We report clinical profile of hundred and nine patients with SARS CoV-2 infection, and whole genome sequences (WGS) of seven virus isolates from the first reported cases in India, with various international travel histories. Comorbidities such as diabetes, hypertension, and cardiovascular disease were frequently associated with severity of the disease. WBC and neutrophil counts showed an increase, while lymphocyte counts decreased in patients with severe infection suggesting a possible neutrophil mediated organ damage, while immune activity may be diminished with decrease in lymphocytes leading to disease severity. Increase in SGOT, SGPT and blood urea suggests the functional deficiencies of liver, heart, and kidney in patients who succumbed to the disease when compared to the group of recovered patients. The WGS analysis showed that these isolates were classified into two clades: I/A3i, and A2a (four according to GISAID: O, L, GR, and GH). Further, WGS phylogeny and travel history together indicate possible transmission from Middle East and Europe. Three S protein variants: Wuhan reference, D614G, and Y28H were identified predicted to possess different binding affinities to host ACE2.

Background & objectives: Survival pattern among children infected with the human immune deficiency virus (HIV) follows a bimodel distribution. Some children survive beyond 9 years age and are known as long term survivers (LTS) while others had a more rapid course to death during the first few years of life. In the LTS group of children, two sub-populations have emerged, the long term non-progressors (LTNP) who have remained asymptomatic over a period of years and those who have survived despite clinical and laboratory evidence of disease progression, the long term progressors (LTP). The aim of the present study was to determine the factors influencing the conversion of LTNPs to LTPs in a group of perinatally HIV infected children who were followed up for five years. Methods: A total of 26 HIV seropositive paediatric patients were monitored from 2006 to 2011 with CD4 cell counts, onset of clinical manifestations, body weight, biochemical, haematological and immunological parameters. Statistical analyses, both qualitative and quantitative, were used to determine the degree of conversion of non-progressors to progressors. Results: All 26 (13 female and 13 male) perinatally HIV infected children, born during 1991-1996 were healthy until 2006. But by 2011, 18 were placed in progressors group with antiretroviral therapy (ART), while six remained in non progressors group and two died. As per the Kaplan-Meier survival analysis, AIDS free median survival period (years) in LTP group (CD4 count) of the cohort was 10±0.66 (<200; P=<0.05); 11±0.61 (200-350, P=<0.05), 12±0.18 (>350, P=<0.05). Intercurrent and opportunistic infections (OIs) were observed in LTPs only. The incidence of OI in LTPs was higher when compared to general paediatric population. Interpretation & conclusions: Our findings show that CD4 counts and OIs play an important role in influencing the survival chances of perinatally HIV infected children. [ABSTRACT FROM AUTHOR]

HIV/AIDS pandemic has devastated many countries reversing national development; HIV was not seen in Asia and India till 1980. Now India has become epicenter of AIDS pandemic. During April 2002 to March 2003 the HIV+ ve pregnant women and their husbands were encouraged to enroll in the prospective study with informed consent. The study results consist of most of the females who are in the age group between 16-25 years who were affected by HIV High infection is observed in people with lower socio-economic and education background. High infection rate is observed in house wives (26.7%), laborers (23%) and agricultural workers (12.1%) followed by toddy tapers (5%), drivers (5.96%) and others (6 47%). HIV +ve subjects at Mother To Child Transmission (MTCT) centers are surprisingly clinically very healthy. No disease manifestation was noticed.
