The coronavirus has most of us worried for the future and for our friends and family's health.

But while some are trying to protect their family from the virus, others are trying to make a profit off people's fears.

Here at Mashable Southeast Asia, we've been keeping a tally of cases where jerks have been doing so. Here are 5 cases of people selling face masks for much higher prices than they have any right to be.

This dude from Jurong West, Singapore.

Alexie Tan made a Facebook post on January 8 after witnessing a man's pop-up store using the back of his car at Jurong West, Singapore.

"This kind of people who hoard mask is already bad enough and still sell at SG$1 (US$0.72) per piecce, SG$40/box (US$28.81) illegally," Tan wrote in the Facebook post. "Please reflect on yourself. Don't 趁火打劫 (which roughly translates to the Chinese idiom 'loot a burning house')."

House of Seafood, Singapore.

Already infamous for introducing a live crab claw machine in their restaurant, House of Seafood is back again with another controversy.

On February 9, the restaurant shared a post encouraging customers to visit the restaurant for a "special" offer of a box of surgical masks for SG$21.40 (US$15.41).

After receiving backlash, the restaurant deleted the post and has since made an update offering free masks to all customers.

Qoo10 sellers and Carousell, online.

Several online sellers on e-commerce platforms such as Qoo10 and Carousell have listings for face masks at prices that are way too much.

Several sellers on Carousell have been reported for re-selling disposable face masks at much higher prices than they were bought for.

Mothership.Sg reported that one of these sellers even listed a box of 20 N95 face masks for more than 5 times its original price at a whopping SG$288 (US$207.45).

Qoo10 was a bigger concern for authorities, however. It had a listing advertising "anti-coronavirus," "anti-pneumonia," and "anti-haze" face masks. Here's the kicker: 30 masks were being sold for SG$10,000 (US$7203). The listing has since been taken down.

A shop at Nee Soon East, Singapore.

Singaporean politician Louis Ng Kok Kwang also posted on Facebook on January 8 after confronting staff at a Nee Soon East shop for selling a box of 20 N95 masks for SG$138 (US$99.40). The shop was also selling each mask for SG$6.90 (US$4.97).

"Anyone can sell masks but no one should be profiteering. Retailers profiteering from the situation will be taken to task. MTI has been alerted and they will investigate," Ng wrote in his post.

"This is a time when we all need to come together and help each other rather than try to take advantage of the situation and profit from it. Let’s stay calm, stay united and together we will beat this virus."

Bonus round: These online sellers are selling Maggi for at least 4 times their cost.

On February 7, Singapore moved its Disease Outbreak Response System Condition (DORSCON) level to orange. Cue the outbreak of panic among Singaporeans leading to multiple social media posts about long lines in grocery stores and items flying off market shelves.

It's at the point where because of the empty shelves, people are reselling food on e-commerce sites.

Facebook group SG Kay Poh found several sellers on Carousell also reselling instant noodles. Which normally, wouldn't be an issue.

That is, if they were being resold for insane prices.

Although people are arguing the legitimacy of these posts, the fact that it's something that could happen is enough to give me a headache.

But there is a positive side to what's going on right now.

A 4-year-old girl was the first to recover from the coronavirus in Malaysia. More recovery cases have followed.

Thankfully, there are still good samaritans out there helping their fellow Singaporeans. Take this "Resident" who left a bottle of hand sanitizer and face masks for free in their apartment complex for example.

Let's hope more people follow those positive actions and start helping each other instead.
