Recently, many people, especially those with respiratory infections like the flu, have complained about slow recovery. Comments like “My cough hasn’t gone away, and I’m still feeling weak” are quite common. Infectious Diseases and Clinical Microbiology Specialist Prof. Dr. Meral Sönmezoğlu has explained the reasons behind this phenomenon.
Experts note a significant increase in cold cases since the second half of December. According to Prof. Dr. Sönmezoğlu, crowded environments in large cities have played a role in this rise. She emphasizes that the flu and other respiratory infections naturally increase during these months, saying:
“Cases always spike in December and January. This is an expected characteristic of winter months.” Prof. Dr. Sönmezoğlu further detailed the reasons behind the prolonged flu and respiratory infections
One reason for the prolonged recovery from the flu and other respiratory infections this year is the possibility of co-infections involving two viruses at once. Multiple viruses, such as RSV (Respiratory Syncytial Virus) or Rhinovirus, overlapping with flu or COVID-19, can delay recovery.
Additionally, due to mask-wearing during the pandemic, the immune system has become less familiar with these viruses, resulting in longer illnesses. Sinusitis, a common flu complication, can extend the illness by 10–15 days due to nasal congestion and sinus blockages that intensify symptoms. Another factor is the increased number of people who skipped the flu vaccine this year, weakening immunity and leading to longer disease durations.
A virus known as “human metapneumovirus” (hMPV) has recently caused an outbreak in China. While hMPV isn’t new (it’s been known since 2001), it rarely escalates to epidemic levels. This virus typically causes symptoms similar to the common cold..
In China, most cases have been observed in children and the elderly. Specifically, children under 14 and individuals over 60 are at higher risk for severe cases. However, there is no pandemic risk. Due to international travel, the outbreak has spread beyond China to Hong Kong, India, and neighboring countries.
In European countries, notably Romania, Influenza B has caused deaths in four individuals. However, these fatalities were influenced by personal health factors. Influenza B generally causes milder illness. In Turkey, flu cases, primarily Influenza A, are being closely monitored by the Ministry of Health. Current case numbers align with seasonal norms, with no signs of an epidemic. However, the low number of flu vaccinations could worsen the disease's impact. The World Health Organization reports a slight global increase in RSV, Influenza A-B, and COVID-19 cases.
An increase in flu cases is expected in the coming weeks, particularly in January and February 2025. This is because viruses spread more easily in enclosed spaces. However, simple measures can prevent the spread of these illnesses.
Wash and sanitize hands frequently. Avoid touching your mouth, nose, or eyes with unclean hands to prevent virus transmission from surfaces.
The risk of infection is higher in enclosed and crowded areas. Sick individuals should rest at home for at least three days to aid their recovery and protect public health.
Some countries have reintroduced mask mandates. In Turkey, wearing masks in crowded and enclosed areas, particularly public transportation, can prevent virus spread. Masks are unnecessary in open spaces.
Boost your immune system by eating a balanced diet rich in fruits, vegetables, and yogurt, and ensure sufficient sleep.
Limit behaviors such as hugging and kissing during winter. Avoid close contact with individuals showing cold symptoms.
