Letters home: how Singapore's migrant dormitories became the outbreak

By the first week of May 2020, foreign workers living in purpose-built dormitories — predominantly labourers from India, Bangladesh and China — accounted for the overwhelming majority of Singapore’s confirmed coronavirus cases. The daily figures separated the two populations, and once they did, the disparity was the story.

Two counts, one country

The Ministry of Health’s daily releases reported cases in two groups: those in the general community and those among dormitory residents. That separation was a reporting decision rather than a medical one, and it made something visible that a single total would have hidden.

The community figure stayed low through April. The dormitory figure did not. For weeks the daily total was dominated by one population living in one kind of accommodation, and the ratio between the two counts became the most-quoted number of the period.

What a dormitory is

Purpose-built dormitories house workers in the construction, marine and process sectors. Rooms are shared, typically by ten to twenty men, with communal kitchens, washing facilities and recreation areas. The largest sites hold several thousand residents.

The arrangement predates the outbreak by decades and is regulated: dormitory operators are licensed, and standards for space per resident, sanitation and amenities are set in law. What the outbreak established is that those standards were written for ordinary conditions, and that a respiratory virus in shared accommodation behaves differently from one in single-household housing.

What was done

Affected dormitories were gazetted as isolation areas, with residents confined to them. Workers in essential sectors were moved to alternative housing — vacant HDB blocks, floating accommodation, military camps and exhibition halls converted for the purpose — to reduce density. Medical posts were set up on site, and testing was extended across the dormitory population rather than to symptomatic cases alone.

Movement restrictions for the general population, in force from early April, applied to dormitory residents as well, with the additional effect that confinement was to a shared room rather than a home.

The questions it produced

The dormitory outbreak became a recurring subject in Parliament, and the questions fell into three groups.

On foreseeability. Whether the density of dormitory accommodation had been identified as a risk before the outbreak, and whether any assessment of it existed.

On the response. How quickly dormitories were gazetted after the first cases, what medical provision was made on site, and how workers unable to work were paid.

On the standards. Whether the licensing requirements for space, sanitation and occupancy would be revised, and on what timetable.

Ministers answered across several sittings, and the substantive commitments made concerned future dormitory standards — lower occupancy, more space per resident, better separation of facilities — rather than the handling of the outbreak itself.

What the workers were dealing with

The men in the dormitories were confined, in many cases unable to work, and separated from families they support financially and had not seen for long periods. Communication home was by phone, and news of the outbreak reached those families as international coverage before it reached them as reassurance from the men themselves.

Several accounts published at the time described the same specific anxieties: whether wages would continue, whether the confinement would be extended, and what families at home were being told. The combination — unable to work, unable to leave, unable to reassure anyone — is what distinguished this confinement from the one the rest of the country experienced.

Remittances are the reason most of these men are in Singapore. A stoppage that lasts weeks is not an inconvenience; it is the household income of a family in another country.

Why the separation in the figures mattered

Reporting the two counts separately was defended on the grounds that the epidemiological situations were genuinely different, and that a combined figure would have misrepresented the risk to the general community.

The criticism was that the separation also made it easy to read the national position as better than it was, and that a population inside the country’s borders, working in its economy, was being counted as a category rather than as part of the total.

Both readings are available from the same releases. What is not in dispute is that without the separation, the scale of the dormitory outbreak would have taken considerably longer to become publicly obvious — which is an argument for the separation rather than against it.

What changed afterwards

The commitments made during the period concerned new standards for dormitory accommodation: reduced occupancy per room, increased living space per resident, and improved sanitation and separation. New builds were to meet the revised standards, with existing dormitories brought up over a longer timetable.

Whether the revisions went far enough was argued at the time and has been argued since. The substantive point established by 2020 is narrower and harder to dispute: accommodation standards written for ordinary conditions determined how a large population fared in conditions that were not ordinary, and that link had not been examined before it was tested.

Why the density was not incidental

The reason dormitory accommodation behaved differently is arithmetical rather than mysterious.

A household of four sharing a flat produces a small number of contacts. A room of sixteen sharing communal kitchens, washing facilities and corridors with several hundred others produces a very large number, and produces them continuously rather than in episodes. Isolating a case inside such a building is close to impossible without moving people out of it, which is why relocation rather than confinement became the operative response.

Nothing about that was unknowable in advance. What had not happened was the step of asking what the standards would mean during a respiratory outbreak — and standards that are adequate in ordinary conditions are not self-evidently adequate in others.

The pay question

The question that recurred most in parliamentary exchanges was the simplest: who pays a worker who cannot work because the building he lives in has been gazetted.

Employers remained responsible for salaries during the period, and support was extended to firms to make that sustainable. For workers on basic pay plus overtime, however, the arithmetic is not the basic rate alone — overtime is a substantial part of what is actually earned and sent home, and it stops when work stops.

That gap between “wages continued” and “income continued” is the difference between the formal answer and the household consequence, and it accounts for much of the anxiety reported at the time.

What the period established about the counting

One lasting effect of the two-column reporting is methodological rather than political.

Once a population is counted separately, every subsequent statement about the national position has to specify which figure it refers to. Comparisons with other countries, assessments of the restrictions, and judgements about when to reopen all became questions of which denominator was in use.

That is a real cost of the separation, and it is the strongest argument for the criticism made at the time: a category that exists in the data starts to exist in the reasoning, and a population inside the country’s borders ends up discussed as a variable rather than as part of the total.

The part that was not new

Dormitory accommodation, its standards and its density were not discovered in 2020. They had been raised before — by non-governmental organisations working with migrant workers, in occasional press coverage, and in Parliament — generally in the context of individual welfare cases rather than systemic risk.

What changed was not the information but its consequence. Conditions that had been treated as a welfare question became an epidemiological one, at which point the same facts produced a national emergency rather than a recurring complaint.

That is worth stating plainly because it bears on the foreseeability question raised in the House. The standards were known, the density was known, and the population was known. What had not been done was to put those three facts together and ask what they would mean under a respiratory outbreak — which is a different failure from not having the information, and a more correctable one.

Why the phrase stuck

The image that carried the period was not a statistic. It was correspondence: men writing home to families who were reading about Singapore’s outbreak in international coverage and had no way to check whether the person they were reading about was theirs.

That framing did something the case numbers could not. A dormitory count is a category; a letter is a household. The second is what made the first legible to people who had never been inside such a building and had no reason to think about how it was arranged.

It also set the terms of the argument that followed. Once the population had been described as families rather than as a statistical group, the question of whether they belonged in the national total answered itself for most people who considered it.

Where to check this

Daily case figures, split between community and dormitory-resident cases, were published by the Ministry of Health throughout the period. The gazetting of dormitories as isolation areas, the relocation of essential-sector workers and the medical provision made on site were announced by the Ministry of Manpower. Parliamentary questions and ministerial replies on dormitory standards, occupancy and worker pay are in Hansard, the official verbatim record of proceedings published by the Parliament of Singapore. Licensing requirements for purpose-built dormitories are in the Foreign Employee Dormitories Act.
