Abstract
Background India experienced three coronavirus disease (COVID-19) waves, with the third attributed to the highly contagious Omicron variant. Before the national vaccination rollout for children above 6, understanding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) positivity in the pediatric population was essential. This study aims to assess the burden of Covid-19 infection and to estimate the seroprevalence in children aged 6 to 14 years in the state of Karnataka. Material and Methods We surveyed 5,358 children aged 6-14 across Karnataka using 232 health facilities, from June 6 to 14, 2022. We determined the sample size using the PPS (Population Proportional to Size) technique and employed cluster sampling. We tested all participants for SARS-CoV-2 IgG with an enzyme-linked immunosorbent assay (ELISA) kit and SARS-CoV-2 RNA with reverse transcription-polymerase chain reaction (RT-PCR). We sequenced samples with a cycle threshold (CT) value below 25 using whole genomic sequencing (WGS). Result We found an adjusted seroprevalence of IgG at 75.38% statewide, and we found 0.04% of children RT-PCR positive for COVID-19. We determined a case-to-infection ratio of 1:37 and identified the SARS-CoV-2 strains as Omicron, BA.5, and BA.2.10. Conclusion The study showed a high seroprevalence of IgG among children with low active infection. Omicron, BA. 5, and BA. 2.10 variants were detected through WGS.

Abstract
A meta-analysis was done to study the relationship between antigenecity and immunogenecity of human rabies vaccines. The data of ten cell culture human rabies vaccine studies conducted at a single centre during 1993-2004 were used in the study. The vaccines studied included Purified Chick Embryo Cell Vaccine (Kaketsuken, Japan and Rabipur, India), Purified Vero cell Rabies Vaccine (Verorab, France), Human Diploid Cell Vaccine (MIRV, France and Rabivax, Adsorbed and Lyophilized, India) and Rhesus Diploid Rabies Vaccine (adsorbed, USA). Interestingly, it was revealed that an higher antigenecity of rabies vaccines viz. potency of > or = 5 IU per single intramuscular dose did not result in significantly higher immunogenecity, as measured by rabies virus neutralizing antibody (RVNA) titers in the vaccinees, both on day 14 (t = 0.42, p > 0.66, GMR = 1.06, 95% CI of GMR = 0.82, 1.37) and day 90 (t = 0.80, p > 0.43, GMR = 1.15, 95% CI of GMR = 0.74, 1.14). However, as there are no reports of meta-analysis of cell culture human rabies vaccine trials, to confirm this observation the authors recommend further studies in this regard.

Abstract
Fourteen pregnant women who received rabies post-exposure prophylaxis (PEP) at the anti-rabies clinic (ARC) of Kempegowda Institute of Medical Sciences (KIMS) were followed up for assessing the safety of modern rabies vaccines and equine rabies immunoglobulin (ERIG) in pregnancy. The women were in the age range of 18-28 years, mostly from urban area (64%) and exposed to suspect rabid dogs (86%). They had received purified vero cell rabies vaccine (Verorab = 8 and Abhayrab = 4), purified chick embryo cell vaccine (Rabipur = 2) by Essen regimen; and equine rabies immunoglobulin (Equirab = 7 and Pasteur anti-rabies serum = 1). None of the pregnant women reported any adverse events to either vaccine or equine rabies immunoglobulin. All had safe vaginal deliveries and in all cases both the mother and the child were found to be healthy and normal.

Abstract
BACKGROUND Human rabies is an ongoing significant public health problem inmany developing countries, with India reporting the highest incidence of rabies-related deaths (∼20,000 per year). Many people living in India cannot afford the standard IM postexposure prophylaxis (PEP) with cell-culture vaccines, which are administered using a 5-dose regimen developed in Essen, Germany. A potentially less expensive intradermal (ID) regimen, based on the Essen regimen, has been developed at the Kempegowda Institute of Medical Sciences (KIMS), Bangalore, India. OBJECTIVE The objective of this study was to compare the immunogenicity and local and systemic tolerability of the KIMS-1D regimen with those of the standard Essen IM regimen in healthy adult volunteers in India. METHODS This randomized, open-label, active-controlled trial was conductedat the Antirabies Clinic, Medical College, KIMS. Healthy adult volunteers were randomly assigned to receive purified chick embryo cell vaccine (PCECV) using the KIMS-1D regimen (0.1 mL injected ID at 2 body sites on days 0, 3, 7, 14, and 28 ["2-2-2-2-2"]) or the Essen IM regimen (1 mL injected IM at 1 body site on the same days Subjects were followed up for 365 days by the treating physician and encouraged to voluntarily report any adverse events (AEs). Serum rabies virus-neutralizing antibody (RVNA) concentrations were measured before the first injection on day 0 (baseline) and on days 14, 28, 90, 180, and 365, using the rapid fluorescent focus inhibition test. RESULTS Ninety-one subjects were enrolled and included in the tolerabilityand immunogenicity analyses. The ID group comprised 45 subjects (26 men, 19 women; mean [SD] age, 20.84 [1.48] years); the IM group, 46 subjects (28 men, 18 women; mean [SD] age, 21.02 [1.16] years). The most common local AEs were pain at the injection site (2/225 [0.9%] in the ID group and 10/230 [4.3%] in the IM group; P < 0.006) and itching at the injection site (5/225 [2.2%] in the ID group and none in the IM group; P = 0.026). All of the AEs were transient and resolved without the need for medication. All subjects had serum RVNA concentrations ≥0.5 IU/mL-considered protective by the World Health Organization-at all follow-up visits. However, the mean RVNA concentrations in the IM group were significantly higher compared with those in the ID group from days 14 to 365 (all, P < 0.001). CONCLUSION In this study in healthy volunteers, PEP with PCECV administered using the KIMS-ID regimen was well tolerated and immunologically efficacious for 365 days. Adequate RVNA levels were maintained with the KIMS-ID regimen from days 14 to 365, although these levels were significantly lower than those achieved in the group receiving the Essen IM regimen (all, P < 0.001).

