ABSTRACT
COVID-19 requires unprecedented mobilization of the health systems to prevent the rapid spread of this unique virus, which spreads via respiratory droplet and causes respiratory disease. There is an urgent need for an accurate and rapid test method to quickly identify many infected patients and asymptomatic carriers to prevent virus transmission and assure timely treatment of the patients. This article aims as an outcome of review of the evidence on viral load and its virulence of SARS-CoV2,so that it will help in further understanding the fact useful for investigating and managing the COVID-19 cases. A search of available evidence was conducted in pub-med "COVID-19 viral load and virulence" and its associated characters world-wide and Google Scholar to capture the most recently published articles. The WHO and Centre for Disease Control and Prevention (CDC) database of publications on novel coronavirus were also screened for relevant publications. s of 55 articles were screened by two authors and 15 were included in this study based on the inclusion criteria. SARS-coV2, the causative agent of COVID-19 falls under the coronavirus family but it has higher infectivity compared to SARS and MERS with higher reproduction numbers(Ro). Virulence has been found to be different throughout the world,however lower compared to SARS and MERS,till date. The most common clinical features have been found to be cough and fever. RT - PCR remains the most sensitive and specific method for the diagnosis of COVID-19 although it is time consuming, costly and requires highly skilled human resources. Hence, newer modalities like RT-LAMP can be alternative for point of care diagnosis as this is both cost effective and requires less skilled human resources. Despite recent advances in disease diagnosis and treatment outcomes using latest technological advances in molecular biology, the global pandemic COVID-19 remains a major headache for governments across the world due to limited testing capacity and lack of appropriate treatment and vaccine.

ABSTRACT
COVID-19 first time appeared in December 2019 in Wuhan, China. The number of cases increased rapidly in china and outside and the World Health Organization declared a pandemic on 11th March 2020. The pregnant and postpartum women, child, and neonatal populations are vulnerable to this disease due to immunological and physiological changes. This paper analyzed the published evidence for assessing the effect of COVID-19 on neonatal health and health care. Online published literature was searched from PubMed, Google Scholar, and other official webpages using keywords: "coronavirus/COVID-19/new coronavirus 2019"/SARS-CoV-2 and neonatal health/care/outcomes" and reviewed to prepare this article. COVID-19 is the potential to transmit either mother to fetus or mother/caregiver to neonates. However, neonates born from infected mothers did not show significant clinical features. Pharyngeal-swab, amniotic-fluid, cord-blood, and breast-milk test results were not found positive. Health facility-based vaginal/caesarian delivery was considered a low risk of transmission. However, recommended to separate neonates with infected mothers/caregivers and test immediately after birth to avoid the possible transmission. Mothers/caregivers should take routine preventive measures such as washing hands frequently and avoiding contact with infected people. If neonates suffered from the server acute respiratory distress requires intensive care urgently. Despite the possibility of the intrauterine transmission of COVID-19 direct evidence is still lacking so it needs more studies for further confirmation. The International Pediatric Association suggested preventive programs, curative care, vaccination, and telemedicine care as the minimum services and called on its members to address these cares during the pandemic.

ABSTRACT
Novel coronavirus (SARS-CoV-2) is a new strain of coronavirus causing COVID-19, first identified in Wuhan City, China towards the end of 2019. At present, there is no evidence that pregnant women are more likely to be severely ill, need ICU care, or die from the illness in comparison to non-pregnant adults. Evidences suggest that vertical transmission, might be possible. We searched and retrieved the published literature from PubMed and Google Scholar using various keywords. We further searched the official webpages of various organizations for the updated information. Pregnant individuals in particular are encouraged to take all available precautions to optimize health and avoid exposure to COVID-19. Adequate Testing should be prioritized in pregnant women admitted with suspected COVID-19. When a pregnancy is complicated by critical illness, the pregnant patient should ideally be cared for at a Level III or IV hospital. In the face of COVID-19, antenatal fetal surveillance and ultrasonography should continue as medically indicated when possible and elective ultrasound examinations should not be performed. Maternal immunizations continue to be an essential component of prenatal care and Ob-gyns should screen all pregnant individuals for mental health issues. Although the most commonly reported sign in COVID-19 is fever, nevertheless, other causes of intrapartum fever should not be overlooked. Cesarean delivery should be based on obstetric indications and not COVID-19 status alone. Infants born to patients with known COVID-19 should be considered infants with suspected COVID-19. The suspected or confirmed COVID-19 mother and infant can be allowed to remain together with enhanced precautions and suspected or confirmed maternal COVID-19 is not a contraindication to breastfeeding. If both the mother and the infant are healthy, it may be prudent to expedite discharge, so as to limit the risk of inadvertent exposure and infection. The Ob-gyns should commit to providing necessary care, although modifications to health care delivery approaches may be necessary. Copyright © 2020, Kathmandu University. All rights reserved.
ABSTRACT
COVID-19 has significantly impacted the world and Nepal is no exception. The pandemic has caused a reduction in health service delivery, especially for women's health conditions, resulting in an increase in challenges for an already vulnerable group. Maternity care, reproductive health services, preventive interventions, nutritional advice and mental health care are not being addressed and with an increase in domestic violence, the health and wellbeing of women in Nepal is precarious and needs to be addressed immediately.

