2. Responding to ticks
Ticks transmit infectious diseases such as severe fever with thrombocytopenia syndrome(SFTS). As of February 2015, a total of 110 SFTS cases have been reported in 15 prefectures
in western Japan mainly in the months of May, June, July, and August. Ticks carrying SFTS
virus have also been found in other prefectures.
Based on information from the Ministry of Health, Labour and Welfare, the Arakawa Clean-aidForum recommends the following measures with which participating groups can plan
accordingly.

3. Responding to PM2.5
PM2.5 refers to tiny particles in the air with a size less than 2.5μm (1μm is a thousandth of1mm). With the spread of severe PM2.5 air pollution in China and the PM2.5 level in Japan also
on the rise, there are concerns for its adverse health effects. Based on information from theMinistry of Health, Labour and Welfare, the Arakawa Clean-aid Forum recommends thefollowing measures with which participating groups can plan accordingly.

◇ Recommendations from the Arakawa Clean-aid Forum ◇① When daily average forecast is between 70μ(micro)g/㎥ and 140μ(micro)g/㎥（the average concentration at 5:00, 6:00, 7:00 am on the day exceeds 85μg/㎥）→※The daily average is expected to be over 70μg/㎥ when it measures more than
85μg/㎥ in the morning.
 No need to cancel the activity
 Alerting participants・ PM concentration levels
・ Those with respiratory or circulatory conditions, young children or the elderly shouldtake precautions as they are more likely to be affected
・ Plan emergency response including medical services and staff assignments in case ofaccidents
・ Consider handing out general use masks.
（Filtering effects differ depending on mask type）② When daily average forecast exceeds140 μ(micro)g/㎥
 Cancel the activity（※Daily average concentration has never exceeded 140μg/㎥(As of 2015.3.5)）

4. Responding to Dengue fever
Dengue fever is transmitted by mosquitoes (tiger mosquito or Aedes albopictus in Japan) thatfeed on the blood of an infected person. The virus that causes Dengue multiplies inside thebody of the mosquito which then passes on the infection by biting another individual. Typicalsymptoms include high fever, joint pain, pain behind eyes lasting for a week or two although insome cases infected people will develop no symptoms.
Based on information from the Ministry of Health, Labour and Welfare, the Arakawa Clean-aid
Forum recommends the following measures with which participating groups can planaccordingly.

◇ Recommendations from the Arakawa Clean-aid Forum ◇【Alerting participants】
 （In advance and on the day）Make sure to wear clothes that cover the arms, legs, andthe neck and do not expose the skin.
