Early mornings in Vietnam are a hive of activity in the local markets. People start setting up their stalls around 3am to get ready for the onslaught of people getting ready for their day.

Because things like refrigerators are still something of a luxury here, many people still shop every day. Even with refrigeration, a lot of people still prefer fresh fruit and vegetables every morning and many people shop 2 or 3 times a day.

The roads are busy every night with people transporting fresh produce from the countryside to the city. Some people (particularly from the West) worry because of the lack of refrigeration for meat and seafood especially.

Most of the seafood is sold alive. You go to the market, select your fish and the stallholder prepares it in front of you.

The meat is delivered every day and most stallholders only buy as much as they can sell in a day.

Me, I'm more concerned about the meat I buy from the supermarket. You don't know when it was slaughtered, how long it has been in storage or how many times it's been transported.

It's cut up and wrapped in plastic and how long before it's sold?

Give me the wet markets any day. Six years I've been living and shopping at the local markets here and never once have I been sick from eating the local produce.

I believe it's our obsession in the West with "germ free" that is making us sicker.

Did you know your body contains more bacteria and viruses than it does human cells? The question I have is, are we the host or are they? Without a good balance of good and bad bacteria, our immune system weakens and we are more susceptible to disease.

Is that what they're counting on with this lockdown?
