Abstract
INTRODUCTION In light of the COVID-19 pandemic, considerable effort is going into identifying and protecting those at risk. Criminalization, stigmatization and the psychological, physical, behavioural and economic consequences of substance use make people who inject drugs (PWID) extremely vulnerable to many infectious diseases. While relationships between drug use and blood-borne and sexually transmitted infections are well studied, less attention has been paid to other infectious disease outbreaks among PWID. DISCUSSION COVID-19 is likely to disproportionally affect PWID due to a high prevalence of comorbidities that make the disease more severe, unsanitary and overcrowded living conditions, stigmatization, common incarceration, homelessness and difficulties in adhering to quarantine, social distancing or self-isolation mandates. The COVID-19 pandemic also jeopardizes essential for PWID services, such as needle exchange or substitution therapy programmes, which can be affected both in a short- and a long-term perspective. Importantly, there is substantial evidence of other infectious disease outbreaks in PWID that were associated with factors that enable COVID-19 transmission, such as poor hygiene, overcrowded living conditions and communal ways of using drugs. CONCLUSIONS The COVID-19 crisis might increase risks of homelessnes, overdoses and unsafe injecting and sexual practices for PWID. In order to address existing inequalities, consultations with PWID advocacy groups are vital when designing inclusive health response to the COVID-19 pandemic.

Abstract
During 2002, an upsurge in frequency of hepatitis A outbreaks among injecting drug users was observed in England and Wales. As lack of risk factor information and the high mobility of the cases made linkage of outbreaks difficult, the relationship of nucleotide sequences in the VP1/2PA junction of the hepatitis A virus (HAV) genome amplified from serum of case-patients was investigated. A total of 204 HAV RNA positive sera obtained from a network of 23 laboratories were studied. Comparison of the sequences identified two principal strains: ES1 (n=95) belonging to type IB, and ES2 (n=72) to type IIIA. Of the remaining samples, 15 were type IA, 11 were type IB and 11 were type IIIA. ES1 predominated in Doncaster and other towns in Trent and northern England, and ES2 in the Midlands and southern England; the difference in geographical distribution between these two strains was significant (P<0.0001). In comparison to the sporadic cases, cases infected by either ES1 or ES2 tended to be younger, injecting drug users, people in contact with injecting drug users, or those with a history of incarceration in prisons or homelessness (P<0.0001). Cases infected by ES1 tended to be younger than those by ES2 (P<0.0001). The association of the outbreaks to two geographically restricted strains implicates two principal transmission pathways associated with injecting behavior. Identifying these routes may be conducive to preventing further outbreaks.

Abstract
BACKGROUND The authors report on the prevalence of, and risk factors for, hepatitis A virus (HAV) in a group of drug users in Italy. METHODS 404 heroin users were recruited and compared with a control group of 107 subjects in the general population. RESULTS Drug users born in north-eastern Italy have a prevalence of anti-HAV similar to the control group. A much higher prevalence was found in drug users born in southern Italy. CONCLUSION The similar prevalence of anti-HAV in drug users born in north-eastern Italy and in the general population, suggests that their lifestyle does not involve a substantial additional risk of HAV. The much higher prevalence found in drug users born in southern Italy is more likely to be related to infection during infancy.

Abstract
To describe an epidemiological investigation of an outbreak of hepatitis A virus (HAV) infection among injecting drug users in Aberdeen, Scotland. A case-control study to determine whether transmission was facilitated by poor personal hygiene or through sharing injecting equipment. Cases were more likely to report not washing their hands after using the toilet [odds ratio (OR) = 12.9, 95% confidence interval (CI) = 1.58-105.89] or before preparing food (OR = 4.0, 95% CI = 1.01-15.8), and less likely to have washed their hands prior to preparing drugs (OR = 10.67, 95% CI = 2.14-53.07). Cases were also more likely to report recipient sharing of needles/syringes (OR = 8.27, 95% CI = 1.68-40.57), and to have had injecting contact with someone who was jaundiced (OR = 29.4, 95% CI = 3.18-271.44). The results indicate that the lack of hygiene within the context of individuals gathering to prepare and inject drugs provides ample opportunity for the transmission of HAV. Although the promotion of good hygiene and the avoidance of sharing injecting equipment are important measures in preventing HAV transmission, they are unlikely to effect major behavioural change. Such measures should, therefore, be reinforced by routinely offering HAV vaccine to injectors.

