In Ethiopia during 1960-1962, more than 100,000 people in the Omo and Didessa river valleys acquired yellow fever and 30,000 died. There have been no yellow fever cases since 1966. Some other aboviruses that arise sporadically are Jos virus, dengue fever, Crimean-Congo hemorrhagic fever, and group A arboviruses. By age 15, all people in surveyed regions were positive for
hepatitis A
virus. Prevalence of hepatitis B virus increases with age ( 75% of adults in urban areas and many rural areas). The frequency of carriers of hepatitis Bs antigen is greatest in areas where people practice ceremonial tattooing. During 1988-1989, 93% of jaundiced patients in a military camp in Ethiopia had antibodies to hepatitis E virus as a result of a waterborne outbreak. Other hepatitis viruses in Ethiopia are delta and C viruses. All 3 serotypes of poliovirus exist, especially type III. 93% of 1-year-olds have already acquired immunity to it. Peak frequency of onset among paralytic cases is 2 cases. Measles epidemics are common in children. An outbreak in southwestern Ethiopia had a mortality rate of 20%. Immunity to rubella is around 85% for 14-year-olds. It increases with age. Rotavirus causes diarrhea in many children, especially among 7-12 month old infants and in June and November. Most children have been exposed to Epstein-Barr virus, which is responsible for mononucleosis and maybe for Burkitt's lymphoma. Officials do not conduct ongoing surveillance of influenza in Ethiopia. Influenza epidemics have occurred in 1957 and 1963. Rabies is endemic, with dogs being responsible for most cases. In November 1992, there were 3978 AIDS cases. 75% are less than 40 years old, with males more likely to be
HIV
infected than females. The Falashas of northwest Ethiopia have the world's second highest endemic rate of human T cell leukemia virus-1. Officials do not know the extent of viral diseases because there is no well organized national laboratory. One is needed to conduct surveillance and to evaluate the effectiveness of vaccination activities.

This prospective study was carried out with the aim of evaluating the efficacy of solvent/detergent inactivation of the hepatitis C virus (HCV) as applied to a chromatographic factor VIII concentrate. In parallel, the markers for other viruses, either lipid-enveloped (human immunodeficiency virus types 1 and 2 [
HIV
-1 and -2] and hepatitis B virus [HBV]) or non-lipid-enveloped viruses (such as B19 parvovirus and
hepatitis A
virus [HAV]) were evaluated. The study included 14 hemophilia centers, which enrolled 36 previously untreated patients (median age, 3 years; range, 1-56). The length of follow-up was 12 months, during which HCV (first- and second-generation assays and recombinant immunoblot assay),
HIV
-1 and -2, HBV, HAV (IgG and IgM), and parvovirus (IgG and IgM) antibodies, as well as alanine aminotransferase values were evaluated. Thirty-one patients were analyzable; none seroconverted for HCV, HBV, or
HIV
after exposure to a total of 165,000 IU of factor VIII (41 different lots). In one patient, alanine aminotransferase values rose to 167 mU per mL, 6 weeks after the first concentrate infusion, and this patient seroconverted for HAV 1 week later. Furthermore, 10 patients seroconverted for parvovirus during follow-up. This study suggests that the solvent/detergent method of virus inactivation is efficient in relation to lipid-enveloped blood-borne viruses but not in relation to non-lipid-enveloped viruses.

