Effectiveness of Disinfection with Chlorine Dioxide on Respiratory Transmitted, Enteric, and Bloodborne Viruses: A Narrative Synthesis
Effectiveness of Disinfection with Chlorine Dioxide on Respiratory Transmitted, Enteric, and Bloodborne Viruses: A Narrative Synthesis
A viral spread occurrence such as the SARS-CoV-2 pandemic has prompted the evaluation of different disinfectants suitable for a wide range of environmental matrices. Chlorine dioxide (ClO2) represents one of the most-used virucidal agents in different settings effective against both enveloped and nonenveloped viruses. This narrative synthesis is focused on the effectiveness of ClO2 applied in healthcare and community settings in order to eliminate respiratory transmitted, enteric, and bloodborne viruses. Influenza viruses were reduced by 99.9% by 0.5–1.0 mg/L of ClO2 in less than 5 min. Higher concentration (20 mg/L) eliminated SARS-CoV-2 from sewage. ClO2 concentrations from 0.2 to 1.0 mg/L ensured at least a 99% viral reduction of AD40, HAV, Coxsackie B5 virus, and other enteric viruses in less than 30 min. Considering bloodborne viruses, 30 mg/L of ClO2 can eliminate them in 5 min. Bloodborne viruses (HIV-1, HCV, and HBV) may be completely eliminated from medical devices and human fluids after a treatment with 30 mg/L of ClO2 for 30 min. In conclusion, ClO2 is a versatile virucidal agent suitable for different environmental matrices.

Ayushman Bharat PM-JAY provides free health cover up to Rs. 5 lakh per year per family. The scheme was launched with 10.74 crore beneficiary families. However, 33 states/UTs have increased the beneficiary base to 13.44 families. Beneficiaries of Ayushman Bharat PM-JAY can avail free treatment of post-Covid related complications including Mucormycosis, Black Fungus etc. under the scheme. States are also being supported in terms of allocation and supply of Amphotericin B. Amphotericin B is being provided at an affordable price under the Pradhan Mantri Bhartiya Janaushadhi Pariyojna (PMBJP)."

Airborne transmission of respiratory viruses
Airborne transmission of respiratory viruses
The COVID-19 pandemic has highlighted controversies and unknowns about how respiratory pathogens spread between hosts. Traditionally, it was thought that respiratory pathogens spread between people through large droplets produced in coughs and through contact with contaminated surfaces (fomites). However, several respiratory pathogens are known to spread through small respiratory aerosols, which can float and travel in air flows, infecting people who inhale them at short and long distances from the infected person. Wang et al. review recent advances in understanding airborne transmission gained from studying the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and other respiratory pathogens. The authors suggest that airborne transmission may be the dominant form of transmission for several respiratory pathogens, including SARS-CoV-2, and that further understanding of the mechanisms underlying infection from the airborne route will better inform mitigation measures. Science , abd9149, this issue p. [eabd9149][1] ### BACKGROUND Exposure to droplets produced in the coughs and sneezes of infected individuals or contact with droplet-contaminated surfaces (fomites) have been widely perceived as the dominant transmission modes for respiratory pathogens. Airborne transmission is traditionally defined as involving the inhalation of infectious aerosols or “droplet nuclei” smaller than 5 μm and mainly at a distance of >1 to 2 m away from the infected individual, and such transmission has been thought to be relevant only for “unusual” diseases. However, there is robust evidence supporting the airborne transmission of many respiratory viruses, including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS)–CoV, influenza virus, human rhinovirus, and respiratory syncytial virus (RSV). The limitations of traditional views of droplet, fomite, and airborne transmission were illuminated during the COVID-19 pandemic. Droplet and fomite transmission of SARS-CoV-2 alone cannot account for the numerous superspreading events and differences in transmission between indoor and outdoor environments observed during the COVID-19 pandemic. Controversy surrounding how COVID-19 is transmitted and what interventions are needed to control the pandemic has revealed a critical need to better understand the airborne transmission pathway of respiratory viruses, which will allow for better-informed strategies to mitigate the transmission of respiratory infections. ### ADVANCES Respiratory droplets and aerosols can be generated by various expiratory activities. Advances in aerosol measurement techniques, such as aerodynamic and scanning mobility particle sizing, have shown that the majority of exhaled aerosols are smaller than 5 μm, and a large fraction are

'“I had a 43-year-old patient with no comorbidities and perfect dental hygiene who came with mucormycosis. When we checked his sugar levels, it was over the roof. The thing is, most COVID-19 patients are unaware about the spike in their blood sugar levels,” Dr Veerabahu adds. " "With some patients with severely affected lungs due to COVID-19 triggered cytokine storms, the Amphotericin B injection can have a serious impact" "it is important to maintain oral hygiene by brushing frequently, wearing fresh masks, etc."

Misleading Math: Kill Claims and Log Reduction
Bacteria grow logarithmically/ exponentially, therefore a logarithmic reduction measurement is needed.. Logarithmic reduction is pervasive in the cleaning and disinfection literature, but many do not appreciate what it actually describes. The EPA guidelines on disinfection state that a greater than or equal to 6-fold logarithmic (≥6log) reduction in less than 10 minutes is needed to claim disinfection. When a hospital is evaluating disinfecting technologies it
