You will be shown a claim about public health, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT". If the abstract does not provide enough information to arrive at a verdict, write "NEI" (for "not enough information").
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract. If the verdict was "NEI", then return an empty array.

For instance, if the model were given the claim "wearing masks can prevent the spread of COVID", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that mass mask-wearing reduces the transmission rate for COVID-19."]
}

Claim: Can people who are asymptomatic spread coronavirus? The answer is NO

Abstract:
INTRODUCTION: A new coronavirus, called Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-CoV-2), has emerged from China in late 2019 and has now caused a worldwide pandemic.
The impact of COVID-19 has not been described so far in a military setting.
We therefore report a case series of infected patients in a recruit school in Switzerland and the herein associated challenges.
METHODS: Retrospective review of COVID-19 cases among Swiss Armed Forces recruits in the early weeks of SARS-CoV-2 pandemic in the canton of Ticino, the southernmost canton of Switzerland.
Positive cases were defined with two positive PCR testing for SARS-CoV-2 from nasopharyngeal swabs.
Serological testing was performed with a commercially available kit according to manufacturers' instructions.
RESULTS: The first case was likely contaminated while skiing during weekend permission.
He became symptomatic 4 days later, tested positive for SARS-CoV-2 and was put into isolation.
He showed complete symptom resolution after 48 hours.
Quarantine was ordered for all recruits with close contact in the past 2 days, a total of 55 persons out of 140 in the company.
Seven out of nine recruits in one particular quarantine room became mildly symptomatic.
SARS-CoV-2 PCR was positive in one of them.
Seven days after initial diagnosis, the index patient and the other one from the quarantine retested positive for SARS-CoV-2, although they had been completely asymptomatic for over 96 hours.
Serological testing revealed positive for both patients.
All others showed negative IgM and IgG. CONCLUSIONS: Young healthy recruits often showed a mild course of COVID-19 with rapid symptom decline but were persistent SARS-CoV-2 carriers.
This illustrates how asymptomatic patients may be responsible for covert viral transmission.
An early and prolonged establishment of isolation and quarantine for patients and close contacts is essential to slow down the spread of SARS-CoV-2, especially in the confined space of a military environment.
