (32.1%).
A Spanish prison study found that 15.7% of inmates were infected with intestinal parasites, with Blastocystis sp. being the predominant parasite (44.6% of infections).
For giardiasis and cryptosporidiosis in Spain, children were infected by Giardia in significantly higher proportions, particularly in the 5-14 years age group, while Cryptosporidium infection rates were similar between boys and girls (1.4% vs. 1.3%) in children aged 2-4 years.
In AIDS patients, opportunistic infections were found in approximately one third of cases, with Cryptococcus, cytomegalovirus and toxoplasma being the three most common infections.
Key Unmet Needs / Populations for Infections
Fungal Infections
- Invasive fungal infections have become considerably more frequent in the last 50 years, with high mortality rates creating an unmet need for innovative strategies
- No fungal vaccine has been approved for humans as of 2024
- African settings face challenges due to poorly funded healthcare systems
- Low performance diagnostics and limited therapeutics contribute to unacceptably high death rates
Displaced Populations
- Over 108 million forcibly displaced people globally as of 2022
- Forced migration increases risk of infectious disease transmission
- Refugees were the most common population investigated (75%) in research
- Limited access to hygiene/sanitation and crowding are key predictors of infection
Key Populations
- Men who have sex with men and transgender individuals face criminalization and discrimination
- These populations have limited access to antiretroviral therapy despite higher rates of HIV/AIDS
- People with chronic illnesses such as HIV, hypertension, and Diabetes Mellitus are priority populations for COVID-19 vaccination
- Children, the elderly, and individuals with comorbidities are prone to coronavirus-related hospitalization
Antibiotic Resistance
- Refugee camps show extensive antibiotic consumption in loosely regulated contexts
- High consumption of antibiotics increases antimicrobial resistance
- 93.7% of E. coli isolates in one study were classified as multidrug-resistant
- ESKAPE pathogens represent a major global health threat
Antimicrobial Stewardship Challenges
- Only 25.8% of surveyed African countries have developed a national antimicrobial stewardship policy
- 74.2% of African countries have no budget for antimicrobial stewardship activities
- Access to diagnostics and antibiotic susceptibility testing remains a barrier in LMICs
- Implementation is limited by insufficient funding and shortage of infectious disease physicians
Viral Infection Gaps
- No FDA-approved vaccines or therapeutics for hantaviruses
- Timeline to vaccine development can be extensive, leading to lapse in controlling viral spread
- We are inadequately prepared for unknown emerging infectious diseases
- Many antigens difficult to produce in large quantities, such as the spike protein antigen of COVID-19, have not yet been developed
Risk Factors and Comorbidities
Top 3 Risk Factors and Comorbidities for Infections
1. Medical Device Usage
Medical devices represent a major risk factor for infections, with three types of infection (pneumonia, urinary tract infection and primary bloodstream infection) accounting for more than 60% of all nosocomial infections. These infections are directly associated with the use of medical devices. In burn patients, the main sources of blood stream infections were the burn wounds, followed by infected catheters. Extracorporeal membrane oxygenation (ECMO) is also associated with healthcare-associated infections, with prolonged ECMO duration being an independent risk factor. Indwelling medical devices, particularly central venous lines (66% of blood stream infections) and urinary catheters (71.4% of Providencia bacteremia cases) significantly increase infection risk.
2. Hospitalization and Healthcare Exposure
Between 5 and 10% of patients admitted to acute care hospitals acquire one or more infections, and the risks of hospital-acquired infections have steadily increased during recent decades. Hospital-acquired infections are significantly associated with higher rates of dementia (hazard ratio 1.70). Factors that increase risk in healthcare settings include inadequate hand hygiene by healthcare workers, inappropriate antibiotic use, increasing prevalence of multidrug-resistant organisms, suboptimal disinfection of hospital rooms and equipment, and invasive procedures that breach normal host defenses. Patients in ICUs account for 45% of all hospital-acquired pneumonias and bloodstream infections, despite critical care units comprising only 5% to 10% of all hospital beds. Length of hospital stay is also significantly associated with infections in pediatric patients (p = 0.000).
3. Underlying Health Conditions and Comorbidities
Several underlying conditions significantly increase infection risk. Age is a critical factor, with infections most common in individuals aged 51-60 years in one study, and elderly patients identified as high-risk due to immunosenescence. Gender differences exist, with men more affected (60.78%) than female patients (39.22%) in community-acquired infections. Poor dental hygiene is associated with infections, particularly with Redondoviridae family (ReDoVs) presence. Specific comorbidities that increase risk include liver diseases, cardiac diseases, gastrointestinal diseases, and diabetes mellitus. In patients with systemic lupus erythematosus (SLE), risk factors associated with in-hospital mortality include nosocomial infections (OR 5.0), lymphopenia (OR 2.1), anemia (OR 2.9), and thrombocytopenia (OR 3.3). Hyperglycemia in diabetic patients affects host immune responses, leading to increased severity of pneumococcal infections through metabolic dysregulation that activates stress pathways and modifies nucleotide sugar availability.
