According to Tokyo Metropolitan Infectious Disease Survey Center, more people are infected with influenza/flu comparing to last year. The number of people who were infected with influenza from December 9 to December 15 this year is 6 times more than the people who got influenza during the same period last year. Tokyo Metropolitan Government has issued an infection warning (English version). As of December 20, 2019, a type A strain AH1pdm09 predominates in Tokyo, but many people were also infected with another type A strain AH3.

Influenza infection peaks from late January to February; type A prevails from December to February whereas the type B begins in February and lasts until spring. Fortunately, this year's flu vaccine is effective to all these strains. Immunization against flu is said to take between 2 to 4 weeks.

Our clinic still has some stocks of flu vaccines. If you have not had an opportunity to do flu shot this year, let's get it done as soon as possible!

Protect Your Family Against the Flu

According to News Updates from World Health Organization (WHO), one out of seven people are infected with influenza/flu every year. 


Flu is caused by infection with influenza viruses, which leads to high fever, stuffy nose, sore throat, dry cough, headache, muscle aches, and joint pains. 

The common cold also causes similar symptoms, but flu can pose severe consequences. In particular, influenza can be life-threatening, if complications arise, to people with compromised immunity, people suffering from chronic diseases such as diabetes, heart diseases and renal diseases, people aged 65 years old or above, and small children.  


WHO recommends five tips to prevent flu. 

  1. Get vaccinated

  2. Wash your hands regularly using soap and water. Don't forget to moisturize your hands after washing.

  3. Avoid touching your mouth, eyes and nose.

  4. Stay away from crowds if possible.

  5. Stay home, stay hydrated and sleep well when you feel sick.  


If you have not received your flu vaccination, consider making an appointment with your doctor.

Cough-variant asthma

Got a dry cough that doesn't go away?  You may have gotten cough-variant asthma.  Cough-variant asthma is the most frequent cause of lingering coughs in Japan.  Coughing is the only symptom of cough-variant asthma. Wheezing, shortness of breath, and viscous sputum are not found in cough-variant asthma. 


Exposure to allergens, house dust, infection (e.g. flu), tobacco smoke, cold air, sudden weather change, exercise, or stress often trigger coughing. 


The notoriously long and humid summer, air pollution and ticks make cough variant-asthma prevail in Japan.  Fall and spring are known to be the worst seasons for patients.  With autumn starting a while ago, an increasing number of patients have been diagnosed with this disease recently in our clinic. 


Cough-variant asthma goes on developing classic asthma if untreated.  It is very important to cure cough-variant asthma before it develops to typical asthma. 


Taking medications as directed by your doctor and reducing the exposure to risk factors are important to block the development of classic asthma. Our clinic is equipped with spirometer for diagnosing cough variant-asthma, asthma, and other conditions that may cause your breathing problems.