Abstract
The hepatitis A virus (HAV), a picornavirus, is a common cause of hepatitis worldwide. Spread of infection is generally person to person or by oral intake after fecal contamination of skin or mucous membranes; less commonly, there is fecal contamination of food or water. Hepatitis A is endemic in developing countries, and most residents are exposed in childhood. In contrast, the adult population in developed countries demonstrates falling rates of exposure with improvements in hygiene and sanitation. The export of food that cannot be sterilized, from countries of high endemicity to areas with low rates of infection, is a potentially important source of infection. After ingestion and uptake from the gastrointestinal tract, the virus replicates in the liver and is excreted into the bile. Cellular immune responses to the virus lead to destruction of infected hepatocytes with consequent development of symptoms and signs of disease. Humoral immune responses are the basis for diagnostic serologic assays. Acute HAV infection is clinically indistinguishable from other causes of acute viral hepatitis. In young children the disease is often asymptomatic, whereas in older children and adults there may be a range of clinical manifestations from mild, anicteric infection to fulminant hepatic failure. Clinical variants include prolonged, relapsing, and cholestatic forms. Management of the acute illness is supportive, and complete recovery without sequelae is the usual outcome. Research efforts during World War II led to the development of passive immunoprophylaxis. Pooled immune serum globulin is efficacious in the prevention and attenuation of disease in exposed individuals. More recently, active immunoprophylaxis by vaccination has been accomplished. Future eradication of this disease can now be contemplated.

Abstract
Methamphetamine users are at increased risk of hepatitis A, but modes of transmission are unclear. The authors conducted a case-control study among methamphetamine users during an outbreak in Iowa in 1997. Twenty-eight reported, laboratory-confirmed, hepatitis A cases did not differ from 18 susceptible controls with respect to age, sex, or number of doses used. When compared with controls in multivariate analysis, case-patients were more likely to have injected methamphetamine (odds ratio (OR) = 5.5, 95% confidence interval (CI): 1.1, 27), to have used methamphetamine with another case-patient (OR = 6.2, 95% CI: 0.95, 41), and to have used brown methamphetamine (OR = 5.5, 95% CI: 0.51, 59). Receptive needle sharing was reported by 10 of the 20 case-patients who injected. Methamphetamine use with another case-patient was also associated with hepatitis A in an analysis restricted to noninjectors (OR = 17, 95% CI: 1.0, 630). During this outbreak, hepatitis A may have been transmitted from person to person among methamphetamine users through the fecal-oral and the percutaneous routes. Methamphetamine users should be vaccinated against hepatitis A and should be given immune globulin if they used methamphetamine with a case-patient in the last 2 weeks. Persons who intend to continue using methamphetamine should be advised about safer practices.

Abstract
We describe an outbreak among drug users of severe soft-tissue infections caused by a clonal strain of group A streptococcus of M-type 25. Cases (n = 19) in drug users were defined as infections (mainly needle abscesses) due to the outbreak strain. Comparison with controls showed that infected drug users bought drugs more often at a specific place. Drug purchase and use habits may have contributed to this outbreak.

Abstract
OBJECTIVE To describe five outbreaks of hepatitis A virus (HAV) infection associated with illicit drug use during a statewide outbreak of HAV infection in Queensland. DESIGN Risk factor prevalence survey. PATIENTS AND SETTING All 875 cases of HAV infection notified to Public Health Units in Queensland in the 12 months to 30 November 1997. MAIN OUTCOME MEASURE Type and prevalence of illicit drug use. RESULTS Risk factor assessment was completed for 804 cases (91.9%). We identified five outbreaks of HAV infection linked to illicit drug use. These outbreaks accounted for 24.6% (215/875) of all notified cases and 39% (190/482) of notified cases in the 15-34 years age group. The main type of illicit drug use in four of the five outbreaks was injecting drug use (74%; 118/160), while in the other outbreak it was sharing of smoking implements for marijuana (38%; 21/55). CONCLUSION Illicit drug use may be an under-recognised risk factor for HAV infection, particularly in young people. Faecal-oral transmission through poor personal hygiene, including sharing of implements for smoking marijuana, is the most probable route of transmission in these drug-linked outbreaks. The role of contaminated drug and needle-sharing remains to be clarified.

