Verdict: Neutral
Claim: chloroquine and hydroxychloroquine (HCQ), which have been extensively used for the treatment of malaria with known safety and efficacy, also limit acidification of endosomes, Golgi vesicles, and lysosomes. These molecules significantly reduce SARS-CoV and SARS-CoV-2 infection in vitro.
Question: are there any drugs that work for SARS-CoV or SARS-CoV-2 in animals?
Evidence: We show that a high (5106 pfu) and medium (5104 pfu) dose of SARS-CoV-2 induces consistent upper respiratory tract (URT) viral RNA shedding in both groups of six challenged animals, whilst a low dose (5102 pfu) resulted in only one of six displaying signs of URT viral RNA replication.  
Verdict: Neutral
Claim: Yes, the novel coronavirus can survive on surfaces. No, it doesn't seem to matter.
Question: touching a contaminated surface will not make you sick
Evidence: Inefficient human-to-human transmission of zoonotic strains may initially limit the spread of transmission, but an infection may be contracted by touching contaminated surfaces.
Verdict: Refutes
Claim: A lot has been written around the novel Coronavirus and how it impacts lungs, but in recent few months, experts have observed a rise in cardiac arrest cases during the pandemic.
Question: are heart complications likely in patients with COVID-19?
Evidence: Cardiovascular complications were mainly observed in the confirmed COVID-19+group, consisting of heart failure (9%), palpitations/arrhythmias (3%), stroke/TIA (3%) and pulmonary hypertension (3%). Cardiovascular symptoms such as chest pain (1%), myocardial injury (1%) and pericardial effusion (1%) were also recorded.
Verdict: Supports
Claim: Vitamin C may help shorten the duration and severity of colds caused by other viruses, but this is no guarantee that it will have the same effect on the coronavirus that causes COVID-19.
Question: Does Vitamin D impact COVID-19 prevention and treatment?
Evidence: Several studies demonstrated the role of vitamin D in reducing the risk of acute viral respiratory tract infections and pneumonia. These include direct inhibition with viral replication or with anti-inflammatory or immunomodulatory ways. In the meta-analysis, vitamin D supplementation has been shown as safe and effective against acute respiratory tract infections. Thus, people who are at higher risk of vitamin D deficiency during this global pandemic should consider taking vitamin D supplements to maintain the circulating 25(OH)D in the optimal levels (75-125nmol/L).
Verdict: Neutral
Claim: Blood pressure drugs linked to lower Covid-19 mortality
Question: what kinds of complications related to COVID-19 are associated with hypertension?
Evidence:  Hypertension has been proven to be more prevalent in patients with an adverse outcome (admission in intensive care unit, use of mechanical ventilation, or death).
Verdict: Neutral
Claim: By curbing inflammation, the drug could help people whose immune systems have become overactive through a process called a cytokine storm, which can cause severe COVID-19 symptoms
Question: will SARS-CoV2 infected people develop immunity?
Evidence: The CD4 + memory exploiting could help immune system to recall immunity of already know antigens against coronaviruses, avoiding or limiting "lung crash" until virus specific immunity develops and making it faster and prolonged. Finally, this administration could be helpful not only in already infected patients, but also before infection. In fact, people could have an immune system more ready when the contact with the Covid-19 will occur.
Verdict: Neutral
Claim: I think it is not really far from the truth to say that you can use extracts of ginger, garlic and many other medicinal plants to take care of the associated symptoms of viral infections, including COVID-19. 
Question: Does garlic protect against covid-19
Evidence: compounds derived from Allium sativum (garlic) have the potential to decrease the expression of proinflammatory cytokines and to reverse the immunological abnormalities to more acceptable levels. Allium sativum is suggested as a beneficial preventive measure before being infected with SARS-CoV-2 virus.
Verdict: Supports
Claim: Yes, kids can get COVID-19
Question: Can children get COVID-19?
Evidence: Between 1st March and 15th May 2020, 166 children (<18 years of age) presented to a specialist childrens hospital with clinical features of possible COVID-19 infection. 65 patients (39.2%) tested positive for SARS-CoV-2 virus. 
Verdict: Supports
Claim: wear cloth face coverings in public can stop spreading coronanvirus when social distancing is difficult. This advice is based on evidence that people with COVID-19 can transmit the COVID-19 virus before they realize they have it.
Question: Can face masks protect me from the coronavirus disease?
Evidence: We find that the critical mask adherence is 5 per 100 when 80% wear face masks.
Verdict: Supports
Claim: not all masks confer equal levels of protection
Question: what are the best masks for preventing infection by Covid-19?
Evidence: However, low quality evidence suggests that N95 respirators protect HCWs from clinical respiratory infections.
Verdict: Neutral
Claim: A central player in the fight against the novel coronavirus is our immune system.
Question: will SARS-CoV2 infected people develop immunity?
Evidence: The CD4 + memory exploiting could help immune system to recall immunity of already know antigens against coronaviruses, avoiding or limiting "lung crash" until virus specific immunity develops and making it faster and prolonged. Finally, this administration could be helpful not only in already infected patients, but also before infection. In fact, people could have an immune system more ready when the contact with the Covid-19 will occur.
Verdict: Neutral
Claim: Cell that Ab8 is highly effective in preventing and treating SARS-CoV-2 infection in mice and hamsters. Its tiny size not only increases its potential for diffusion in tissues to better neutralize the virus, but also makes it possible to administer the drug by alternative routes, including inhalation. Importantly, it does not bind to human cells -- a good sign that it won't have negative side-effects in people.
Question: are there any drugs that work for SARS-CoV or SARS-CoV-2 in animals?
