Rubella infection in pregnant women during the first trimester of pregnancy can lead to fetal anomalies, commonly known as congenital rubella syndrome (CRS). The objective of our study was to analyze the serological test results among infants suspected of having CRS aged < or = 12 months compared with their clinical status. Between January 2002 and December 2011, 3,279 serum samples from infants aged < or = 12 months from government hospitals in Malaysia were examined for rubella specific IgM and IgG antibodies using a Axsym, automated analyzer (Abbott Laboratories). Forty-eight samples were positive for rubella specific IgM antibodies and 494 samples were positive for rubella specific IgG antibodies. These were then age stratified and their clinical history reviewed for any CRS symptoms. Fifteen of 38 rubella IgM positive infants (39.5%) aged < 3 months, had a clinical appearance compatible with CRS. However, only 1 IgM positive infant aged 3 to 6 months and one infant aged 7 to 11 months had clinical appearance compatible with CRS. The most common abnormal findings in these cases were congenital heart defects and cataracts. Forty-eight point eight percent of IgM positive cases and 53.1% of IgG positive cases, had inadequate information in the chart to determine the presence of CRS. Clinical findings and timely laboratory diagnosis to determine the presence of CRS are important in infants born with congenital defects. Physicians should also be aware of the appropriate interpretation of these findings.
An effective live attenuated rubella vaccine was available since 1969 and congenital rubella syndrome can be prevented with appropriate vaccination. We report a baby with congenital rubella syndrome born in Klang valley to indicate that the Universal Rubella Vaccination Programme adopted by the Ministry of Health Malaysia since 2002 has yet to achieve its effect of eliminating transmission of rubella and preventing congenital rubella infection in the community. To our knowledge, the virus isolate represents the first successful isolation of rubella virus in this country and will serve as the reference strain for future comparison in molecular epidemiological tracking of rubella virus activity this country.
Rubella is generally a mild and self-limited disease in children. During pregnancy, rubella can have potentially devastating effects on the developing fetus. Postnatal rubella is transmitted primarily by inhalation of virus-laden airborne droplets or direct contact with infected nasopharyngeal secretions. In susceptible pregnant women, the virus may cross the placenta and spread through the vascular system of the developing fetus. Postnatally acquired rubella typically begins with fever and lymphadenopathy, followed by an erythematous, maculopapular rash. The rash classically begins on the face, spreads cephalocaudally, becomes generalised within 24 hours, and disappears within 3 days. Maternal rubella, especially during early pregnancy, may lead to miscarriage, intrauterine fetal death, premature labour, intrauterine growth retardation, and congenital rubella syndrome. Cataracts, congenital heart defects, and sensorineural deafness are the classic triad of congenital rubella syndrome and they typically occur if the fetal infection occurs in the first 11 weeks of gestation. Laboratory confirmation of rubella virus infection can be based on a positive serological test for rubella-specific immunoglobulin M antibody; a four-fold or greater increase in rubella-specific immunoglobulin G titres between acute and convalescent sera; or detection of rubella virus RNA by reverse transcriptase-polymerase chain reaction. Treatment is mainly symptomatic. Universal childhood immunisation and vaccination of all susceptible patients with rubella vaccine to decrease circulation of the virus are cornerstones to prevention of rubella and, more importantly, congenital rubella syndrome.
INTRODUCTION: Rubella infection during early pregnancy may cause fatal consequences such as congenital rubella syndrome (CRS). The incidence rate (IR) of CRS confirmed cases in Yogyakarta, Indonesia between July 2008 and June 2013 was high at 0.05 per 1,000 live births. This study aimed to discover the spatiotemporal pattern of rubella and CRS and also identify whether the proximity of rubella cases was associated with the occurrence of CRS cases.
METHODS: This observational research used a spatiotemporal approach. We obtained CRS and rubella surveillance data from Dr. Sardjito Hospital, Provincial, and District Health Offices in Yogyakarta, Indonesia during January-April 2019. The home addresses of rubella and CRS cases were geocoded using the Global Positioning System. Average of the nearest neighbour and space-time permutation analyses were conducted to discover the spatiotemporal patterns and clusters of rubella and CRS cases.
RESULTS: The peak of rubella cases occurred in 2017 (IR: 22.3 per 100,000 population). Twelve confirmed cases of CRS were found in the 2016-2018 period (IR: 0.05 per 1,000 live births). The occurrence of CRS in Yogyakarta was detected 6-8 months after the increase and peak of rubella cases. The spatiotemporal analysis showed that rubella cases were mostly clustered, while CRS cases were distributed in a dispersed pattern. Rubella cases were found within a buffer zone of 2.5 km from any CRS case.
CONCLUSIONS: Rubella cases were spatiotemporally associated with the occurrence of CRS in Yogyakarta. We recommend strengthening the surveillance system of CRS and rubella cases in order to contain any further spreading of the disease.
The prevalence of ocular abnormalities was studied in 165 children from a Malaysian school for the deaf. Ninety-five children (57.6%) had one or more ocular abnormalities. Rubella retinopathy was the commonest form of ocular abnormality (35.2%). Refractive errors were found in 23 children (13.9%). Refractive errors in the rubella group were significantly more common than in the non-rubella group of deaf children (p < 0.001) (chi 2 test). Thirteen children had congenital anomalies causing significantly impaired vision. Ophthalmological examination of deaf children helps in the detection of cases with rubella eye signs and thus helps to identify the cause of deafness. Since deaf children are at greater risk of visual and ocular abnormalities, periodical ophthalmological examination should be carried out in these children.