Abstract
This article describes a widespread outbreak of hepatitis A virus (HAV) infection amongst drug abusers in Finland. Although attempts to demonstrate the virus in amphetamines failed, the infection was assumed to be linked to intravenous use of the drug. The unusual mode of transmission prompted us to analyse possible atypical clinical features as well as the spread of the virus to the general population, nowadays practically without protective immunity. Serologically verified cases that occurred in Helsinki were interviewed, their hospital records were analysed and their contacts were serology tested. Amphetamine lots, as well as faecal samples from patients, were examined with RT-PCR. Detailed information was obtained from 238 subjects, among whom 131 admitted drug abuse and 67 cases were classified as secondary cases. Phylogenetic analysis of virus strains from HAV-infected cases suggested a common origin, and epidemiological observations linked it with particular lots of amphetamine. Three cases died, and 3 presented with severe clinical disease. Icterus was more common among i.v. drug abusers than others. Infection with hepatitis A virus was probably related to the faecal contamination of amphetamine associated with the transportation of the drugs in the gastrointestinal tract.

Abstract
The demographics, drug habits, and medical complications of a cohort of 1,129 addicts treated at Lexington in the period 1971-1972 were studied. These patients, admitted from 41 different states, had a mean period of addiction of 5.4 years. Over one-third of the sample had engaged in pimping or prostitution, and there were no differences by gender in terms of involvement. Eight-eight percent had shared injection equipment, and surprisingly, 78% admitted to some effort at sterilizing their "works." Hepatitis was the most common associated medical condition: 87% had serologic markers of hepatitis B virus (HBV) infection, 60% had evidence of hepatitis A virus (HAV) exposure, and 47% had abnormal liver function parameters. Gynecomastia was evident in 2% of male subjects. Thirteen percent of the sample had a reactive VDRL assay, but 64% of these were biologically false positive. Subtle abnormalities of immune function were also observed; 18% of the patients had recent unexplained weight loss, 6% had lymphadenopathy, 8% had leukopenia, and 2% had lymphocytopenia. We conclude that both HBV and HAV were important infectious disease risks in these addicts, and that many evidenced deficiencies in immune function well before AIDS became a major public health concern.

Abstract
Transmission of hepatitis A has been described in many settings, although few outbreaks have been reported among illicit drug users. We report six unrelated outbreaks of hepatitis A among users of marijuana and intravenously administered methamphetamine. Although the exact mode of transmission could not be determined, practices associated with illicit drug use may have facilitated transmission of hepatitis A. These outbreaks and other recent information indicate that illicit drug users may be at increased risk of acquiring hepatitis A infection.

Abstract
Prevalence of antibodies against hepatitis A (anti-HAV) among young Norwegian drug addicts in 1983 and the relative incidence of specific IgM against hepatitis A (anti-HAV IgM) during the years 1973-1983 have been studied. The survey is based on 1,689 serum samples from 561 persons submitted to hepatitis B screening or clinical hepatitis testing. The prevalence of anti-HAV in such groups was 43% in 1983 versus about 5% in corresponding age groups in the general population and 1% in the Norwegian U.N. soldiers in Lebanon. Presence of anti-HAV clearly correlated with presence of hepatitis B markers. Considerable fluctuations in the incidence of hepatitis A seemed to occur among drug addicts, with pronounced epidemic peaks in 1975 and 1979, coinciding with epidemics in Malmö, Sweden. Though the incidence varied, hepatitis A may have persisted among addicts for some years after 1979 in a semi-endemic manner. Although relatively young, most of them seem to have been in the milieu for some time before catching the infection. Drug addicts seem to be a target group for future hepatitis A vaccination programs.