Abstract
BACKGROUND Rabies immunoglobulins are life-saving in patients with severe exposure to rabies. Despite the high degree of purification of equine rabies immunoglobulin (ERIG), the product inserts still recommend a skin sensitivity test before administration of this heterologous serum. A recent WHO recommendation states that there are no scientific grounds for performing a skin test before administering ERIG because testing does not predict reactions and it should be given irrespective of the result of the test. In this conflicting situation, we assessed the use of the skin sensitivity test in predicting adverse events to ERIG. METHODS The data analysed were from the Antirabies Clinic of the Kempegowda Institute of Medical Sciences Hospital, Bengaluru, India. The period of study was 26 months (June 2008-July 2010). The skin sensitivity test was validated by evaluating its sensitivity, specificity, predictability, falsepositive and false-negative results. RESULTS A total of 51 (2.6%) adverse events were reported in 31 (1.5%) subjects. Most of these were mild to moderate in nature and subsided without medication. There was no serious adverse event. The sensitivity and specificity of the skin sensitivity test to predict an adverse event was 41.9% and 73.9%, respectively. CONCLUSION Our experience with the skin sensitivity test suggests that it may not be required before administering ERIGs, as recommended by WHO.

Abstract
A survey of 23 infectious diseases (ID) hospitals/ID wards of general hospitals was done during 2008-09 to assess the facilities for and management of rabies patients. All were Government hospitals and 0.5% of total beds was earmarked for rabies cases. The hospitals were mostly run by medical colleges (47.8%) and ID hospitals (30.4%) and located outside city limits (52.2%). The patients were admitted to 'rooms (39.1%)' and 'wards (43.5%)'. The general conditions of rabies sections i.e. sanitation and linen (65%), space and toilet (52% and 56%) and bed (47.8%) require improvements. There is a need to improve staff availability, use of personal protective wears, preventive vaccination of care providers and medicinal supplies. It is recommended to encourage hospitalization of human rabies cases to ensure a 'painless and dignified death' and this must be considered as a 'human rights' issue.

Abstract
OBJECTIVES The present study was undertaken to standardize skin testing and to develop a safe and effective premedication protocol for administration of ERIG in those with skin test positivity/hypersensitivity. METHODS A method of grading of skin testing was developed using injection histamine as a positive control. This was evaluated by using it on 517 subjects who had severe (WHO category III) exposure to rabies. A premedication protocol consisting of injections pheniramine, ranitidine, hydrocortisone and adrenaline was evaluated by using it on fifty one subjects who were skin test positive/hypersensitive to ERIG. RESULTS The premedication protocol was safe and effective as all the S1 subjects could be administered the full dose of ERIG despite being skin test positive/hypersensitive to ERIG. Besides the premedication drugs/protocol did not affect the immune response to vaccine and ERIG therapy.