Evidence: We show that a high (5106 pfu) and medium (5104 pfu) dose of SARS-CoV-2 induces consistent upper respiratory tract (URT) viral RNA shedding in both groups of six challenged animals, whilst a low dose (5102 pfu) resulted in only one of six displaying signs of URT viral RNA replication.  
Verdict: Neutral
Claim: all hand sanitizers works against covid-19 
Question: what hand sanitizers kill COVID-19?
Evidence: By extrapolating effectiveness of hand sanitizers on viruses of similar structure to SARS-CoV-2, this virus should be effectively inactivated with current hand hygiene products
Verdict: Supports
Claim: not all masks confer equal levels of protection
Question: what are the best masks for preventing infection by Covid-19?
Evidence: We found no direct high quality evidence on whether N95 respirators are better than surgical masks for HCWs protection from SARS-CoV-2.
Verdict: Neutral
Claim: Favipiravir, an antiviral drug used for influenza in Japan, is currently being studied in humans for treating COVID-19 in over 30 clinical trials (as of July 31, 2020). It is not known whether it is safe or helpful for this disease.
Question: Can favipiravir help treat COVID-19?
Evidence: In early research, the targeted antivirals remdesivir and favipiravir appear to benefit patients by decreasing viral replication; clinical trials suggest that remdesivir speeds recovery from COVID-19.
Verdict: Supports
Claim: Face masks could be giving people Covid-19 immunity
Question: Can face masks protect me from the coronavirus disease?
Evidence: Wearing medical masks or N95 masks (namely N95 respirators) can slow the virus spread and reduce the infection risk.
Verdict: Supports
Claim: VITAMIN D LEVELS increase COVID-19 MORTALITY RATES
Question: Does Vitamin D impact COVID-19 prevention and treatment?
Evidence: In Middle East, the recovery rate (r= 0.267) and mortality rate (r= -0.217) showed a medium correlation.
Verdict: Refutes
Claim: heart disease is the main cause of the death for COVID-19 patients
Question: how do people die from the coronavirus?
Evidence: Respiratory failure has been cited as the major cause of death
Verdict: Refutes
Claim: COVID-19 is shedding new light on how viruses can kick some patient's immune system into overdrive to deadly effect in what is known as a cytokine storm syndrome.
Question: will SARS-CoV2 infected people develop immunity?
Evidence: In this study, we collected blood from COVID-19 patients who have recently become virus-free and therefore were discharged, and analyzed their SARS-CoV-2-specific antibody and T cell responses. We observed SARS-CoV-2-specific humoral and cellular immunity in the patients. Both were detected in newly discharged patients, suggesting both participate in immune-mediated protection to viral infection.
Verdict: Neutral
Claim: While there is no evidence that infected animals can spread COVID-19 to humans, some pet owners might be concerned, understandably so, that their pet could become infected with COVID-19 and fall ill.
Question: Can animals spread COVID-19 to people?
Evidence: ferrets and cats are highly susceptible to SARS-CoV-2 as infected by virus inoculation and can transmit the virus directly or indirectly by droplets or airborne routes.
Verdict: Refutes
Claim: budesonide, commonly prescribed in the United States under the name Pulmicort, is a good treatment for COVID-19.
Question: Is dexamethasone effective for treating COVID-19?
Evidence: The recent Coronavirus [severe acute respiratory syndrome (SARS)-CoV-2]-associated multiorgan disease, called COVID-19, has high morbidity and mortality due to autoimmune destruction of the lungs stemming from the release of a storm of pro-inflammatory cytokines.
Verdict: Neutral
Claim: Experts anticipate some seasonal impact on the spread of the coronavirus, though the exact relationship is unclear.
Question: how does the coronavirus respond to changes in the weather
Evidence: These results provide evidence for the relationship between several weather variables and the spread of COVID-19. However, the (conservatively) estimated relationships are not strong enough to seasonally control the epidemic in most locations.
Verdict: Supports
Claim: The virus that causes COVID-19 appears to spread more efficiently than influenza but not as efficiently as measles, which is among the most contagious viruses known to affect people.
Question: has social distancing had an impact on slowing the spread of COVID-19?
Evidence: counties where the policies have been imposed have effectively increased social distancing and have seen slowing the spread of COVID-19.
Verdict: Neutral
Claim: certain marijuana strains could possibly prevent COVID-19 infection.
Question: Can smoking cannabis (weed) help in preventing COVID-19?
Evidence: Since many articles have reported the effect of smoking (tobacco and cannabis) and vaping in cerebrovascular and neurological systems, and considering that smokers are more prone to viral and bacterial infection compared to non-smokers, it is high time to explore the probable correlation of smoking in COVID-19 patients.
Verdict: Refutes
Claim: people can spread coronavirus even if they don't have symptoms (called asymptomatic) or before they have symptoms (called presymptomatic).
Question: Can face masks protect me from the coronavirus disease?
Evidence: Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets.
Verdict: Neutral
Claim: Some people with diabetes, a disease that affects the body's ability to produce or use the hormone insulin to reduce glucose (sugar) in the blood, may be concerned about being at higher risk of getting COVID-19. However, this is a misconception.
Question: what kinds of complications related to COVID-19 are associated with diabetes
Evidence: COVID-19 patients with diabetes were more likely to develop severe or critical disease conditions with more complications, and had higher incidence rates of antibiotic therapy, non-invasive and invasive mechanical ventilation, and death
Verdict: Neutral
Claim: ibuprofen may not be effective for COVID-19
Question: Are Tylenol, Advil and Motrin effective and safe to take for COVID-19 symptoms?
Evidence: There are currently no approved medications or vaccines which have been claimed to be effective in COVID-19 prevention or treatment.
Verdict: Supports
