Since the first confirmed case in Singapore, certain individuals have been spreading fake news about the virus on internet forums and chat groups. These claims have been debunked by government authorities. This entry highlights the common scientific speculations about the virus and the confirmed facts debunking the major fake news cases.

Common speculations

Fresh information about the virus continue to surface as scientists and virologists worldwide conduct independent research. As this is a rapidly developing situation, these findings have yet to be confirmed by a global health authority. The following are the common speculations that have come to light.

Bats were the host animals for the SARS coronavirus in 2003. Photo from Business Insider Singapore.

Bats could be the original host animal

So far, researchers have found out that the genetic make-up of the nCov-2019 is 96% identical to coronavirus found in fruit bats.[1] It is unlikely that snakes are the main source of the zoonotic transmission. However, there is no confirmation on what animal infected patient zero. Bats could have passed the virus onto another species sold at Huanan Seafood Wholesale Market.[2][3]

Virus could have originated outside of Huanan Seafood Wholesale Market

Studies have shown that 2019-nCov may have been passed from animal to human before entering the Huanan Seafood Wholesale Market.[4][5] The lack of proper hygiene practices at the market and close human proximity may have only exacerbated the virus transmission.[6][7]

Virus could be deadlier than SARS

The speculation that 2019-nCOv is deadlier than SARS is inconclusive. It is based on an initial study conducted by a group of Hong Kong scientists. They posit that the fatality rate of infected individuals stands at 14% (4 out of 29 severely-ill patients). However, there is not enough information for a clear estimate as the outbreak is still growing and being investigated.[8]

Virus could be more contagious than SARS

The speculation that 2019-nCOv is more contagious than SARS is inconclusive. Chinese officials claimed that the 2019-nCov could be asymptomatic, unlike the SARS virus. This means that infected individuals could still be infectious despite not showing any symptoms.[9][10]

Clarification of fake news in Singapore

The facts in this section have been cross-checked with official statements from the relevant authorities. These include the Ministry of Health (MOH) and other local government bodies.

Fact: No deaths in January 2020

False Claims Status Fact Fact-Checking Authorities Refs.
“First death” in Singapore Debunked There were no deaths caused by the 2019-nCov virus in January 2020. Factually [11][12]
"Death" from visiting a shopping mall in Singapore Debunked Ministry of Health (MOH) [13]
Factually [14]

The following table documents the weekly and monthly tally of confirmed infected individuals in Singapore for January 2020. The first suspected case was reported on 4 January 2020 (Week 1).

January 2020 Confirmed Cases Deaths Refs.
Week 1 - - -
Week 2 - - -
Week 3 - - -
Week 4 4 - [15][16][17]
Week 5 6 - [18][19][20]
Total 10 0 -

As of 30 January 2020, all 10 individuals are from Wuhan with no Singaporeans infected.[21] For a more detailed timeline of how the virus came to Singapore, refer to this entry.

Fact: Public hospitals are safe to visit

On 24 January 2020, the Ministry of Health (MOH) debunked the assumption that certain public hospitals were unsafe because of the virus.

False Claim Status Facts Fact-checking Authorities Refs.
Avoid visiting certain public hospitals as suspected and confirmed cases have been quarantined at said locations. Debunked All public hospitals in Singapore follow established safety protocols to isolate suspected and confirmed cases. Factually [22][23]
Infected individuals are kept in negative pressure (NEP) isolation rooms. Contaminated air goes through filters and is UV-treated before being released. Ministry of Health (MOH) [24]
All 9 public hospitals in Singapore have these negative pressure (NEP) isolation rooms. [25]

Fact: Virus transmitted through cough & sneeze droplets

False Claim Status Facts Fact-checking Authority Refs.
Keep throat "constantly moist" to prevent infection Debunked A moist throat does not deter infection. Ministry of Health (MOH) [26][27]
An individual is infected when contact is made with cough and sneeze droplets carrying the virus.

According to the Ministry of Health (MOH), there is no known vaccine for the Wuhan virus (2019-nCov) as of January 2020. Therefore, all information regarding home remedies and self-medication (such as the above) are presumed to be false until confirmed by a legitimate health authority.

Fact: Restricted entry for Chinese travellers

On 25 January 2020, the Immigration and Checkpoints Authority (ICA) debunked rumours that Wuhan travellers were denied entry into Singapore. This was three days before Singapore officially declared a limited travel ban on travellers from Hubei province, China. The limited travel ban was an official response to the increasing number of infected individuals from Wuhan in Singapore.

False Claim Status Facts Fact-checking Authorities Refs.
100 arriving travellers from Wuhan were "denied" entry

(25 January 2020)

Debunked Singapore did not turn away visitors from Wuhan before 28 January 2020. Immigration and Checkpoints Authority (ICA) [28]
Factually [29]
Only on 28 January 2020 was there a restriction on travellers from Hubei. Ministry of National Development, Wuhan Virus Task Force [30]
