Efficacy of Natural Immunity against SARS-CoV-2 Reinfection with the Beta Variant

Difficulty in breathing or shortness of breath may be simply termed as Shwasa (Asthma), As per Ayurveda, Shwasa is mainly caused by the Vata and Kapha Doshas. Shwasa is broadly classified into five types in Maha Shwasa (Dyspnoea major), Urdhawa Shwasa (Expiratory Dyspnoea), Chinna Shwasa (Chyne-stroke respiration), Kshudra Shwasa (Dyspnoea minor), Tamaka Shwasa (Bronchial Asthma). In modern science Tamaka Shwasa can be correlated with Asthma, Asthma which is a chronic inflammatory disease of airway. In modern medicine there is no cure for Asthma, symptoms can typically be improved. In Ayurveda, Asthma can be effectively and safely manage the condition without inducing any drug dependency where Pachakarma procedures and use of internal medication detoxifies the body, provides nutrition and increases the elasticity of lung tissue it also develops natural immunity of the body thus decreasing episodic recurrence of the disease.

Abstract COVID-19 caused by SARS CoV2 (The novel corona virus) has already taken lives of many people across the globe even more than anyone could have imagined. This outbreak occurred in China and since then it is expanding its devastating effects by leaps and bounds. Initially it appeared to be an outbreak of pneumonia but soon it was found to be much more than that and the infectivity was found to be very high. This is the reason that it has taken whole globe in its trap and become a pandemic in such a short span of time. Death is occurring because it is a new virus and human body has no specific antibodies for it. Presently there is no approved vaccine so everyone is susceptible but people with co-morbidities appear to be in more risk and the best way for protection is social distancing and increasing one’s natural immunity by taking healthy diet and exercise. When a person is infected the clinical presentation ranges from asymptomatic to severe ARDS, sudden onset of anosmia, headache, cough may be the initial symptoms. This review is focused on immunopathology and effect of COVID-19 on neurological disorders and also the neurological manifestations and the treatment.

AbstractCOVID-19 vaccination is being conducted in over 200 countries and regions to control SARS-CoV-2 transmission and return to a pre-pandemic lifestyle. However, understanding when non-pharmaceutical interventions (NPIs) can be lifted as immunity builds up remains a key question for policy makers. To address this, we built a data-driven model of SARS-CoV-2 transmission for China. We estimated that, to prevent the escalation of local outbreaks to widespread epidemics, stringent NPIs need to remain in place at least one year after the start of vaccination. Should NPIs alone be capable of keeping the reproduction number (Rt) around 1.3, the synergetic effect of NPIs and vaccination could reduce the COVID-19 burden by up to 99% and bring Rt below the epidemic threshold in about 9 months. Maintaining strict NPIs throughout 2021 is of paramount importance to reduce COVID-19 burden while vaccines are distributed to the population, especially in large populations with little natural immunity.

Abstract Background Adequate vaccination coverage among healthcare workers, including students in healthcare professions (SHPs), is crucial in order to prevent spreading of infections within healthcare facilities. However, vaccination coverage among SHPs is often inadequate. We aimed to describe the vaccination/immunization status of SHPs of the University of Milan. Methods We spread an e-survey to the academic e-mail addresses of postgraduate medical residents and to first- and last-year undergraduate SHPs. The questionnaire covered sociodemographic data (age, sex, education, municipality of residence, internship in high-risk wards) and the reported vaccination/immunization status for Influenza (previous flu season), Varicella, MPR and DTaP vaccines. Results Among 5743 invited SHPs, 884 participated in the survey. The study sample comprised 462 medical residents and 422 undergraduate SHPs (medicine 176, nursery 186, midwifery 4, healthcare assistance 32, prevention techniques 24). Median age was 27 years (IQR 7); 68.4% participants were female; 91.3% had attended high school in a lyceum, while others in a professional (2.9%) or technical (5.8%) institute; 36.7% lived in municipalities of < 20.000 inhabitants, while 26.1% of > 250.000. Traineeships took place in high-risk wards for 46% of participants. Reported vaccination coverage for Influenza was 33,7% (with higher coverage for pediatric nursing and midwifery students, medicine students and medical residents). Participants reported immunity (either vaccine or natural immunity) to Varicella in 93,3% cases. Declared vaccination coverage for Hepatitis B was 94,1%; 91,7% participants reportedly completed the MPR schedule, 76,2% the recommended DTaP booster. Conclusions Influenza vaccination coverage was suboptimal in our sample of SHPs, suggesting the need of specific educational programs and targeted vaccination campaigns, which may help shaping a positive vaccination attitude for future healthcare professionals. Key messages Immunization status for VPDs is suboptimal among Italian students in healthcare professions. The monitoring of the immunization status should include healthcare students actively involved in healthcare activities.

ABSTRACT Typhoid fever is a major public health problem in developing countries, conservatively estimated to occur in 17 million cases and be responsible for 200,000 deaths annually. We investigated the acquisition of natural immunity to Salmonella enterica serovar Typhi in a region where typhoid is endemic by testing sera from an age-stratified sample of 210 healthy participants in Kathmandu, Nepal, for bactericidal activity toward S. Typhi and for anti-Vi capsular polysaccharide antibodies. Bactericidal titers in children were significantly lower than those in newborns and adults (P < 0.0001). Anti-S. Typhi bactericidal geometric mean titers were age dependent, increasing 10-fold during childhood. Anti-Vi polysaccharide antibody geometric mean concentrations were also lower in children than in adults. Data presented here indicate the possibility of a relationship between low levels of bactericidal activity toward S. Typhi in serum and susceptibility to disease, as observed for other polysaccharide-encapsulated bacteria. Bactericidal antibody may be a marker of protective immunity against S. Typhi.
