Many viruses require reduced sulfhydryl groups for cell fusion and entry. Corona viruses, including SARS-CoV-2 (the cause of the condition now named coronavirus disease 2019 or COVID-19), are rich in cysteine, which residues must be intact for viral activity. Sulfhydryl groups are vulnerable to oxidation. Ozone therapy, a very inexpensive and safe modality may safely exploit this critical vulnerability in many viruses, inclusive of SARS-CoV-2.

An outbreak of novel coronavirus disease (COVID-19) in China has influenced every aspect of life. Healthcare professionals, especially dentists, are exposed to a higher risk of getting infected due to close contact with infected patients. The current study was conducted to assess anxiety and fear of getting infected among dentists while working during the current novel coronavirus diseases (COVID-19) outbreak. In addition, dentists’ knowledge about various practice modifications to combat COVID-19 has been evaluated. A cross-sectional study was conducted using an online survey from 10th to 17th March 2020. The well-constructed questionnaire was designed and registered at online website (Kwiksurveys) and validated. A total of 669 participants from 30 different countries across the world responded. After scrutiny, completed questionnaires (n = 650) were included in the study. Statistical analysis was performed using SPSS version 25. Chi-Square and Spearman correlation tests were applied to control confounders and assess the relation of dentists’ response with respect to gender and educational level. More than two-thirds of the general dental practitioners (78%) from 30 countries questioned were anxious and scared by the devastating effects of COVID-19. A large number of dentists (90%) were aware of recent changes in the treatment protocols. However, execution of amended treatment protocol was recorded as 61%. The majority of the dentists (76%) were working in the hospital setting out of which 74% were from private, and 20% were from government setups. Individually we received a large number of responses from Pakistan and Saudi Arabia, but collectively more than 50% of the responses were from other parts of the world. Despite having a high standard of knowledge and practice, dental practitioners around the globe are in a state of anxiety and fear while working in their respective fields due to the COVID-19 pandemic impact on humanity. A number of dental practices have either modified their services according to the recommended guidelines to emergency treatment only or closed down practices for an uncertain period.

To determine distribution of severe acute respiratory syndrome coronavirus 2 in hospital wards in Wuhan, China, we tested air and surface samples. Contamination was greater in intensive care units than general wards. Virus was widely distributed on floors, computer mice, trash cans, and sickbed handrails and was detected in air ≈4 m from patients.

Since 2003, outbreaks of Coronavirus have caused multiple public health epidemics including severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The first case of infection in response to a new strain of Coronaviridae, designated Coronavirus disease-19 (COVID-19) was recorded in Wuhan, China [1]. This virus appears to be weaker than SARS, in terms of pathogenesis but more sustained in its transmission behavior [2]. COVID-19 is transmittedthrough droplet inhalation, saliva, nasal and mucous membranes of eyes. Symptoms include fever, continuous coughing and shortness of breath.

In late December of 2019, a new coronavirus was discovered in China. On 11 February 2020, the World Health Organization named the disease caused by this virus COVID-19. The disease quickly spread to Chinese cities and other parts of the world, including Thailand, Japan, Taiwan and Iran.1 The number of infected patients increased daily until the World Health Organization in June declared the outbreak a serious and urgent threat to public health. Most people infected with the virus recover well, but some also may experience fatal complications, such as acute organ failure, septic shock, acute pulmonary edema, acute pneumonia, and acute respiratory distress syndrome.1 As infection has been transmitted from individual to individual,2 the first cases of the disease in areas outside of Wuhan, occurred in travelers from Wuhan; as The First Case of COVID-19 was confirmed to be a 35-year-old woman living in Wuhan who traveled to Korea.3 On January 20, 2020, a 55-year-old woman working in Wuhan, arrived at Taiwan and was referred to quarantine authorities with symptoms of sore throat, dry cough, fatigue, and feeling low-grade fever on January 11.4 While COVID-19 infection seems to be more prevalent in adults than in children, rare cases of children infection are being reported, mainly seen in family clusters.5 The presented case is a 75-day-old infant that was referred to the pediatric emergency department, with a history of severe dry cough and abnormal noisy breathing sound (heard without a stethoscope) during the last 11 days.

Background: Since December 2019, when coronavirus disease 2019 (Covid-19) emerged in Wuhan city and rapidly spread throughout China, data have been needed on the clinical characteristics of the affected patients.

Methods: We extracted data regarding 1099 patients with laboratory-confirmed Covid-19 from 552 hospitals in 30 provinces, autonomous regions, and municipalities in mainland China through January 29, 2020. The primary composite end point was admission to an intensive care unit (ICU), the use of mechanical ventilation, or death.

Results: The median age of the patients was 47 years; 41.9% of the patients were female. The primary composite end point occurred in 67 patients (6.1%), including 5.0% who were admitted to the ICU, 2.3% who underwent invasive mechanical ventilation, and 1.4% who died. Only 1.9% of the patients had a history of direct contact with wildlife. Among nonresidents of Wuhan, 72.3% had contact with residents of Wuhan, including 31.3% who had visited the city. The most common symptoms were fever (43.8% on admission and 88.7% during hospitalization) and cough (67.8%). Diarrhea was uncommon (3.8%). The median incubation period was 4 days (interquartile range, 2 to 7). On admission, ground-glass opacity was the most common radiologic finding on chest computed tomography (CT) (56.4%). No radiographic or CT abnormality was found in 157 of 877 patients (17.9%) with nonsevere disease and in 5 of 173 patients (2.9%) with severe disease. Lymphocytopenia was present in 83.2% of the patients on admission.

Conclusions: During the first 2 months of the current outbreak, Covid-19 spread rapidly throughout China and caused varying degrees of illness. Patients often presented without fever, and many did not have abnormal radiologic findings. (Funded by the National Health Commission of China and others.).

Health services across the world face an unprecedented situation as a result of a global COVID-19 outbreak. Urgent joined research efforts regarding the SARS-COV-2 rapid tests, accurate diagnosis, especially early recognition, and effective treatment of life-threatening complications would be highly desirable for humanity and medical workforce all over the world that try to combat a current global pandemic threat. Due to indirect complex effect, intensified COVID-19 therapies and multi-drug treatment, it is believed that some oral conditions could be aggravated by COVID-19 disease, particularly those with autoimmune aetiology, linked to compromised immune system or long-term pharmacotherapy