Abstract
OBJECTIVE Human rabies has been endemic in India since time immemorial, and the true incidence of the disease and nationwide epidemiological factors have never been studied. The main objectives of the present study were to estimate the annual incidence of human rabies in India based on a community survey and to describe its salient epidemiological features. METHODS The Association for Prevention and Control of Rabies in India (APCRI) conducted a national multi-center survey with the help of 21 medical schools during the period February-August 2003. This community-based survey covered a representative population of 10.8 million in mainland India. Hospital-based data were also obtained from the 22 infectious diseases hospitals. A separate survey of the islands of Andaman, Nicobar, and Lakshadweep, reported to be free from rabies, was also undertaken. RESULTS The annual incidence of human rabies was estimated to be 17,137 (95% CI 14,109-20,165). Based on expert group advice, an additional 20% was added to this to include paralytic/atypical forms of rabies, providing an estimate of 20,565 or about 2 per 100000 population. The majority of the victims were male, adult, from rural areas, and unvaccinated. The main animals responsible for bites were dogs (96.2%), most of which were stray. The most common bite sites were the extremities. The disease incubation period ranged from two weeks to six months. Hydrophobia was the predominant clinical feature. Many of the victims had resorted to indigenous forms of treatment following animal bite, and only about half of them had sought hospital attention. Approximately 10% of these patients had taken a partial course of either Semple or a cell culture vaccine. The islands of Andaman, Nicobar, and Lakshadweep were found to be free of rabies. CONCLUSION Human rabies continues to be endemic in India except for the islands of Andaman, Nicobar, and Lakshadweep. Dogs continue to be the principal reservoir. The disease is taking its toll on adult men and children, the majority from rural areas, due to lack of awareness about proper post-exposure immunization. The keys to success in the further reduction of rabies in India lies in improved coverage with modern rabies vaccines, canine rabies control, and intensifying public education about the disease.

Abstract
BACKGROUND At present, in the event of re-exposure to rabies, 2 booster doses are recommended for people who have been previously vaccinated with cell culture rabies vaccines by the conventional intramuscular route. As the intradermal route of vaccination is likely to be introduced in the future, we investigated the immune response to a cell culture rabies vaccine after crossing over from the intramuscular to the intradermal route and vice versa. METHODS Twenty healthy adult volunteers who had received a primary course of rabies vaccination with purified chick embryo cell rabies vaccine by either the intramuscular (n = 10) or intradermal (n = 10) route received booster vaccination with the same vaccine by the alternative route. The regimen used was 0.1 ml of vaccine by the intradermal route at two sites (deltoid area) for the intramuscular group, or 1 ml of vaccine by the intramuscular route (deltoid muscle) to the intradermal group on days 0 and 3. RESULTS There was a 15-fold rise in the rabies virus neutralizing antibody response both by the intradermal and intramuscular routes of booster vaccination (p < 0.0001). Thus, the change of route of purified chick embryo cell booster vaccination did not alter the anamnestic immune response to the vaccine. No side-effects were observed after vaccination with either of the routes. CONCLUSION Purified chick embryo cell vaccine was found to be safe and immunologically efficacious following booster vaccination after cross-over from the intradermal to the intramuscular route and vice versa.

Abstract
This was a WHO sponsored national multi-centric rabies survey and one of its objectives was to find out the incidence of animal bites, anti-rabies treatment practices, Pet dog population and their care. Twenty-one medical colleges chosen with geoscatter representation conducted the survey during February-August, 2003. The survey was conducted in 18 states, covering a population of 52,731 chosen randomly from 8500 households. The annual incidence of animal bites was high, 1.7% and it was more in rural areas (1.8%), children (2.6%) and poor/low income group (75%). The main biting animal was dog (91.5%), mostly stray (63%), followed by cat (4.7%). A high proportion of bite victims did not wash their wounds with soap and water (39.5%), preferred Government hospitals (59.9%) and nerve tissue vaccine (46.9%). The use of rabies immunoglobulin was low (2.1%). A single animal bite episode led to a loss of 2.2 man-days and the cost of medicines including anti-rabies vaccine was Rs.252 (US$6). The recourse to indigenous treatment (45.3%) and local application to wound (36.8%/) was quite prevalent. About 17% of households reported having a pet/domesticated dog and the pet dog: man ratio was 1: 36. Pet dog care/management practices were not satisfactory with a low veterinary consultation (35.5%) and vaccination (32.9%). The situation was slightly better in urban areas. The people also reported the presence (83%) and menace (22.8%) of stray dogs. It is recommended to initiate appropriate community awareness and dog vaccination campaigns and effective stray dog control measures.

Abstract
The Islands of Andaman and Nicobar and Lakshadweep have been reported to be rabies free from time immemorial. Recently, a survey of the islands of Andaman and Nicobar & Lakshadweep was done between July and August 2003 to assess their rabies free status. It was revealed that these islands continue to remain rabies free. However, in Andamans the increasing dog population, poor vigil on import of dogs and lack of laboratory surveillance for rabies posed a threat to this status. The Lakshadweep islands, which are free of dogs, however, faced a threat from the lack of vigil on the entry and presence of cats and poor surveillance for rabies in them.

