The virus responsible for the COVID-19 pandemic is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which belongs to the genus Betacoronavirus. This genus also includes the severe acute respiratory syndrome coronavirus (SARS-CoV) and the Middle East respiratory syndrome coronavirus (MERS-CoV). The common symptoms of COVID-19 infection are fever and respiratory symptoms, but it can also involve the gastrointestinal tract (GIT), resulting in manifestations such as diarrhea, nausea and/or vomiting and abdominal pain. The emergence of COVID-19 led to public health emphasis on droplet transmission and precautions of contact with respiratory secretions. However, mounting evidence demonstrates detection of SARS-CoV-2 RNA in stool samples of COVID-19 patients. It has also been demonstrated that the host receptor angiotensin-converting-enzyme-2 (ACE-2) is highly expressed not just in respiratory cells but also in gastrointestinal sites involving the glandular cells of gastric, duodenal, and rectal epithelium. This suggests that SARS-CoV-2 can infect the digestive system, serving as another route of transmission. This review aims to study the prevalence of some of the gastrointestinal manifestations following COVID-19 infection and findings of positive SARS-CoV-2 RNA in stool specimens while making parallels to the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) infection. We will also discuss the possible pathophysiology of COVID-19 related gastrointestinal involvement.

Coronaviruses belong to a large family of viruses that can cause disease outbreaks ranging from the common cold to acute respiratory syndrome. Since 2003, three zoonotic members of this family evolved to cross species barriers infecting humans and resulting in relatively high case fatality rates (CFR). Compared to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV, CFR = 10%) and pandemic Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2, CFR = 6%), the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has scored the highest CFR (approximately 35%). In this review, we systematically summarize the current state of scientific knowledge about MERS-CoV, including virology and origin, epidemiology, zoonotic mode of transmission, and potential therapeutic or prophylactic intervention modalities.

Coronaviruses are a large family of RNA viruses which cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS), Severe Acute Respiratory Syndrome (SARS) and COVID-19. This article highlights some key findings based on a thorough scanning of genes of 475 SARS-CoV2 genomes, including the co-presence of ORF7a and ORF8 over the 256 SARS-CoV2 genomes and the absence of the gene ORF7b over the 219 SARS-CoV2 genomes collected from various countries including India. The presence of the gene ORF7b is found in the SARS-CoV2 genomes containing the L-type strain which is reported to having much higher virulence as compared to the S-type strain.

Coronaviruses are a big identified group of viruses that could result in sickness in humans and animals. It was confirmed that many of these viruses caused respiratory diseases among humans and their symptoms range from popular colds to more serious diseases, such as the Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). The recently detected Coronavirus (called SARS-CoV-2) causes the COVID-19 pandemic, which causes a serious threat worldwide. There was no previous knowledge of this virus before the outbreak of Wuhan city in China in December 2019.  However, there is progress in defining, understanding and dealing with this virus.  In this review, we are focusing on the common questions regarding coronavirus transition and spread, and how to prevent the infection.

The disaster due to the novel coronavirus disease 2019 (COVID-19) around the world has made investigators enthusiastic about working on different aspects of COVID-19. However, although the pandemic of COVID-19 has not yet ended, it seems that COVID-19 compared to the other coronavirus infections (the Middle East Respiratory Syndrome [MERS] and Severe Acute Respiratory Syndrome [SARS]) is more likely to target the heart. Comparing the previous presentations of the coronavirus family and the recent cardiovascular manifestations of COVID-19 can also help in predicting possible future challenges and taking measures to tackle these issues.

Coronavirus merupakan keluarga besar virus yang menyebabkan penyakit pada manusia, biasanya menyebabkan penyakit infeksi saluran pernapasan, mulai flu biasa hingga penyakit yang serius seperti Middle East Respiratory Syndrome (MERS) dan Sindrom Pernafasan Akut Berat/ Severe Acute Respiratory Syndrome (SARS). Coronavirus jenis baru yang ditemukan pada manusia sejak kejadian luar biasa muncul di Wuhan Cina, pada Desember 2019, kemudian diberi nama Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV2), dan menyebabkan penyakit Coronavirus Disease-2019 (COVID-19). Salah satu cara gampang melakukan pencegahan terhadap penyebaran virus ini adalah dengan menggunakan Handsanitizer alami. Menurut Organisasi Kesehatan Dunia (WHO), Handsanitizer alami harus mengandung setidaknya 60% alkohol untuk bekerja secara efektif. Selain handsanitizer, dengan melalukan metode penyemprotan disenfektan menggunakan cairan disenfektan. Disenfektan merupakan bahan kimia yang berguna untuk mencegah pertumbuhan bakteri ataupun jasad renik pada permukaan benda mati. Pelaksanaan pengabdian kepada masyarakat mengadakan penyaluran handsanitizer dan sabun cuci tangan alami serta penyemprotan disenfektan di desa Ngale sebagai upaya pencegahan Covid-19. Metode dalam pelaksanaan kegiatan ini yaitu wawancara dan diskusi bersama kepala desa Ngale. Kegiatan ini diharapkan mampu menumbuhkan kesadaran pada masyarakat akan pentingnya menjaga kebersihan, salah satunya menjaga kebersihan tangan serta dapat memutus mata rantai penyebaran Covid-19 di desa Ngale Kec Pilangkenceng Kab Madiun.

  Since the Coronavirus disease 2019 (COVID-19) pandemic unfolded in China (Huang et al., 2020) back in December 2019, thus far, more than five million people were infected with the virus and 333,401 death were recorded worldwide (WHO, 2020b). The exponential increase in number shows that COVID-19 spreads faster compared to Severe Acute Respiratory Syndrome (SARS) or Middle East Respiratory Syndrome (MERS). A study (Zou et al., 2020) has shown that high viral loads of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are detected in symptomatic patients soon after the onset of symptoms, wherein the load content is higher in their nose than in their throat. Furthermore, the same study has revealed similar viral loads between symptomatic and asymptomatic patients. Therefore, these findings may suggest the possibility of COVID-19 transmission earlier before the onset of symptoms itself. In the early stages of the pandemic, the control measures carried out have focused on screening of symptomatic person; at the time, the whole world thought that the spread of SARS-Cov-2 would only occur through symptomatic person-to-person transmission. In comparison, transmission in SARS would happen after the onset of illness, whereby the viral loads in the respiratory tract peaked around ten days after the development of symptoms by patients (Peiris et al., 2003). However, case detection for SARS (i.e. screening of symptomatic persons) will be grossly inadequate for the current COVID-19 pandemic, thus requiring different strategies to detect those infected with SARS-CoV-2 before they develop the symptoms.

Coronaviruses (CoVs) are a group of viral pathogens that infect mammals and birds. The presentation in humans is typically that of a mild upper respiratory tract infection, similar to the common cold. However, in recent years, dramatic attention has arisen for more lethal members of this viral family (e.g., severe acute respiratory syndrome [SARS-CoV], Middle East respiratory syndrome [MERS-CoV], and coronavirus disease 2019 [COVID-19]). The epidemiology, clinical presentation, diagnosis, and management of these viruses are discussed in this review. Importantly, new guideline tables from the Centers for Disease Control and Prevention, as well as the World Health Organization are provided at the conclusion of the review. This review contains 12 tables, 3 figure and 48 references. Keywords: Coronavirus, severe acute respiratory distress syndrome (SARS), Middle East respiratory syndrome (MERS), COVID-19, respiratory infection, antiviral, real-time polymerase chain reaction
