Cardiomyopathy – diseases of cardiac muscle
Hypertensive heart disease – diseases of the heart secondary to high blood pressure or hypertension
Heart failure - a clinical syndrome caused by the inability of the heart to supply sufficient blood to the tissues to meet their metabolic requirements
Pulmonary heart disease – a failure at the right side of the heart with respiratory system involvement
Cardiac dysrhythmias – abnormalities of heart rhythm
Inflammatory heart disease
Endocarditis – inflammation of the inner layer of the heart, the endocardium. The structures most commonly involved are the heart valves. Inflammatory cardiomegaly
Myocarditis – inflammation of the myocardium, the muscular part of the heart, caused most often by viral infection and less often by bacterial infections, certain medications, toxins, and autoimmune disorders. It is characterized in part by infiltration of the heart by lymphocyte and monocyte types of white blood cells. Eosinophilic myocarditis - inflammation of the myocardium caused by pathologically activated eosinophilic white blood cells. This disorder differs from myocarditis in its causes and treatments. Valvular heart disease
Congenital heart disease – heart structure malformations existing at birth
Rheumatic heart disease – heart muscles and valves damage due to rheumatic fever caused by  Streptococcus pyogenes a group A streptococcal infection.

52% of a total of 526 tested households infected
Could not identify species, but previous studies in North Vietnam reported N. americanus in more than 95% of hookworm larvaeMinas Gerais, Brazil (Fleming et al. 2006)
63% infection rate of predominantly N. americanusKwaZulu-Natal, South Africa (Mabaso et al. 2004)
Inland areas had a prevalence rate of 9% of N. americanus
Coastal plain areas had a prevalence rate of 63% of N. americanusLowndes County, Alabama, United States 
35% infection rate of predominantly N. americanusThere have also been technological developments that may facilitate more accurate mapping of hookworm prevalence. Some researchers have begun to use geographical information systems (GIS) and remote sensing (RS) to examine helminth ecology and epidemiology. Brooker et al. utilized this technology to create helminth distribution maps of sub-Saharan Africa. By relating satellite derived environmental data with prevalence data from school-based surveys, they were able to create detailed prevalence maps. The study focused on a wide range of helminths, but interesting conclusions about hookworm specifically were found. As compared to other helminths, hookworm is able to survive in much hotter conditions and was highly prevalent throughout the upper end of the thermal range.Improved molecular diagnostic tools are another technological advancement that could help improve existing prevalence statistics. Recent research has focused on the development of a DNA-based tool that can be used for diagnosis of infection, specific identification of hookworm, and analysis of genetic variability in hookworm populations. Again this can serve as a major tool for different public health measures against hookworm infection.
