WEEKLY CALENDAR (2008, 2009, 2010, 2011 all in one page with laminating)

Use this calendar to help you determine if you should give a particular service to a child you are seeing. For example, it can help you calculate how old a child is or how many weeks have passed since the child received a DPT vaccination in order to decide what vaccinations you should give the child today.

The application of weekly calendar is done in stages:

  1. Spread the weekly calendaron your table.
  1. Ask mother, when her baby was born (or find the birth date in the child’s LISIO).

The mother says, e.g.,“My baby was born on March 18, 2008.”

  1. Look at the calendar: March 18, 2008 (when the baby was born) is in what week?

March 18, 2008 is 12th week.

  1. What is today’s date?

For example: Today’s date is May 5, 2008.

  1. What week is today in?

Look at the calendar. May 5, 2008 is in the 18th week.

  1. Therefore, the age of the baby now is:

18th – 12th = 6th weeks old

To assess immunizations:

For OPV (polio) and DPT (or DPT-HepB) vaccination, the child must be at least 6 weeks old, and at least 4 weeks must have passed since the previous dose of the same vaccine. For measles vaccination, the child must be at least 9 months (40 weeks) old.

  1. Ask the mother what vaccinations her baby has already receivedand when (confirmed by the LISIO if possible)

For example, a mother saysBCG and OPV on March 23, 2008.

  1. Look at the calendar: March 23, 2008 is in what week?

March 23, 2008 is in the12th week.

  1. What to give today (May 5, 2008)?

DPT-HepB1, OPV1

  1. How long until the next vaccination?

4 weeks, i.e. 18th + 4 = 22ndweek

  1. When is exactly after 4 weeks time?

22ndweek is June 2, 2008. So, you will ask mother to bring her baby for the next vaccination (DPT-HepB2, OPV2)on June 2, 2008.

NB: all antigens are given to the child according to age in weeks, except measles in months(9 months = 40 weeks)

Spread the calendar out on your table and try to calculate the following examples:

Find out when the baby was born / Look at the calendar to find the week the baby was born / What is today’s date? / What week is today in? / So the age of the baby now is: / Find out the vaccinations already received / Look at the calendar to find in what week the last vaccinations were given / Decide what to give today / How long until the next vaccination? / When is exactly after 4 weeks time?
April 28, 2008 / 17th week / May 5, 2008 / 18th week / 18th – 17th = 1st week / None / None / BCG & OPV0 / 5 weeks i.e. 18th + 5 = 23rd week / June 9, 2008
November 20, 2008 / 47th week / December 8, 2008 / 49th week / 49th – 47th = 2nd week / BCG & OPV0 / November 20, 2008 / None / 2 weeks i.e. 49th + 2 = 51st week / December 18, 2008
November 1, 2008 / 44th week / December 8, 2008 / 49th week / 49th – 44th = 5 week / BCG / November 20, 2008 / None / 1 week i.e. 49th + 1 = 50th week / December 11, 2008
To assess vitamin A and de-worming:
  1. Look at the calendar onvitamin A for children 1 – 4 years old. It will show the vitamin A distribution weeks twice a year; e.g., February (6th,7th,8th,9th week of 2009) and August (32nd, 33rd, 34th, 35thweek of 2009).
  1. De-worming. This depends on how high the worm prevalence of children 1 – 4 years or primary school children.

2.1.Where the prevalence of worms (by stool examination) is > 50%,Albendazole should be given twice a year to all children in the area, followedby vitamin A. Then, we assess the prevalence after Albendazole mass treatment.If, for example,a prevalence of 27% falls into the category of point 2.2 (below), and so on.

2.2.Where the prevalence of worms is 20 – 50%, Albendazole is given once a year (either February or August) to all children.

2.3.Where the prevalence is < 20%, Albendazole is given only to individual children who have worms.

To assess a child 18 months old who has come to the clinic for vaccination, vitamin A and de-wormingtreatment:

1.Vaccination.

  • Ask the mother when her child was born
  • She says (for example) January 4, 2008.
  • Look at the calendar: 1st week of 2008.
  • Whenwas her child immunized and for what?
  • December 29, 2007: BCG, DPT-HepB1, OPV1, measles
  • Look at the calendar: December 29, 2008 is 52nd week.
  • What is today’s date?: August 2, 2009
  • Look at the calendar: August 2, 2009 is 31st week of 2009.
  • So 31 weeks ago the child received the BCG, DPT-HepB1, OPV1, and measles.
  • Then today, you should give DPT-HepB2, OPV2.
  • How long until the next vaccination?
  • 4 weeks, i.e. 31st + 4 = 35th week
  • 35th week means August 30, 2009 for DPT-HepB3, OPV3.

2.Vitamin A and De-worming.

The answer is similar to the above, “to assessvitamin A and de-worming.”
