COVID-19感染者数増加：知っておくべきこと
COVID 19 levels on the rise. What you need to know. In recent weeks, a subtle yet concerning trend has emerged across parts of the United States. COVID 19 cases are beginning to tick upward in specific regions. While overall activity remains relatively low nationwide, certain states in the West, South, and Southeast are seeing noticeable increases in infections. According to the latest respiratory virus updates from the Centers for Disease Control and Prevention, CDC, this development raises questions about whether we’re witnessing the early signs of another wave or just minor fluctuations in an otherwise stable situation. But here’s where it gets controversial. Could these regional upticks signals a broader resurgence? Or are they isolated anomalies that will fade as quickly as they appeared? One of the key indicators of this trend is emergency department visits related to CO 19. Nationally, such visits remain extremely low, accounting for just 0.5% of all visits. However, there was a significant 10.9% jump compared to the previous week with younger children, particularly those aged 4 years old and under, experiencing even sharper rises. Another telling metric is test positivity rates, which have edged slightly higher at the national level, now standing at 4.8%. That’s an increase of 1.1 percentage points over the past week. A small shift, but one that experts say warrants close monitoring. Wastewater surveillance, often considered a reliable early warning system for viral spread, also paints a revealing picture. Earlier this summer, levels of SARS COV 2 detected in wastewater were classified as very low, but they’ve since climbed into the low range. The most pronounced spikes are occurring in western states, followed closely by southern regions. Among the states reporting elevated levels are California, Florida, Hawaii, Louisiana, Nevada, South Carolina, and Texas. These findings underscore the importance of continued vigilance, especially given that the CDC hasn’t updated its variant proportion projections since midJune due to limited sequencing data. When last reported, newer subvariants like NV.1.8.1 and XFG were gaining ground, though their exact impact remains unclear. Meanwhile, on the other side of the Atlantic, Europe is grappling with its own set of challenges involving mosquito-born illnesses. Italy recently confirmed its first locally transmitted case of Chikonga since 2017, originating in the Piachensaw province within the Amelia Romana region. This marks the second instance of locally acquired Chikonga in mainland Europe this year following France’s confirmation of 30 cases spread across 12 administrative regions. Notably, the largest cluster comprising 13 cases was identified in Salanda Province located in the Bushes Duron department in southern France. Denge fever, another mosquito-born disease, is also making headlines in Europe. Both France and Italy have reported their first local denge cases of the year. In France, the infection surfaced in the picturesque lore valley, while Italy’s case originated in the Bolognia province. Each country recorded only a single instance so far, but Portugal had already documented two denge cases earlier this year in Madiraa. According to the European Center for Disease Prevention and Control, ECDC, these cases likely reflect transmission events that occurred in 2024. Earlier this month, the ECDC took proactive steps by launching a new series of updates focused on mosquito-born diseases. Alongside this initiative, the agency released comprehensive guidance aimed at addressing locally acquired mosquito-ransmitted illnesses across Europe. These efforts highlight the growing concern among health officials about the potential for outbreaks driven by climate change, urbanization, and global travel patterns. So, what does all of this mean for us moving forward? Are we adequately prepared for the possibility of renewed CO 19 surges both domestically and globally? and how should public health systems respond to the dual threat of respiratory viruses and mosquito-born diseases. These are critical questions that demand thoughtful discussion and your input matters. Do you think governments and health organizations are doing enough to stay ahead of these threats?