Forty-one patients with hemophilia A were studied for the prevalence of serological markers for
hepatitis A
, hepatitis B, hepatitis C (non-A and non-B hepatitis), and delta hepatitis (hepatitis D). Ten of 41 (24.4%) patients demonstrated
hepatitis A
antibody and 31 of 41 (75.6%) patients had a serologic marker for previous hepatitis B infection; four of these 31 patients (13%) also demonstrated antibody to delta agent (hepatitis D). Thirty-seven of 41 (90.2%) patients demonstrated antibody for hepatitis C. Nine of 31 (29%) patients with a hepatitis B marker (no hepatitis B vaccinees) were negative for anti-HBc but positive for anti-HBs; all of these nine patients were
HIV
antibody positive, although they had no overt immunodeficiency. Twenty-six of 41 (63.5%) patients were
HIV
antibody positive. Of
HIV
antibody positive patients, 27%, 88%, and 100% demonstrated evidence of a previous
hepatitis A
, hepatitis B, or hepatitis C, respectively. Of
HIV
antibody negative patients; 20%, 53%, and 73% of the patients demonstrated evidence of a previous
hepatitis A
, hepatitis B, or hepatitis C infections, respectively. The difference between
HIV
antibody positive and
HIV
antibody negative groups was not significant for
hepatitis A
but was significant for hepatitis B (P < 0.001) and hepatitis C (P < .001). Of the 31 patients with a hepatitis B serologic marker, all had antibody to hepatitis C. Of 10 patients, without a hepatitis B serologic marker, only 6 (60%) had antibody to hepatitis C.(ABSTRACT TRUNCATED AT 250 WORDS)

Legislation of the control of sexually transmitted diseases (STD) in the Federal Republic of Germany covers neither the complete spectrum of venereal diseases nor all population groups of high risk. We therefore investigated not only the classic STD but also some other STD, i.e. by serologic methods syphilis,
HIV infection
,
hepatitis A
, B, C, and herpes simplex genitalis, and by microbiological methods gonococci, chlamydiae, trichomonas, genital mycoplasmas, A-streptococci, B-streptococci, gram-negative enteric bacteria, anaerobic bacteria, staphylococci, listerias and yeasts. The cohorts of women living mainly monogamously and these of prostitutes were compared. They show some differences: There are remarkable differences in the prevalence of clinical symptoms, i.e. vaginal discharge, rubor, pruritus, and genital warts, between the two cohorts and depending on the season. Fluor, rubor, and pruritus were more frequently observed in mainly monogamous women than in prostitutes. Furthermore, the causative organisms of STD were isolated in different frequencies depending on the season particularly from mainly monogamous women. Furthermore, their frequencies depend on the age of the women. Gonococci, chlamydiae, trichomonas, genital mycoplasmas, B-streptococci and Staphylococcus aureus were significantly more isolated from prostitutes than from mainly monogamous women. But, on the other hand, candida and gram-negative enterobacteria are significantly more common in mainly monogamous women than in prostitutes. There are some correlations between clinical symptoms and organisms. The prevalence of syphilis,
HIV
-infection,
hepatitis A
, B, and C in the prostitutes were 7, 0.4, 3.5, 15, and 1.6%, respectively. The most intriguing observation is the decreasing incidence of causative organisms of STD in prostitutes during the three years of study. This phenomenon promises an improvement of the health standard of prostitutes by regular medical, microbiological, serological check-ups without charge.

Addiction, because of its associated psychological and physical diseases, is producing increasing expenses through social burden and influencing the epidemiological situation of the whole population via sexual or simple intimate social contacts. Outstanding infectious diseases with a high incidence in drug addicts are tuberculosis,
hepatitis A
, hepatitis B and the classical notifiable venereal diseases. Preventive measures are required, involving immunization and isolation.
HIV infection
is another increasing problem in drug addicts. The relatively long asymptomatic course in this population also raises the potential for the spread of AIDS to the general population. There is no ideal method for preventing this danger, but because the traditional abstinence paradigm has not been successful, methadone substitution is improving the medical compliance of this difficult clientele, reducing crime and prostitution and, at the same time, drug-associated risks for the general population.

There is a distinct spectrum of infectious diseases in prisons, known as desmoteric infections. We investigated the incidence of
HIV
,
hepatitis A
, B, and C in a group of 539 prisoners and compared them with the incidences of these infections in the normal population. The incidence of
HIV
was 928 out of 100,000. This figure is similar to that of the normal population. Hence,
HIV infection
does not seem to be a desmoteric disease. In contrast to AIDS the incidences of
hepatitis A
, B, and C among prisoners were 2968, 1670, and 20,000, respectively. Of course,
hepatitis A
, B, and C occur 100-200 times more often among prisoners and thus seem to be desmoteric infections. Moreover, especially hepatitis C is correlated strongly with intravenous drug abuse. About 80% of drug abusers were HCV positive and 50% of the total of HC infections are due to drug abusers.

