The current COVID-19 pandemic needs unconventional therapies to tackle the resulted high morbidity and mortality. Convalescent plasma is one of the therapeutic approaches that might be of benefit. Forty nine early-stage critically-ill COVID-19 patients residing in Respiratory Care Units (RCU) of three hospitals in Baghdad, Iraq, were included: 21 received convalescent plasma while 28, namely control group, did not receive it. ⋯ In addition, all the patients who were given convalescent plasma showed high levels of SARS-CoV-2 IgG and IgM three days after plasma transfusion. Plasma from donors with high levels of SARS-CoV-2 IgG and donors with positive SRAS-CoV-2 IgM showed better therapeutic results than other donors. Convalescent plasma therapy is an effective therapy if donors with high level of SARS-Cov2 antibodies are selected and if recipients are at their early stage of critical illness, being no more than three days in RCUs.

Review Comparative Study
SARS-CoV-2, SARS-CoV, and MERS-COV: A comparative overview
The recent outbreak of SARS-CoV-2 that started in Wuhan, China, has now spread to several other countries and is in its exponential phase of spread. Although less pathogenic than SARS-CoV, it has taken several lives and taken down the economies of many countries. Before this outbreak, the most recent coronavirus outbreaks were the SARS-CoV and the MERS-CoV outbreaks that happened in China and Saudi Arabia, respectively. ⋯ Studies reveal that SARS-CoV-2 is very similar in structure and pathogenicity with SARS-CoV, but the most important structural protein, i.e., the spike protein (S), is slightly different in these viruses. The presence of a furin-like cleavage site in SARS-CoV-2 facilitates the S protein priming and might increase the efficiency of the spread of SARS-CoV-2 as compared to other beta coronaviruses. So, furin inhibitors can be targeted as potential drug therapies for SARS-CoV.

The Personal Protective Equipment (PPE) is essential to avoid the COVID-19 spread to health care workers. Its use can be difficult, posing a high risk of contamination, mainly during doffing, then with the risk of becoming infected. ⋯ The PPE donning and doffing is critical and may be changed significantly by active training. In responding to the current COVID-19 pandemic in 2020, activities of training in donning and doffing PPE would provide a means of training personnel, reducing the cognitive load and maybe the risk of contamination and infection of health care workers.

The recent outbreak of coronavirus disease 2019 (COVID-19), is now officially declared as a pandemic by the World Health Organization. As of now, there is no known effective pharmaceutical agent against the SARS-CoV-2 virus. ⋯ More recent studies have highlighted the possibility of treating patients infected with the novel SARS-CoV-2 virus with chloroquine and hydroxychloroquine, of which mechanism of action is not completely understood. We seek to draw the attention of the scientific community to the possibility of drastically reducing the effects of the virus on the affected patients and improving clinical trials outcome through the synergistic action of zinc and chloroquine in patients suffering from the coronavirus disease.
