Delayed monsoon has altered disease pattern in region,say doctors

Though the rain gods finally seem to be smiling over the region,doctors say the disease pattern linked with the onset and withdrawal of monsoons is already altered this season.

Though the rain gods finally seem to be smiling over the region,doctors say the disease pattern linked with the onset and withdrawal of monsoons is already altered this season.

Cholera cases have shown a late rise,delayed by over a month,while malaria is likely to continue for a bit longer this time,say experts.

“There are certain infectious seasonal diseases that are strongly liked to the weather. For example,cholera and diarrhoea cases are usually reported before and during the monsoon and subside as the rains progress. Malaria normally raises its ugly head thereafter and before the onset of winters while dengue cases start coming up after the monsoon season ends,” explains a doctor.

This year,however,the trend seems contrary to the regular pattern. As the Health department here has witnessed,the cases of cholera which are usually reported in May,saw a surge in the end of June and July. The numbers are still piling up in the city as the first case of cholera was confirmed this month.

Even as Chandigarh observed July as the anti-malaria month,officials say the late onset on monsoon would extend the season for malaria and the cases would rise further.

“Delayed monsoon would mean that cases of malaria are likely to be more in August than last year,” said an official.

Malaria cases recorded by the Health department till now are around 40 per cent less than the previous years and the numbers are soon going to catch up with the continuing spells of rain in the coming month as predicted by the Met department.
