“…Dust generated during the hatch in commercial hatcheries has also been implicated in pathogen cross contamination to other areas of the hatchery such as the exhaust ducts, chick room, egg room, etc (Cason et al, 1994;Bailey et al, 1996). Negative air ionization has been shown to be effective for reducing viral transmission of newcastle diseases virus between 27 and 100% (Estola et al, 1979;Mitchell and King, 1994). This indicates that negative ions inside the poultry are attached to the aerosol particles and larger aerosol particles are produced from the smaller aerosol particles (Gabbay, 1990).…”

The air ions are continuously generated and destroyed by various processes in the atmosphere. Near the surface, the nature of ions is very complex and they show large variations in their physical properties. The attachment of small ions to the aerosol particles is depending on the mobility of air ions. High mobility air ions immediately are attached to the aerosol particles and settle down on the surface. In this study we report, about the air ion variation at different sites like Rural, Coastal, Mountain, Poultry farm and urban in the state of Maharashtra in India. The aim of this study is to understand the plausible distribution of air ions both diurnally and at different times in a day for long time (three years) and with various meteorological variables. The preliminary analysis of the data has reveled that negative air ions are observed to have attached to the aerosol particles and large aerosol particles are formed from small aerosol particles. Therefore uni-polarity factor observed to be below unity for coastal, mountain and rural site and about 2.8 at an urban site. However worst case is observed at the Poultry farm, where uni-polarity factor is 6.3, which is very harmful for human health. There is also effect of meteorological parameters on air ion concentration in the atmosphere.

“…Ozone gas has been shown to inactivate norovirus and may be used in empty rooms to decontaminate surfaces, however in rooms with patients ozone should not been used due to its toxicity 21 . Generation of negative ions has previously been shown to reduce transmission of Newcastle disease virus 22 23 and several kind of bacteria 24 25 in animal experimental set-ups.…”

By the use of a modified ionizer device we describe effective prevention of airborne transmitted influenza A (strain Panama 99) virus infection between animals and inactivation of virus (>97%). Active ionizer prevented 100% (4/4) of guinea pigs from infection. Moreover, the device effectively captured airborne transmitted calicivirus, rotavirus and influenza virus, with recovery rates up to 21% after 40 min in a 19 m3 room. The ionizer generates negative ions, rendering airborne particles/aerosol droplets negatively charged and electrostatically attracts them to a positively charged collector plate. Trapped viruses are then identified by reverse transcription quantitative real-time PCR. The device enables unique possibilities for rapid and simple removal of virus from air and offers possibilities to simultaneously identify and prevent airborne transmission of viruses.

“…Reduced infectivity has been proposed to be due to reactive oxygen species and ozone, through lipid-and protein peroxidation reactions that may cause damage and destruction to the viral lipid envelope and protein capsid. Along with the virus breakage if the immunity is raised with immune-modulators of phyto extracts [38] and anti-influenza drugs which can kill the virus infection [39] .…”

Background:Covid-19 is a new born sibling of the influenza family of SARS-CoV-2, named on February 11, as a new type of corona virus by the WHO. Covid-19 indicates its close relationship with activity and approaches with the SARS virus, which further triggered as epidemic in 2003 and 2004 and now similar lung triggered by SARS-CoV-2 is called Covid-19 (Corona Virus Disease 2019). Methods: A combination of integrative therapies were administered to a 27 year old female positive with unknown SARS-CoV identified as COVID-19 with a query of coronavirus contaminated from travel history and a student of Wuhan with a respiratory congestion, integrative approach of non-invasive (ion therapy) and non-drug therapy, quantitative analysis by real time PCR, vital signs were recorded beforeand after the treatment, as all the vitals were normal and real time PCR results were monitored. Results: The integrative therapy with isolation for 29 days from 31 st January to 27 th February was found to be satisfactory and the report, which has Real time PCR values detecting Covid-19 positive on 29 th January 2020 gave a negative result,it showed not detected and less than 35 Ct for the test. Conclusion: The integrative approach showed that it has high potential in treatment of Covid-19and can further imbibed in republic of china as well as other places where in 136 volunteers are part of the study and this could be an adjuvant therapy with a integrative approach for Covid-19 treatments.
