Yes.
In business buildings that have central air-conditioner, a single infected person can transmit the virus to everyone in the building via the air-ducts.

In most part of their high temperatures are different from that in Hong Kong and most of the households do not have air conditioners. However, 釜山 and a few other location are really hard to stand.
The main point is whether they have a lot of air-conditioners. If there are no air-conditioners, then hot weather can help us a lot to combat the virus.
Money and tradition are also the factors.
Some of my relatives are living in Minnesota which is the coldest State in USA. They do not have air-conditioners at home, but their restaurants have air conditioners.
Actually, most very cold places have a very high summer (but the very hot summer days is few), so they did not have air-conditioners. However, as the economic development and global warming, the business buildings in these places begin to install air-conditioners.
Anyway, their hot days will not begin in late May or early June so they have more time. In some places, they just don't have air-conditioners at all, then they have the whole summer to help. In Hong Kong, some people will turn on the air-conditioners within the next few days.
