The World Health Organization (WHO) convened a Scientific Group to adapt its program in virus diseases to recent progress in virology. The program consists of (a) general activities, such as reference services and the supplying of reagents by the WHO Collaborating Centres and (b) specific activities to solve problems-including the promotion of necessary research-caused by certain diseases of public health importance. The Group reviewed problems caused by influenza and other respiratory viruses, enteroviruses, gastroenteritis viruses (for which types A and B have been proposed as a convenient nomenclature), viral hepatitis, viruses in water and sewage, arboviruses, arenaviruses and Marburg virus, measles and rubella vaccination, smallpox, rabies, chronic infections, herpesviruses, oncogenic viruses, congenital infections, nosocomial infections, chlamydial and rickettsial infections, and mycoplasma infections.

Bivalve mollusks (oysters, clans, and mussels) filter large quantities of water unselectively and thereby may concentrate a variety of aquatic contaminants pathogenic for man within edible shellfish viscera. The recognized bacterial disease associated with ingestion of contaminated bivalves include typhoid fever (not presently a public health problem), Vibrio parahemolyticus gastroenteritis, and Vibrio chloerae infection. The major known shellfish-associated viral diseases are viral hepatitis and possibly viral gastroenteritis. The ingestion of bivalves that have fed on the toxic species of dinoflagellates that produce red tides may be responsible for an uncommon and very rarely fatal illness, paralytic shellfish poisoning. Outbreaks of airborne respiratory irritation in populations exposed to red tides may be the most common public health problem associated with red tides. The health hazards resulting from industrial, agricultural, and oil pollution of bivalves in coastal waters and the hazard from improper handling of bacterially contaminated mollusks remain to be defined.

Using computerized in-patients' discharge records, a descriptive analysis was carried out of all medical admission in 1987 in a general hospital. The survey found that there were a total of 4053 admissions in 1987. A wide range of medical disorders were seen reflecting the lack of subspecialization. Cardiovascular disorders topped accounting for 25.6% of all admissions, followed by gastrointestinal and hepatobiliary disorders 12.8% and respiratory disorders 10.7%. The commonest specific medical disorders seen were hypertension 13.8%, diabetes mellitus 10.2%, ischaemic heart disease 7% and asthma 4.5%. The age, sex, ethnic and geographical distributions of the common medical disorders seen appear to conform to two broad pattern; hypertension, diabetes, ischaemic heart disease and cerebrovascular disease affected the older patients, had even ethic distribution and predominantly urban. Malaria, non-specific fever, viral hepatitis and acute gastroenteritis affected the younger patients, predominantly rural and Malay. Information from such surveys may be useful for planning and organization of medical services.

Recent studies have provided a greater understanding of the movement of viruses in the environment by their attachment to solids. These studies have focused on solids-associated viruses present in wastewater discharged into the ocean and on viruses in sludge and wastewater that may be retained in soil following their land disposal. Such ocean or land disposal of wastewater and sludge may result in a discharge of one or more of 120 human enteric virus pathogens including those causing poliomyelitis, viral hepatitis A and acute gastroenteritis.Solids-associated viruses in effluents discharged into coastal waters accumulate in bottom sediments, which may contain 10 to 10 000 more virus per unit volume than the overlying seawater. Solids-associated viruses resuspended by water turbulence may be transported from polluted to distant non-polluted recreational or shellfish-growing water. Transmission of viruses causing hepatitis or gastroenteritis may result from contact by bathers or swimmers with these viruses in recreational waters, or from ingestion of raw or improperly cooked shellfish in which the solids-associated virus had been bioaccumulated.The land disposal of sludge and wastewater has a potential of causing infections in farm workers, contamination of crops, pollution of raw potable water sources or infiltration of ground water. Viruses retained on soils can be released by rain water and may contaminate ground water through lateral and vertical movements.

The clinical features and laboratory findings of 78 cases of methyldopa fever are reported. This drug reaction masqueraded as a variety of acute infectious diseases including septicaemia, meningitis, hepatitis and gastroenteritis, occurred within five weeks of starting the drug and appeared to be unrelated to its dosage. Eosinophilia and skin rashes were conspicuous by their absence. In the majority of patients, symptoms were relieved within 48 hours of the withdrawal of the drug. Sixty-one per cent of patients had biochemical evidence of liver damage but jaundice was uncommon. This pattern of mild hepatotoxicity in patients with early febrile reactions to methyldopa contrasts with the later more serious viral hepatitis-like illness due to the drug.

One hundred and twenty patients with a mean age of 38 years (range 12-85 years; M 91, F 37) were studied over a period of 5 years in a teaching hospital in Dhaka. Sixty-two patients presented with probable anuria with 1-4 days' duration, 63 patients presented with oliguria, and 3 were nonoliguric. The causes of acute renal failure were medical (94), surgical (22), obstetrical (13). Of the medical cases, the causes were gastroenteritis in 42 cases, gastroenteritis with CNS involvement in 11 cases, rapidly progressive glomerulonephritis in 10 cases, acute viral hepatitis in 8 cases, and septicemia in 8 cases. Of 22 surgical cases, postoperative acute renal failure was the cause in 9, road traffic accident in 6, and renal calculus disease in 7. There were 13 cases in the obstetrics group, of whom 9 were due to abortion, 2 were due to preeclampsia, and the other 2 were postoperative. The mean blood urea of all cases was 35 mmol/L and serum creatinine was 988 mumol/L. Dialysis was required in 105 cases; of these, 72 were medical cases, 21 were surgical cases, and 12 were obstetric cases. The overall survival rate was 75%. The improved survival is probably due to timely referral and prompt medical management.

Many diseases are transmitted to man by consumption of contaminated food and drinking water. Orally transmitted diseases are among the main risks for travelers in developing and tropical countries. A variety of clinical manifestations can be observed but the diarrhea is the most common. In many cases bacterial gastroenteritis, typho-paratyphoidal fever, brucellosis, viral hepatitis, and various parasitic diseases can develop after various periods of incubation following consumption of contaminated food or drink with no initial reaction. Vaccination can afford protection against only few diseases. Prevention by applying good hygiene and common sense is the best method. By following the standard list of food precautions, travelers can minimize the main risks. Drug prophylaxis is recommended only under special circumstances. Travel medicine providers must have up-to-date information and possess the persuasive powers necessary to convince travelers to apply recommendations despite the major inconveniences.

Oman is generally hot and dry, but the Salalah region in southern Dhofar province is relatively cool and rainy during the summer monsoon, and has a distinctive pattern of infection. Important, notifiable infections in Oman include tuberculosis, brucellosis (endemic in Dhofar), acute gastroenteritis, and viral hepatitis: 4.9% of the adults are seropositive for hepatitis B surface antigen and approximately 1.2% for hepatitis C virus. Infection with human immunodeficiency virus is uncommon, and leprosy, rabies, and Crimean-Congo hemorrhagic fever are rare. Between 1990 and 1998, the incidence of malaria, (>70% due to Plasmodium falciparum) decreased from 32,700 to 882 cases. Cutaneous and visceral leishmaniasis (caused by Leishmania tropica and L. infantum, respectively) and Bancroftian filariasis occur sporadically. Intestinal parasitism ranges from 17% to 42% in different populations. A solitary focus of schistosomiasis mansoni in Dhofar has been eradicated. There are major programs for the elimination of tuberculosis, leprosy, and malaria, and to control brucellosis, leishmaniasis, sexually transmitted diseases, trachoma, acute respiratory infection in children, and diarrheal diseases. The Expanded Program on Immunization was introduced in 1981: diphtheria, neonatal tetanus, and probably poliomyelitis have been eliminated.
