Maputo — Nampula (Mozambique), 2 Jul (AIM) – About five per cent of the population of Nampula city in northern Mozambique have antibodies in their blood to the coronavirus that causes the Covid-19 respiratory disease.

This is one of the main results of an epidemiological survey in the city undertaken by the National Health Institute (INS).

The survey, held over ten days, was intended to reach a sample of some 8,000 residents of the city, but in fact it fell short – samples were only taken from 6,272 people. The survey used a blood test, which does not detect the coronavirus directly, but detects antibodies showing that the person in question has been in contact with the virus.

The survey found that the virus is present in all neighbourhoods of the city, but particularly in Natikiri and Namutequeliua, with a prevalence of 12 and 11 per cent respectively.

As for occupational groups, the survey found that five per cent of people working in commercial establishments (such as shops, bakeries and restaurants) had the anti-bodies in their blood, while the prevalence among policemen was six per cent, and among bus and minibus drivers only three per cent.

The group most exposed to the virus was market vendors – ten per cent of those surveyed had the anti-bodies in their blood. This is no surprise – the unhealthy conditions of the city’s teeming markets, particularly the huge wholesale market known as Waresta have been shown repeatedly on Mozambican television stations.

At Waresta, there was no attempt at social distancing, and thousands of people, many of them not wearing masks, were crammed into the narrow spaces between the vendors. Belatedly, Nampula Municipal Council has now closed down Waresta and two other markets for “re-organisation”.

The shut-down of the markets, supposed to be for just three days, has now lasted for a week. The municipal councillor in charge of managing markets, Osvaldo Momade, told reporters the Council is concerned to ensure that the markets are able to implement preventive measures against Covid-19.

There is no new date fixed for the re-opening of Waresta, much to the anger of vendors whose stalls have been demolished. While Waresta is being re-organised, the vendors have been moved to a temporary site in Natikiri neighbourhood, which is just as crowded and unhealthy as Waresta used to be.

Health Minister Armindo Tiago announced the preliminary results from the INS survey on Wednesday, at a meeting of the Nampula Operational Emergency Committee.