Imagine a world where COVID 19 cases are on the rise again, just as we thought we were getting back to normal. Unfortunately, that’s the reality we’re facing right now with the Centers for Disease Control and Prevention, CDC, reporting a surge in cases across the country. But here’s the thing. This summer wave of COVID 19 was predictable and experts have been warning us about it for months. So, what’s behind this latest spike and how can you protect yourself and your loved ones? Let’s dive into the latest data and expert insights to find out. According to the CDC’s latest report, the number of CO 19 cases is now growing or likely growing in at least 26 states and Washington DC. This means that nearly half of the country is experiencing an increase in cases with some areas seeing a more significant surge than others. But what’s driving this summer wave? One major factor is the emergence of new coid9 variants such as nimbus and strraus. While these variants are not more deadly than previous ones, they can still cause severe illness, especially in vulnerable populations like young children, the elderly, and those with compromised immune systems. And this is the part most people miss. Even if you’re not in a high-risisk group, you can still get sick and experience debilitating symptoms. So, what can you do to protect yourself? Getting vaccinated is still one of the best ways to prevent severe illness and hospitalization. However, the CDC’s vaccine recommendations have shifted in recent months, leaving some people wondering if they should get a booster shot. The answer is not a simple yes or no. While the CDC still recommends that most adults get a 2024 to 2025 coid9 vaccine, the agency now suggests shared clinical decision-making for healthy children and pregnant people. This means that you should talk to your clinician about your individual risk factors and make an informed decision together. But here’s where it gets controversial. Some experts argue that the CDC’s recommendations are not clear-cut enough, leaving room for confusion and misinformation. Others argue that the agency is being too cautious and that more people should be encouraged to get vaccinated. So, what do you think? Should the CDC provide more straightforward guidance on COVID 19 vaccination or is the current approach sufficient? Let us know in the comments. In the meantime, here are the states where COVID 19 cases are growing according to the CDC. Arkansas, Hawaii, Illinois, Iowa, Kentucky, North Carolina, Ohio, Pennsylvania, Texas, and Virginia. And here are the places where cases are likely growing. Alaska, California, Delaware, District of Columbia, Georgia, Indiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, New Jersey, New York, Oklahoma, South Carolina, Tennessee, and Wisconsin. As we navigate this summer wave of CO 19, it’s essential to stay informed, take precautions, and make informed decisions about our health. So stay tuned for more updates, and let’s work together to stay safe and healthy. Co 19 cases rise in California. Is this the start of a summer wave? COVID cases are climbing once again in California. Could this be the onset of the dreaded summer wave? This rise in infections is stirring concern among health officials and residents alike as recent data points to an uptick that many have been anticipating but hoped to avoid. According to the latest public health reports, COVID 19 infections are increasing in about half of the US states with California among the hardest hit. The Centers for Disease Control and Prevention, CDC, released an update last Friday showing that more than two dozen states, especially those in the southeast, southern regions, and along the West Coast, are experiencing heightened virus activity. California is clearly part of this trend. Nationwide, COVID 19 levels as measured through wastewater monitoring, a tool that detects viral particles shed in sewage have risen from very low to medium just within one week. This change underscores a distinct upward trajectory in virus spread. In California specifically, wastewater surveillance programs like Wastewater Scan, which systematically test sewage samples across the state, have found virus traces at 95% of their monitored sites. The detected virus concentrations have been climbing since June, confirming that the virus is actively circulating within communities. Researchers pointed out in a report dated July 14th that such increases during summer months have become somewhat expected. However, this does not mean we should become complacent. The CDC also reports that as of last month, approximately 150 people per week have died from CO 19 nationwide, reminding us that despite familiarity, the virus remains deadly for many. So, what’s driving this summer surge? Health experts believe multiple factors are at play. increased travel around the Fourth of July holiday, large events such as concerts and sports games that gather crowds, people retreating indoors due to heat waves where the virus can spread more easily, and waning immunity among individuals whose last vaccination or infection occurred over 6 months ago. Although the current virus levels are somewhat below what was seen at this time last year, the study climb fits a recognizable seasonal pattern without a sudden spike yet observed. Genetic sequencing of virus samples collected from wastewater reveals the LP.8.1 variant is currently the leading strain in California accounting for about a third 33.2% of the sequences. Following closely is the XFG variant at nearly 25%. The NB.1.8.1 8.1 variant, nicknamed Nimbus and informally known as the razor blade throat variant because of reports describing sore throats that feel sharp or painful is present but less dominant, making up about 7.5% of samples. Despite its dramatic nickname, there is no clear evidence that the NV.1.8.1 variant causes more severe disease or higher rates of hospitalization. Nevertheless, health authorities continue to emphasize the importance of vaccination, especially for vulnerable groups, recommend testing if you experience COVID symptoms, and advise wearing masks in high-risisk settings. Dr. Peter Chinhong, an infectious disease specialist at UCSF, stresses the importance of vaccination for certain populations. If you are over 65, imunompromised, pregnant, or caring for infants under 2 years of age, it’s crucial to have had a COVID vaccine within the past year. Here’s where it gets particularly interesting and perhaps controversial. A recent CDC study published on Thursday suggests that CO 19 is settling into a predictable cyclical pattern with two annual surges. One typically between July and September and another from December through February. This bianual rhythm is thought to stem from ongoing genetic changes in the spike proteins S1 region which influences how well the virus can infect human cells. The CDC report noted, “Our analysis uncovered a repeating pattern of COVID peaks in late summer and winter that is likely to continue as long as the virus evolves and maintains diversity in the S1 region. Those familiar with California will recognize this pattern. Historically, the state’s summer wave tends to peak sometime between mid July and late August. So, what does this mean for you and your family? While the rise in cases may seem like deja vu, it serves as a useful reminder that the fight against CO isn’t over. Should public health measures stay the same? Or is it time to rethink our approach given these predictable surges? And with newer variants in circulation, how prepared are we really for what’s next? We want to hear your thoughts. Do you believe these seasonal waves should trigger new restrictions or precautions? or is it time to live with COVID as an ongoing seasonal illness?
