GIS mapping for Covid-19 control

The GMOA has quite rightly given an ultimatum to the Ministry of Health that it will withdraw from the Technical Committee for Covid-19 control, if Geographical Information System (GIS) maps of Covid-19 patient-locations will not be made available. Being an organization, which has many knowledgeable specialists in the area of epidemiology, I believe they have understood the valuable inputs such maps can give to the control teams to prevent escalation of this epidemic. The maps are also valuable tools to inform the general public of the locations of the patients so that they can avoid such areas. I think the Presidential Task Force also should be shown these maps if they have not done it yet.
Twenty years ago, realizing the value of GIS maps, I used them for dengue control in Colombo and it provided great information to plan and implement control measures. We could see clusters of patients and the gradual movement of the cluster into newer areas with time. My maps were used at least at Peradeniya University to train Medical Officers in Health mapping. There are some experts in GIS mapping in the Ministry of Health now, and they could be used to map the patient locations and also put in other information. The Public Health Department of CMC gave GPS training to Public Health Inspectors those days to send in the information from the location to the GIS centre at the Town Hall, where all the information was collated. We then prepared the maps and sent them out to the MOHs and also discussed the situation at meetings. I hope they have continued that work and if so, they also should put out maps of present patient locations, so that the people in Colombo will also know which areas in the city they should avoid. Colombo city will possibly be the next centre of transmission Covid-19 in the country.
Technology should be used in disease prevention as much as possible, but unfortunately the analyzed information is hardly available to the people who make decisions and those in the field. This attitude has been in the health sector for decades. I hope that the authorities will seriously take note of this, as this is public information that can be used for the greater good of our people, and not to be put away in storage as someone’s private property.

Haphazard demolition in Nugegoda and deathtraps

The proposed expansion of the Kelani Valley railway line has prompted the squatters to demolish the buildings and the above photograph depicts the ad-hoc manner in which a building in the heart of Nugegoda town (No 39 Poorwarama Road) has been haphazardly demolished posing a risk to the general public. Residents say that the live electric wire has not been disconnected and the half-demolished structure is on the verge of collapse, causing inevitable fatal damages.

Aviation and doctors on Strike

On July 19, 1989, United Airlines Flight 232 departed Denver, Colorado for Chicago, Illinois. The forecast weather was fine. Unfortunately, engine no. 2 – the middle engine in the tail of the three-engined McDonnell Douglas DC 10 – suffered an explosive failure of the fan disk, resulting in all three hydraulic system lines to the aircraft’s control surfaces being severed. This rendered the DC-10 uncontrollable except by the highly unorthodox use of differential thrust on the remaining two serviceable engines mounted on the wings.
Consequently, the aircraft was forced to divert to Sioux City, Iowa to attempt an emergency crash landing. But the crew lost control at the last moment and the airplane crashed. Out of a total of 296 passengers and crew, 185 survived.
The National Transportation Safety Board (NTSB) declared after an investigation that besides the skill of the operating crew, one significant factor in the survival rate was that hospitals in proximity to the airport were experiencing a change of shifts and therefore able to co-opt the outgoing and incoming shift workers to take over the additional workload of attending to crash victims.
One wonders what would have happened if an overflying aircraft diverted to MRIA-Mattala, BIA-Colombo, Colombo International Airport Ratmalana (CIAR) or Palaly Airport, KKS during the doctors’ strike in the 24 hours starting March 12, 2025? Would the authorities have been able to cope? International airlines (over a hundred a day) are paying in dollars to overfly and file Sri Lankan airports as en route alternates (diversion airports).
Doctors in hospitals in the vicinity of the above-named international airports cannot be allowed to go on strike, and their services deemed essential. Even scheduled flights to those airports could be involved in an accident, with injured passengers at risk of not receiving prompt medical attention.
The civil aviation regulator in this country seems to be sitting fat, dumb, and happy, as we say in aviation.

HW Cave saw Nanu Oya – Nuwara rail track as “exquisite”

Plans to resurrect the Nanu Oya – Nuwara Eliya rail track are welcome. The magnificent views from the train have been described by H W Cave in his book The Ceylon Government Railway (1910):
‘The pass by which Nuwara Eliya is reached is one of the most exquisite things in Ceylon. In traversing its length, the line makes a further ascent of one thousand feet in six miles. The curves and windings necessary to accomplish this are the most intricate on the whole railway and frequently have a radius of only eighty feet. On the right side of the deep mountain gorge we ascend amongst the tea bushes of the Edinburgh estate, and at length emerge upon a road, which the line shares with the cart traffic for about a mile. In the depths of the defile flows the Nanuoya river, foaming amongst huge boulders of rock that have descended from the sides of the mountains, and bordered by tree ferns, innumerable and brilliant trees of the primeval forest which clothe the face of the heights. In this land of no seasons their stages of growth are denoted by the varying tints of scarlet, gold, crimson, sallow green, and most strikingly of all, a rich claret colour, the chief glory of the Keena tree’.
However, as in colonial times, the railway should be available for both tourists and locals so that splendid vista can be enjoyed by all.
