Are we getting enough out of Health related IEC/BCC?

Today, I happened to witness an IEC/BCC programme conducted on the premises of a busy Government hospital. The programme included short speeches, songs and skits being performed by a troop who appeared very experienced and confident in what they were doing.
I just looked around to see the people who were supposed to take the messages home. I saw about half a dozen people sitting on the nearby verandah, apparently listening and watching the show. Apart from this small group there were hardly any listeners even though there was a good crowd. There were people waiting in the OP queue eagerly awaiting their turn or straining their ears so as not to miss hearing their token number in the noisy atmosphere.
There were people moving about to find the correct service station such as OP ticket counter, pharmacy, lab, nursing station etc. Others were accompanying the sick and busy looking after them. The show was progressing amidst this crowd of crying children, worried faces and anxious bystanders.
Since I had some spare time before office hours, I decided to be part of this indifferent audience.
To be frank, I expected some encouragement from  the mode of presentation and the topic. But  it felt odd to listen to prevention of monsoon diseases on a hot humid morning and when the monsoons are expected only after 2 months. I just realized the reason behind the pessimistic view of one of my teachers towards the outcome of IEC/BCC when used beyond a certain extent. I wondered as to why monsoon preparedness is being projected so early at the start of summer.
There may be only 1 or 2 teams capable of and entrusted with such programmes who have to cover the entire state before June. The Government funds of the current financial year may have been left unutilized till now.
The programme repeatedly stressed on vector-borne diseases, diarrhea, leptospirosis, hepatitis and other diseases common during monsoon. What was lacking was the stress on the fact that many of these diseases are common during the hot & humid summer also. There are habits that should be followed irrespective of the season such as hand washing, drinking boiled & cooled water, food hygiene, personal hygiene and good sanitary practices. In addition there are precautions to be followed in summer such as adequate hydration & avoiding excessive sunlight.
Healthy habits are difficult to cultivate and people tend to be having a short memory in these aspects. What is required is appropriate communication of relevant information at an appropriate time in a receptive atmosphere.