This was a 28-year-old mentally-challenged girl with underlying congenital Rubella syndrome. She was bilaterally aphakic after congenital cataract surgery. She then developed bilateral aphakic glaucoma and had to undergo multiple glaucoma filtering surgeries. The most recent procedure she had undergone for her left eye was a second Ahmed valve implantation with an overlying sclera patch. Postoperatively, intraocular pressure was well controlled. However, nine months later, slit lamp examination revealed the tube was adherent to the overlying cornea with surrounding deep and superficial cornea vascularization. Siedel test was negative and intraocular pressure was normal. Subsequently the tube was removed but the plate was left in situ.
INTRODUCTION: routine rubella antibody screening is not done for antenatal mothers in community health clinics in Malaysia. However, congenital rubella syndrome has persisted with its associated health burden.
OBJECTIVES: to determine the prevalence of rubella susceptibility among pregnant mothers and its associated risk factors.
METHODOLOGY: a cross-sectional study was carried out in the Petaling district, Selangor, Malaysia, where 500 pregnant mothers were recruited, and face-to-face interviews were conducted. Rubella IgG tests were performed.
RESULTS: the prevalence of rubella susceptibility among pregnant mothers was 11.4%. Using logistic regression, a history of not having received rubella vaccination or having unknown rubella vaccination status was found to be a significant predictor for mothers to be rubella susceptible (odds ratio = 2.691; 95% confidence interval = 1.539-4.207).
CONCLUSIONS: routine rubella IgG screening tests need to be offered to all antenatal mothers in view of the high prevalence found.

Malaysia is a rapidly developing country with a very young population, about 36% of which are below the age of 15 years. The standard of child health has improved greatly. However, there are great changes in the morbidity and mortality patterns of childhood diseases relating mainly to an improved standard of living; availability of safe water supply and adequate sanitary latrines; a higher literacy rate; rapid industrialisation and urban migration. The infant mortality rate has droppedfrom 50.1 per 1,000 livebirths in 1986 to 10.4 in 1995, and similar trends apply also to neonatal, perinatal and toddler mortality rates. Nevertheless, current major child health problems are those relating to events in the perinatal period and to infections. Despite improvements in the standard of neonatal care with the use ofhigh technology, the commonest cause of certified deaths still occur in the neonatal period. A rapid and inexpensive screening test for G6PD deficiency, a disease present in 2-3% of the population, is now widely available and, together with the use of phototherapy is largely responsible for the declining incidence of kernicterus in the country. Infections remain an important cause of morbidity and mortality although their patterns have changed. The very high (>95%) WHO-EPI-vaccines coverage rate is linked to the great reduction in the incidence of diphtheria, pertussis, tetanus, poliomyelitis and measles. Childhood tuberculosis is less common now, with about 250 - 300 reported cases per year and TB meningitis is rare with about 30-40 reported cases/year. The hepatitis B carrier rate is high (5%) and the introduction of routine newborn hepatitis B vaccination in 1989 is expected to have a positive impact as is the immunisation of young girls against rubella introduced in 1985 in reducing the incidence of congenital rubella syndrome. The incidence of malaria has declined but remains prevalent in the interiors of PeninsularMalaysia and in Sabah and Sarawak. Filariasis is largely under control. Unfortunately, despite great efforts at mosquito control, dengue virus infection remains a major problem with thousands of cases reported every year. Children are most susceptible to dengue haemorrhagic fever with many dying from the shock syndrome. The incidence of acute gastroenteritis has also dropped with most cases being due to a viral aetiology. Acute respiratory infections, mostly viral in origin, account for most attendances at paediatric outpatient services. Although staphylococcal and streptococcal impetigo and pneumonia are common, the incidence of streptococcal related diseases like rheumatic fever and acute glomendonephritis is rapidly declining. The nutritional status of children has improved in tandem with the rise in the standard of living, but subclinical malnutrition is prevalent, particularly among urban squatters and the rural poor. There is a disturbing decline in breastfeeding among urban working mothers. Poor weaning practices and food habits are responsible for the common occurrence of nutritional anaemia (5%) among infants and young children. Greater prosperity, rapid industrialisation and urbanisation have resulted in changes in the childhood disease pattern where non-communicable diseases assume greater importance as the problems of malnutrition and infection are gradually overcome. Road traffic accidents are a major killer and home accidents, largely preventable, are an important cause of morbidity and mortality. Childhood cancer, with about 550 new cases a year, is an important cause of death beyond infancy. Major congenital malformations, with a 1% prevalence rate, cause much ill-health. Thalassaemia is a particularly common genetic disease with fl thalassaemia gene frequency of about 5%. The prevalence of asthma is increasing, with a rate of 13.9% in the Kiang Valley but the prevalence of asthma-related symptoms is much higher. Physical, sexual child abuse and neglect, abandoned babies, substance abuse are but signs of stress of modern city living and peoples inability to cope with it. Although the general standard of child health has greatly improved, there are several states where it is still not satisfactory. In Sabah where there is a large illegal immigrant population, the infant mortality and infection rates are relatively high. In Kelantan and Trengganu, it is common for parents to refuse permission for a lumbar puncture required to treat meningitis. Other still deeply entrenched, culturally-related adverse health practices include : a fatalistic attitude to illness; a preference for traditional practitioners of medicine resulting in late treatment; and 'doctor-hopping' with unrealistic expectations of 'instant cure'. Childhood illnesses that are uncommon in Malaysia include: cystic fibrosis, coeliac disease, ulcerative colitis, Crohns disease, Sudden Infant Death Syndrome, Encopresis, enuresis and epiglottitis due to Haemophilus Influen:ae.
