Many patients and their families expressed their concerns about not knowing to what degree they should be worried about the novel coronavirus disease (COVID-19). It is understandable that people are feeling unease. It is also very important for people to be mindful of responding to it proportionately.
Coronaviruses are a group of viruses that are common in different animals. Classical coronavirus infection causes common cold with minor symptoms. In contrast, the new coronavirus is responsible for the outbreak of coronavirus disease 2019 (COVID-19), a possibly lethal respiratory disease. COVID-19 can infect both humans and bats, similar to the coronaviruses that cause SARS and MERS. The clinical course of COVID-19 is not completely understood. Symptoms typically appear after 1~12.5 days of contact with sick people.
According to Report of the WHO-China Joint Mission on Coronavirus Disease 2019 (COVID-19), “as of 20 February 2020 and based on 55924 laboratory confirmed cases, typical signs and symptoms include: fever (87.9%), dry cough (67.7%), fatigue (38.1%), sputum production (33.4%), shortness of breath (18.6%), sore throat (13.9%), headache (13.6%), myalgiaor arthralgia (14.8%), chills(11.4%), nausea or vomiting (5.0%), nasal congestion (4.8%), diarrhea (3.7%), and hemoptysis (0.9%), and conjunctival congestion (0.8%)" (p.12).
Most patients get well within a week. Some may develop pneumonia that causes several symptoms such as prolonged high fever, cough and difficulty in breathing. There is no specific medicine recommended to prevent or treat COVID-19 for the time being. As such, the major therapeutic approach is to relieve the symptoms. Elderly people and people with underlining diseases such as lung diseases, heart diseases, kidney diseases, diabetes, and immune deficiency are at high risk.
Things we should do include:
Wash your hands with soap and clean, running water
Don't touch your eyes, nose and mouth. Virus enters through these routes
If you are sick, wear a mask
Stay home when you are ill
Cough or sneeze into your elbow or upper sleeve, not your hands
If you are worried about getting regular pneumonia, which may be caused by simultaneous infection with bacteria and flu, you may wish to consider pneumococcal vaccination and flu shots
We have to keep in mind that the symptoms of COVID-19 mentioned above are frequently found in other diseases such as common cold and flu. Are you worried about your symptoms? We do not refuse patients who may have flu-like symptoms. Please contact us for an appointment.
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.
Wash your hands regularly using soap and water. Don't forget to moisturize your hands after washing.
Avoid touching your mouth, eyes and nose.
Stay away from crowds if possible.
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.

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.
