CDC Monthly Bulletin for Year 2016

Year 2016-December

The influenza positivity rate in December is lower compared to previous month. Influenza A was the most predominant subtype detected, followed by influenza B. 17 out of 67 samples from children less than 5 years of age were tested positive with respiratory syncytial virus (RSV).
From January to December 2016, 12 SARI samples were isolated with Burkholderia pseudomallei. Drug sensitivity was high with Ceftazidime (100%), Imepenem (100%) and Amoxicillin+Clavulaic (92%).


Year 2016-November

The influenza positivity rate in November is lower compared to previous month, but higher compared to the same period last year. Influenza A was the most predominant subtype detected, followed by influenza B. 29 out of 126 samples from children less than 5 years of age were tested positive with respiratory syncytial virus (RSV). From September to November 2016, 11 SARI samples were isolated with Pseudomonas aeruginosa. Drug sensitivity was high with Gentamicin, Ceftazidime, and Cirprofloxacin (90%, 82%, and 90% respectively).


Year 2016-October

The influenza positivity rate in October is quite similar compared to previous month, but a lot higher compared to the same period last year. Influenza B was still the most predominant subtype detected, followed by influenza A/H3N2. 32 out of 134 samples from children less than 5 years of age were tested positive with respiratory syncytial virus (RSV). In October 2016, 3 SARI samples were isolated with Klebsiella pneumoniae. Drug sensitivity was 100% with Gentamicin and 100% resistant to Ampicillin.


Year 2016-September

The influenza positivity rate in September is quite lower than previous months. The number of positive cases is approximately half that of August, and influenza B was still the most predominant subtype detected. In September 2016, 6 SARI samples were isolated with Pseudomonas aeruginosa. Drug sensitivity was very high with Ceftazidime, Gentamicin and Cirproloxacin.


Year 2016-August

The influenza positivity rate in August is quite higher than previous months. The number of positive cases is almost two folds compared to July, and 60% are influenza B. Burkholderia pseudomallei were isolated in four samples, of which drug sensitivity was 100% with Ceftazidime, Imepenem, Amoxicillin-Clavulanic Acid and Trimethroprim-Sulfamethoxozole. At least 75% of the isolates were resistant to Ciprofloxacin and Gentamicin.


Year 2016-July

Influenza activities in July were quite similar to previous month of June. In some sentinel sites, the infectivity positive rate was higher compared to June. Influenza A/H1N1 pdm was still the predominant subtype, followed by influenza B.
Drug sensitivity for Pseudomonas aeruginosa was 100% with Ceftazidime and Ciprofloxacin. The sensitivity to Gentamicin was 80%.


Year 2016-June

There was an increase of influenza activity in June 2016 both in ILI and SARI compared to May. An outbreak of influenza A/H1N1 was detected in Chak Klan village, Prey Veng province, in South-Eastern region of the country. No death was reported during the outbreak.
Similar to previous month, influenza A/H1N1 was the predominantly circulating subtype in June.
Klebsiella Species was found to be highly resistant to Ampicillin, Amoxicillin Clavulanic Acid, and Ceftriaxone.


Year 2016-May

Overall, the influenza activity in May 2016 is quite similar to that of April with respect to both influenza positive rate (IPR) and consultation rate. No cluster of respiratory disease was reported in May. Influenza A/H1N1pdm was the most predominantly identified subtypes.
Five SARI samples were isolated with Klebsiella Pneumonia. Sensitivity was high with Ceftriaxone and Gentamycin, but low with Ampicillin and Amoxicillin Clavulanic.


Year 2016-April

The influenza activity in April 2016 is quite similar to that of previous month with respect to both influenza positive rate (IPR) and consultation rate. No cluster of respiratory disease was detected in April.
In 2016 from January to April 2016, 9 SARI samples were isolated with Pseudomonas aeruginosa. Sensitivity was high for Gentamycin, Ceftazidime and Imipenem, but low with Ceftriaxone and Ciprofloxacin.


Year 2016-March

In March 2016, the influenza activity is quite similar to that of previous month, February as well as same period last year.
Influenza A/H1N1pdm is the most predominant subtype identified. Three samples (since October 2015) identified with
Burkholderia Pseudomallei were all sensitive to Ceftazidime and Imipenem but tend to be resistant with Amoxicillin Clavulanic
Acid and Gentamycin.


Year 2016-February

The influenza activity in February 2016 was lower compared to last month in January but quite higher compared to the same period last year. Influenza A/H1N1pdm was predominantly detected compared to influenza B. 7 samples were teste positive for Respiratory Syncytial Virus (RSV) among 79 samples of children less than 5 years.


Year 2016-January

Detection of influenza in January 2016 was lower compared to last month (December 2015) but higher compared to the same period last year (January 2016). Influenza B was the most predominantly detected virus. 7 samples were tested positive for Respiratory Syncytial Virus (RSV) among 79 samples of children less than 5 years.
