ABSTRACT
To investigate the spread of human immunodeficiency virus (HIV) and other sexually transmitted viruses, two serosurveys (the first in 1999 among 56 adults and the second in 2001 among 351 adults) were conducted in remote villages of the southwestern part of Papua New Guinea. Only one individual was positive for antibodies to HIV. In 2001, the seroprevalence of human herpes virus 8 (HHV-8) was 32.2%, and the seroprevalence of herpes simplex virus type 2 (HSV-2) was 27.4%. Both prevalence rates increased with age, and were lower in the villages near the Bensbach River. The seropositivity of HSV-2 was independently correlated with HHV-8 infection. Our data show that the inhabitants of the southwestern region of Papua New Guinea currently experience an extremely low circulation of HIV. However, the high prevalence of infectious agents that can be sexually transmitted, such as HSV-2 and to a lesser extent HHV-8, indicates the presence of behavioral patterns that may facilitate the spread of HIV in this area of currently low endemicity.

We studied residents of remote villages and the capital (Port Moresby) of Papua New Guinea to determine the distribution of human herpesvirus-8 (HHV-8) infection. Our data suggest that HHV-8 has been endemic on the island for a long time and that the epidemiologic pattern of HHV-8 is more similar to that of herpes simplex virus-2 than hepatitis C virus.

Human trichinellosis and teniasis (Taenia solium) are meat-borne helminthic infections with a wide distribution throughout the world. However, there is little information on the prevalence of these infections in Papua New Guinea. In 1999, serum samples were collected from 97 people in 6 villages in the remote Bensbach area of Papua New Guinea. Enzyme-linked immunosorbent assay and Western blot analyses were used to detect anti-Trichinella immunoglobulin (Ig) G and anti-cysticercus IgG in this population. The prevalence of Trichinella antibodies among inhabitants of the Bensbach area was 28.9% (28 of 97; 67.8% in men), suggesting a high consumption of poorly cooked meat. The higher prevalence of infection for Trichinella in men compared with women may be explained by the inclination of men to eat undercooked pork while hunting. All serum samples were negative for cysticercus antibodies. This is to our knowledge the first serosurvey showing anti-Trichinella antibodies in a human population living in Papua New Guinea (Australian region).

Papua New Guinea (PNG) is at a crossroads in child health care. We know how to treat or prevent most of the diseases causing child and maternal mortality, but we are failing to deliver the services to where most of the people are dying. There is much to be learnt from early achievements in the development of health services in PNG. Between the 1950s and 1970s the infant mortality rate fell from 250-500 per 1000 livebirths to 77-100 per 1000 livebirths. This occurred predominantly because of an emphasis on public health programs and cost-effective standard treatment. Now the public health services have deteriorated, vaccine coverage is poor and health workers are not fully using the standard treatment resources available to them. The greatest academic and practical challenges facing medicine in PNG are to implement effective and consistent delivery of vaccines, and nutritional, basic curative and maternal care to remote or impoverished communities. The other unmet prerequisites for improvement in health status are that communities participate in and take some responsibility for their health care needs. There are now unprecedented opportunities for collaboration with international partners, churches, non-government organizations and community groups to achieve these goals. Specific key strategies in child health include the more widespread utilization of the 10-Step Checklist, adoption of some of the World Health Organization Integrated Management of Childhood Illness strategies, increased output of child health nursing training, improving vaccine delivery and cold-chain services, and new immunization strategies for acute respiratory infections. The National Health Plan 2001-2010, launched in August 2000, emphasizes the vital importance of public health; the need for greater access to quality health services; improving clinical skills among health workers at all levels; and cooperation between all interested parties. By 2010 the National Health Plan must be judged not on how good the plan seemed on paper, but on whether there was a measurable reduction in maternal and child mortality over the first decade of this century.

A prospective study of 40 children with epilepsy was carried out between June 1990 and August 1991 at Port Moresby General Hospital. Half of the children had yet to start school. Significant features in their past medical histories were acute meningitis (38%), tuberculous meningitis (10%), febrile convulsions (10%) and head trauma (5%). Most cases had grand mal epilepsy (80%). The majority of the children with epilepsy (90%) were treated with a single drug, which was usually phenobarbitone. 22% had received more than one drug, but not simultaneously. Significant side-effects requiring change of treatment occurred in 10%. Disturbed behaviour was reported in 55% and 22% had a poor social outcome. 45% had complete control of fits clinically. This study showed that in Port Moresby acute meningitis is a significant cause of epilepsy in young children, the majority of whom present with grand mal epilepsy, which is usually controlled by phenobarbitone, a readily available and cheap drug and still a useful anticonvulsant in the developing world.