Abstract
This survey was conducted by using a 30 cluster random sampling technique to comprehensively study the nature and magnitude of rabies and its related problems in human and dog population. The city has an estimated dog population of 3.25 lakhs of which 2 lakhs (61.5%) are stray dogs and 1.25 lakhs (38.5%) are pet dogs. The dog:man ratio was about 1:12 and the pet:stray dog ratio of 1:2. The awareness about Animal Birth Control (ABC) programme was low (34%) and only 20% had faith in it. The annual incidence of dog bites was 1.9% persons. It was more in males (64%) and mostly from stray dogs (64%). About 86% of them received anti-rabies vaccination and none received life saving Anti-Rabies Serum (ARS). The annual incidence of human rabies was 15 and dog rabies 58 resulting in a ratio of 1:4 approximately as a rabies contagion index. The implementation of ABC programme was weak (10.4% coverage) and is recommended for acceleration and improvement. Similarly modern anti-rabies immunization, including anti-rabic serum, shall replace the outdated sample (sheep brain) vaccine.

Abstract
This study was conducted with the main objective of determining the safety and immunogenicity of purified vero cell rabies vaccine (PVRV) during pregnancy. Twenty nine pregnant women exposed to rabies were vaccinated with PVRV as per the Essen regimen advocated by World Health Organization. None of the women experienced any adverse side effects to the vaccine. The intrauterine growth and development monitored by ultrasound examination was found to be normal and the outcome of pregnancy was satisfactory. There were no congenital anomalies in any of the infants born and they were healthy and had normal growth and development during the one year follow-up period. The rabies neutralizing antibody titers from day 14 to day 365 following vaccination in these women was adequate and well above the minimum protective level of 0.5 iu/ml of serum. Protective levels of antibodies were also present in serum of some of the babies tested, for up to 3 months of age. The mothers and infants followed for one year period were doing well at the end of the study period. Consequently, PVRV was found safe and immunogenically efficacious during pregnancy.

Abstract
The present controlled clinical trial evaluates the immunoresponse to Purified Verocell Rabies Vaccnine (PVRV) by Essen schedule of vaccination during Pregnancy. Seventeen Pregnant women with history of animal bites who received PVRV as per Essen regimen were matched for the confounding variables of age, socio-economic status and doses of PVRV received with seventeen "Non-pregnant women". The mean age was about 24 years, majority (70.6%) belonging to middle socio-economic group and received 3 doses of PVRV. Contrary to the expectations the rabies neutralizing antibody titres were slightly higher in pregnant women (except day 180) but the difference was not significant (P > 0.2). Both the groups of women had antibody titres above protective level (0.5 IU/ml) from day 14 till day 365 thus indicating immunogenic efficacy of PVRV by Essen regimen during Pregnancy.

Abstract
Animal bites and so also the incidence of rabies in India are on rise. There are regional differences in the animal responsible for the bite. Different practices including use of traditional remedies are prevalent for wound treatment. In India this report analyses the profile and characteristics of animal bites in 869 patients from various regions. Apart from dog and cat, other animals such as cow, monkey, horse, pigs, camel were responsible for bite and could be possible vectors in transmission of rabies. Traditional remedies such as application of chilly paste is still practiced in state of Rajasthan.

Abstract
This study was conducted to know whether prisoners constitute a "high risk group" for HIV transmission in India today. A sero-epidemiological period prevalence survey was conducted in Central Prison, Bangalore, South India covering 1007 undertrials and 107 permanent convicts during January to December 1993. Twenty (1.98%) undertrials and none of the permanent convicts were seropositive for HIV infection. All of them were males and 1.6(80%) of them were in the age group of 20-30 years. Low literacy, poor income, sexual promiscuity and low condom usage were observed among the seropositives. Thus, prisoners constitute a high risk group and routine screening and counselling are recommended.

Abstract
This multicentric study was conducted with the aim of knowing the nature and magnitude of the problem of rabies in Bangalore city. The disease was enzootic and endemic and the principal reservoir of infection was dog. There was stray dog menace due to ineffective dog control measures. Nearly 30% of animal bite victims did not wash their wounds and about 60% of patients started antirabic vaccine late after 24 hours of bite. The antirabies serum (equine) was not available at all. The victims of hydrophobia were both children (37.5%) and adults (62.5%) and the average incubation period ranged from 35-111 days. Pre-exposure antirabic vaccination was not given to dog catching and dog pound staff. Lastly, there was lack of proper laboratory diagnostic facilities for rabies in Bangalore.

Abstract
The cold chain plays a major role in the universal immunization programme which helps in preventing against six major killer diseases in children. We collected 144 study samples randomly from different parts of Bangalore to know the training status of personnel, refrigeration facilities, storage, monitoring and potency of vaccines. It was observed that 6.6% of general practitioners were trained under Universal Immunization Programme, monitoring was not satisfactory, and two of the OPV samples from medical practitioners had an unsatisfactory titre dose. Comprehensive orientation/training on cold chain is essential for medical practitioners and other professionals.