The prevalence of
hepatitis A
, B, C, and D viruses was studied in 467 military personnel with human immunodeficiency virus type 1 (HIV-1) infection. Antibody to hepatitis C virus (anti-HCV) by first-generation ELISA was found in 136 (29%). Of sera repeatedly reactive for anti-HCV by first-generation ELISA, two-antigen recombinant immunoblot assay (RIBA) was positive in 41 (32%) and four-antigen RIBA was positive in 55 (41%). Four-antigen RIBA was positive in 33 (30%) of the 109 with an OD on ELISA of < or = 2.0 compared with 22 (81%) of the 27 with an OD > 2.0 (P < .001). Anti-HCV detected by four-antigen RIBA was associated with increasing age, black or Hispanic race, and antibody to hepatitis B core antigen. When patients with hepatitis B surface antigen were excluded, elevated alanine aminotransferase was found in 5 (8%) of 63 with a negative RIBA and 13 (28%) of 47 with a positive RIBA (P = .006). While RIBA was negative in more than half of those with anti-HCV by ELISA, 55 (12%) of these
HIV
-1 infected personnel had anti-HCV detected by RIBA, which was associated with a strong reaction by ELISA, elevated liver enzymes, coinfection with hepatitis B, minority race, and older age.

Two atypical serological markers of hepatitis B virus (HBV) infection were detected in 19 patients during a 18-month period study. Pattern 1 (10 patients) was consistent with HBV-2 infection. Reactivity of HbsAG was confirmed by neutralization tests; the absence of other markers was also verified, included anti-HBcIgM. Three of the patients were classified in high risk groups and seven in the low risk groups for hepatitis B; in none of them was co-infection with
hepatitis A
virus (HAV) detected. Pattern 2 (9 patients) was characterized by the detection of HBsAg and HBeAg and the absence of other hepatitis B markers. Six of these patients were
HIV
-positive patients and had increased and persistent levels (for longer than 12 weeks) of these markers. In the three remaining patients (with no underlying immunological disorders) there was a loss of these markers within a variable time (2 days to 16 weeks). Nevertheless, DNA-VHB was detected in one of these serum samples once all markers of virus B had disappeared.

Carbon-laden macrophages in bronchoalveolar lavage have been noted to be associated with a history of crack smoking. We report herein the finding of carbon-laden macrophages in four cytological preparations of pleural fluid from two crack smokers. The etiology of the two patients' pleural effusions differed; neither had a bronchopleural fistula. Patient 1 had AIDS, Pneumocystis carinii pneumonia, and Kaposi's sarcoma of the right lung with an associated bilateral pleural effusion. Patient 2 was
HIV
seropositive, had pulmonary tuberculosis,
hepatitis A
, B, and C, cardiomyopathy, pulmonary embolism, and bilateral pleural effusions, the latter of which were probably due to cardio-pulmonary dysfunction. An additional two crack smokers with pleural effusions due to malignancy, one primary pulmonary adenocarcinoma and the other metastatic melanoma, did not have carbon-like material in their pleural fluid cytology. We hypothesize that intracellular accumulation of carbonaceous material in the lung parenchyma and pleural space occurs when normal clearance mechanisms are overwhelmed.

The risk of acquiring diseases from transfusion of blood and blood products is well recognized and the issue of parvovirus in haemophiliacs is not a new one. We report two patients with haemophilia acquiring iatrogenic parvovirus B19 infection, resulting in life-threatening sepsis in one, and immunocompetent adult. Over the last 10 years there has been great progress in manufacturing safer products with regard to enveloped viruses such as
HIV
, hepatitis B and C. A recent outbreak across Europe of
hepatitis A
in haemophiliacs treated with plasma-derived factor VII concentrates has made haemophilic treaters concerned about the known (parvovirus B19 and
hepatitis A
) and the unknown non-lipid enveloped viruses that may be contained in the clotting factor concentrates, because these are resistant to the existing viral inactivating techniques. The possibility of
HIV
itself mutating into a non-lipid enveloped virus emphasizes the need to seek and use safer products.
