Two recent papers were published in JAMA on infants born to mothers who were infected with SARS-CoV-2. All of the available evidence suggested that the babies were not infected with the virus at the time of birth. Analysis of the babies' blood soon after birth showed that they all had high levels of IgG against SARS-CoV-2 and about half of them also had anti-SARS-CoV-2 IgM. Which of the following best explains this observation?

Group of answer choices:

A.The presence of anti-SARS-CoV-2 IgM and IgG antibodies in some of the babies indicates that their mothers were asymptomatic

B.The presence of anti-SARS-CoV-2 IgM in some of the babies indicates that viral antigens were transported into the blood of these babies

C.The lack of anti-SARS-CoV-2 IgM in some of the babies suggests that these individuals had an immunodeficiency syndrome

D.The presence of anti-SARS-CoV-2 IgG antibodies indicates that all of the babies must have been infected with the virus

E.The presence of anti-SARS-CoV-2 IgM antibodies in some of the babies indicates that these babies lacked helper T cells

Nonparametric: A small study is conducted to compare birth weight in babies born to mothers who do not smoke to those that smoke more than ½ pack/day. Is there a significant difference between birth weights due to maternal smoking status? Use the Mann-Whitney U test with a 5% level of significance. What is R1 (non-smokers)? Birth weights of infants in two groups of mothers. (Observed data) Nonsmokers Heavy Smokers (≥1/2 pack/day) 8.6 7.0 8.5 5.2 6.3 6.1 9.3 6.7 8.0...

Cotinine level(ng/ml) was measured in the meconium of newborns of mothers who were active, passive or nonsmokers. There were consecutive women arriving for delivery at one hospital. The alkaloid, cotinine is the main metabolite of nicotine. with a half-life of around 20 hours and detectable for several days after exposure, it is a biomarker for exposure to tobacco smoke. Cotinine level (ng/ml) Active Smokers (490, 418, 405, 328, 700, 292, 295, 272, 240, 232) Passive Smokers ( 254, 219,...

During a recent Ebola outbreak, researchers attempted extracting antibodies from people who had been infected but survived. They then injected other people with these antibodies to help them overcome the illness. Even more recently, an experimental vaccine against Ebola has been approved for emergency use in the Democratic Republic of the Congo. Ebola is a virus that infects macrophages and dendritic cells. In doing so, it causes dysregulation in several ways. For example, 1) it prevents infected cells from secreting...

In randomized, double-blind clinical trials of a new vaccine, infants were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose,114 of 726 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 71 of 607 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a...
