The total number of COVID-19 deaths thus far exceeds the number of abortions over two days worldwide

The number of abortions occurring worldwide over two days is roughly 400,000, based on annual estimates from between 2015 and 2019 from a study published in July 2020 in the journal The Lancet Global Health. Although the global number of abortions carried out over two days did exceed the total number of COVID-19 deaths reported in March 2020, when this claim surfaced, the number of deaths from COVID-19 has been growing steadily over time. In fact, the global number of COVID-19 deaths approached and crossed the 400,000 mark in June 2020. Therefore, this comparison is no longer accurate.

COVID-19 has caused many deaths due to high virus transmission, despite its relatively small infection fatality ratio

The infection fatality ratio (IFR) is the proportion of deaths among all infections, both confirmed and undetected cases. While the IFR for COVID-19 is relatively low for most people except for the elderly, it is only one factor to consider when assessing the public health threat posed by a disease. Despite its relatively low IFR, COVID-19 has caused a large number of deaths due to its high transmission. In less than a year, more than 200,000 deaths have occurred in the U.S. and at least 1 million deaths have occurred worldwide as a result of COVID-19.

Using face masks does not increase the risk of skin or oral infections

Face masks are effective at reducing the spread of the virus that causes COVID-19 by limiting the transmission of respiratory droplets. Scientific evidence does not support the claim that wearing face masks increases the risk of oral and skin infections or bacterial overgrowth. In some cases, prolonged wearing of face masks might cause skin irritation, but this can be prevented by selecting comfortable masks and following proper hygiene guidelines.

COVID-19 vaccines do not modify the human genome and do not involve hydrogels; hydrogels are not internet-connecting devices

No evidence suggests that COVID-19 vaccines will use hydrogels, which are polymers that swell without dissolving when in contact with water. Hydrogels are not a recent discovery; they have been publicly known and extensively used in biomedical research for decades. Hydrogels do not connect to the internet. Finally, mRNA-based vaccines for COVID-19 cannot alter the human genome, which is made of DNA.

Telegraph article describing the hypothesis that face masks can variolate a population receives mixed reviews on its scientific accuracy

“The Telegraph headline is obviously misleading but the subheading is accurate. Masks don’t give immunity; rather, the argument is that infections are milder or asymptomatic and allow immunity without severe disease. The article is essentially true to the NEJM commentary, however a reader could become confused and think that the article suggests masks give you COVID-19 immunity.”

The genetic features of the virus causing COVID-19 are compatible with natural evolution, and therefore, don’t prove that the virus was constructed

Although the exact origin of the SARS-CoV-2 virus remains unknown, previous claims that the virus contained artificial elements or that it had been patented were debunked. The virus most likely originated in nature, probably in bats, according to the genetic similarity between SARS-CoV-2 and other animal coronaviruses. Dr. Yan claims to prove that the SARS-COV-2 virus originated in a lab, but a careful analysis of her pre-print actually shows this claim is unsubstantiated.

Tuberculosis, the flu, and COVID-19 differ in disease prevalence and burden, requiring different public health responses

COVID-19, tuberculosis (TB), and the flu are all respiratory illnesses that spread through the air, hence protective measures recommended for these diseases are similar. However, the three diseases differ in disease prevalence and burden, leading public health officials to devise recommendations specific to each disease. Unlike TB and the flu, there are no effective treatments or vaccines for COVID-19. The number of TB cases in the U.S. is extremely low, and the flu has a lower mortality rate than COVID-19. These factors taken together explain why public health measures for controlling COVID-19 spread are needed in the community, but not implemented in the case of TB and the seasonal flu.

No vaccine contains strains of both the flu and the virus that causes COVID-19; COVID-19 is not the flu

COVID-19 and the flu are both viral respiratory illnesses, however they are caused by very different viruses that belong to two distinct and separate families of viruses. SARS-CoV-2, the virus responsible for COVID-19 is not a strain of flu. Although flu shots are now being distributed in preparation for the upcoming 2020-2021 flu season, the vaccines are not mixed with a COVID-19 vaccine. No vaccine is available against COVID-19 as of September 2020.

The number of COVID-19 cases reported is based on a highly specific diagnostic test for COVID-19; no confusion with flu or common cold is possible

Determining the spread of COVID-19 relies mainly on the detection of confirmed cases. Cases are confirmed using PCR tests which specifically detect the presence of genetic material from SARS-CoV-2, the virus responsible for COVID-19, and which do not detect viruses that cause the flu and the common cold. Therefore, even though the flu and the common cold can produce symptoms similar to a mild case of COVID-19, cases of the flu and the common cold would not be included in the reported numbers of confirmed COVID-19 cases.

Cloth masks are effective at reducing virus transmission because it spreads in respiratory droplets, which are larger than smoke particles and the pores in fabric

When considering effective mechanisms for reducing virus transmission, it is the size of respiratory droplets—rather than the size of the virus itself—that needs to be considered. While viruses are smaller than smoke particles or the pores in the fabric of a cloth mask, viruses cannot travel in the air on their own and must be carried by respiratory droplets, which are much larger than smoke particles or pores in fabric. Therefore, cloth masks are effective at reducing virus transmission as they block respiratory droplets, but ineffective at reducing smoke particle transmission.