ABSTRACT
The consequences of the COVID-19 pandemic are extensive and far-reaching. Non COVID communicable diseases continue to spread and non-communicable diseases continue to progress. People may access healthcare facilities little bit late due to fear of contracting COVID-19 and present with severe symptoms, even with complications. Nepal has been facing dual burden of both non-communicable and communicable diseases. The number of COVID-19 patients has continuously been rising in Nepal since the start of May 2020. There is an anticipated surge of infectious disease such as malaria, dengue fever, enteric fever, scrub typhus, leptospirosis during summer and monsoon seasons in Nepal. There will be surge of cases of acute undifferentiated febrile illness (AUFI) during monsoon. As fever is one of the very common symptoms of COVID-19, so COVID-19 needs to be considered in differential diagnoses of acute undifferentiated febrile illness.

ABSTRACT
Since first cluster of unknown pneumonia from China reported in December 2019 to World Health Organization, more than 10.5 million new cases and more than 0.513 million deaths have been reported till June 30, 2020 in six months' time. World got to know lot of facts about COVID-19 within short period of six months and success stories too concerning its containment. The situation has constantly been unfolding every moment educating people regarding public health and clinical aspects of the infection and disease and its impact on countries and communities. But still lot of information and evidences are required with regard to pharmacological interventions including effective drugs and efficacious vaccine to mitigate the impact of COVID-19 pandemic at all levels. It seems that we have to live with COVID-19 months-years as the virus is going to stay for longer period of time. The option is to continue practice of effective non-pharmacological interventions as to minimize spread of COVID-19 and ensure adequate provision of PPE to healthcare workforce and testing of health-care workers (HCWs) as to alleviate the anxiety of HCW and lessen their depletion by unnecessary quarantine thereby protect their health and reduce in hospital transmission.

ABSTRACT
Booster vaccine doses are meant to revive the fading immunity created by prior exposure to an immunizing antigen. They stabilize the antibody response ultimately leading to longer and higher protection against pathogens. Immunological studies done for COVID-19 vaccines have documented a steady decrease in antibody levels among vaccinated individuals and evidence of breakthrough infections over a course of time. With an emerging science behind the need for COVID-19 vaccine booster shots, there equally is a contrasting idea regarding its absolute necessity. Copyright © 2021, Kathmandu University.

ABSTRACT
Objective The objective of this study was to assess the ongoing pharmacovigilance of coronavirus disease-19 (COVID-19) vaccines in the Nepalese context based on the available preliminary adverse drug reaction (ADR) reports and suggest approaches for strengthening pharmacovigilance mechanisms. Methods Currently, many COVID-19 vaccines are under advanced development and some have begun to be administered. In Nepal, the vaccination programme was initiated with Oxford/AstraZeneca COVID-19 AZD1222 (Covishield) vaccine on January 27th targeting frontline healthcare professionals, sanitary staff and security workers. Newspaper reports and ADR reports received at a regional pharmacovigilance centre in Nepal were analysed. Nepal initiated a national pharmacovigilance programme 15 years back and has 14 functioning regional pharmacovigilance centres. The authors examine the strengths and challenges facing the current pharmacovigilance system in ensuring the safety of COVID-19 vaccines. Key findings The news coverage has not mentioned any deaths till date with COVID-19 vaccination. Some patients reported vomiting, urticaria and sudden increase in blood pressure. Few people suffered from headache, fever and myalgia after being vaccinated. A vaccine, approved in an accelerated manner may have safety concerns. The vaccine may cause several types of reactions, but serious reactions have not been reported. Occurrence of adverse effects due to the vaccine is being studied. Conclusions Involving key stake holders, training health professionals and strengthening existing reporting procedures are important. Developing a system of reporting and analysing ADRs daily can help generate actionable intelligence to improve the safety of the vaccination programme. Establishing functioning communication channels between regulatory authorities and other stakeholders is crucial.
